They are used in anatomy, surface anatomy, surgery, and radiology. Structures may be described as being at the level of a specific spinal vertebra , depending on the section of the vertebral column the structure is at. The position is often abbreviated. For example, structures at

312-414: A standard set of terms to communicate clearly the position of a structure. Standard anatomical and zoological terms of location have been developed, usually based on Latin and Greek words, to enable all biological and medical scientists, veterinarians , doctors and anatomists to precisely delineate and communicate information about animal bodies and their organs, even though the meaning of some of
364-403: A state in which a part further away is abnormally placed towards (varus) or away from (valgus) the midline. The terms proximal (from Latin proximus 'nearest') and distal (from Latin distare 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively. Thus the upper arm in humans
416-452: A wound on the upper arm, but proximal to a wound on the lower arm. The terms are also applied to internal anatomy, such as to the reproductive tract of snails . Unfortunately, different authors use the terms in opposite senses. Some consider "distal" as further from a point of origin near the centre of the body and others as further from where the organ reaches the body's surface; or other points of origin may be envisaged. This terminology
468-674: Is bipedal or quadrupedal . Additionally, for some animals such as invertebrates , some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, Terminologia Anatomica for humans and Nomina Anatomica Veterinaria for animals. These allow parties that use anatomical terms, such as anatomists , veterinarians , and medical doctors , to have
520-413: Is also employed in molecular biology and therefore by extension is also used in chemistry, specifically referring to the atomic loci of molecules from the overall moiety of a given compound. Central and peripheral refer to the distance towards and away from the centre of something. That might be an organ, a region in the body, or an anatomical structure. For example, the central nervous system and
572-402: Is proximal and the hand is distal. "Proximal and distal" are frequently used when describing appendages , such as fins , tentacles , and limbs . Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or distal in relation to another point of reference. Thus the elbow is distal to

#1732786743195624-402: Is rarely used in human anatomy, apart from embryology, and refers more to the front of the face than the superior aspect of the organism. Similarly, the term "caudal" is used more in embryology and only occasionally used in human anatomy. This is because the brain is situated at the superior part of the head whereas the nose is situated in the anterior part. Thus, the "rostrocaudal axis" refers to
676-481: Is roughly symmetrical. To do this, distinct ends of an organism are chosen, and the axis is named according to those directions. An organism that is symmetrical on both sides has three main axes that intersect at right angles . An organism that is round or not symmetrical may have different axes. Example axes are: Examples of axes in specific animals are shown below. Several terms are commonly seen and used as prefixes : Other terms are used as suffixes , added to
728-408: Is the "upper lip" which is in the front area of the head and is the most exterior part. A pair of mandibles is found on the backside of the labrum flanking the side of the mouth, succeeded by a pair of maxillae each of which is known as maxilliary palp . At the back side of the mouth is the labium or lower lip. There is also an extra mouth part in some insects which is termed as hypopharynx which
780-488: Is the part of an organism which usually includes the ears , brain , forehead , cheeks , chin , eyes , nose , and mouth , each of which aid in various sensory functions such as sight , hearing , smell , and taste . Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size. Heads develop in animals by an evolutionary trend known as cephalization . In bilaterally symmetrical animals, nervous tissue concentrate at
832-458: Is to the head or tail of an animal. To describe how close to the head of an animal something is, three distinct terms are used: For example, in horses , the eyes are caudal to the nose and rostral to the back of the head. These terms are generally preferred in veterinary medicine and not used as often in human medicine. In humans, "cranial" and "cephalic" are used to refer to the skull, with "cranial" being used more commonly. The term "rostral"
884-434: Is to the midline, or the medial plane. Lateral (from Latin lateralis 'to the side') describes something to the sides of an animal, as in "left lateral" and "right lateral". Medial (from Latin medius 'middle') describes structures close to the midline, or closer to the midline than another structure. For example, in a human, the arms are lateral to the torso . The genitals are medial to
936-424: Is usually located between the maxillac . Though invertebrate chordates – such as the tunicate larvae or the lancelets – have heads, there has been a question of how the vertebrate head, characterized by a bony skull clearly separated from the main body, might have evolved from the head structures of these animals. According to Hyman (1979), the evolution of the head in the vertebrates has occurred by
988-478: The anatomy of animals , including humans . The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position . This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes . The meaning of terms that are used can change depending on whether an organism
1040-410: The anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head. The human head is an anatomical unit that consists of the skull , hyoid bone and cervical vertebrae . The term "skull" collectively denotes the mandible (lower jaw bone) and
1092-438: The anterior superior iliac spine , the medial malleolus or the medial epicondyle . Anatomical lines are used to describe anatomical location. For example, the mid-clavicular line is used as part of the cardiac exam in medicine to feel the apex beat of the heart . Special terms are used to describe the mouth and teeth. Fields such as osteology , palaeontology and dentistry apply special terms of location to describe

#17327867431951144-444: The cephalon , or cephalic region, is the region of the head which is a collective of "fused segments". A typical insect head is composed of eyes, antennae , and components of mouth. As these components differ substantially from insect to insect, they form important identification links. Eyes in the head found, in several types of insects, are in the form of a pair of compound eyes with multiple faces. In many other types of insects,
1196-402: The cranium (upper portion of the skull that houses the brain). ) ] Sculptures of human heads are generally based on a skeletal structure that consists of a cranium, jawbone , and cheekbone . Though the number of muscles making up the face is generally consistent between sculptures, the shape of the muscles varies widely based on the function, development, and expressions reflected on
1248-449: The head . Anterior (from Latin ante 'before') describes what is in front, and posterior (from Latin post 'after') describes what is to the back of something. For example, for a dog the nose is anterior to the eyes and the tail is considered the most posterior part; for many fish the gill openings are posterior to the eyes but anterior to the tail. These terms describe how close something
1300-648: The neuraxis is different between the two groups, and so is what is considered the standard anatomical position , such as how humans tend to be standing upright and with their arms reaching forward. Thus, the "top" of a human is the head, whereas the "top" of a dog would be the back, and the "top" of a flounder may be on either the left or right side. Unique terms are also used to describe invertebrates as well, because of their wider variety of shapes and symmetry. Because animals can change orientation with respect to their environment, and because appendages like limbs and tentacles can change position with respect to
1352-467: The pectoralis major muscle). In radiology , an X-ray image may be said to be "anteroposterior", indicating that the beam of X-rays, known as its projection, passes from their source to patient's anterior body wall first, then through the body to exit through posterior body wall and into the detector/film to produce a radiograph. The opposite is true for the term "posteroanterior," while side-to-side projections are known as either "lateromedial" (from
1404-415: The peripheral nervous systems . Central (from Latin centralis ) describes something close to the centre. For example, the great vessels run centrally through the body; many smaller vessels branch from these. Peripheral (from Latin peripheria , originally from Ancient Greek ) describes something further away from the centre of something. For example, the arm is peripheral to
1456-400: The body in a standing position with arms at the side and palms facing forward, with thumbs out and to the sides. Many anatomical terms can be combined, either to indicate a position in two axes simultaneously or to indicate the direction of a movement relative to the body. For example, "anterolateral" indicates a position that is both anterior and lateral to the body axis (such as the bulk of
1508-570: The body. These terms refer to the distance of a structure from the surface. Deep (from Old English ) describes something further away from the surface of the organism. For example, the external oblique muscle of the abdomen is deep to the skin. "Deep" is one of the few anatomical terms of location derived from Old English rather than Latin – the anglicised Latin term would have been "profound" (from Latin profundus 'due to depth'). Superficial (from Latin superficies 'surface') describes something near
1560-417: The closeness to the midline of the dental arch. Terms used to describe structures include "buccal" (from Latin bucca 'cheek') and "palatal" (from Latin palatum 'palate') referring to structures close to the cheek and hard palate respectively. Several anatomical terms are particular to the hands and feet. Additional terms may be used to avoid confusion when describing
1612-545: The compound eyes are seen in a "single facet or group of single facets". In some cases, the eyes may be seen as marks on the dorsal or located near or toward the head, two or three ocelli (single faceted organs). Antennae on the insect's head is found in the form of segmented attachments, in pairs, that are usually located between the eyes. These are in varying shapes and sizes, in the form of filaments or in different enlarged or clubbed form. Insects have mouth parts in various shapes depending on their feeding habits. Labrum

1664-421: The end of words: Superior (from Latin super 'above') describes what is above something and inferior (from Latin inferus 'below') describes what is below it. For example, in the anatomical position , the most superior part of the human body is the head and the most inferior is the feet. As a second example, in humans, the neck is superior to the chest but inferior to
1716-578: The faces of the subjects. Proponents of identism believe that the mind is identical to the brain. Philosopher John Searle asserts his identist beliefs, stating "the brain is the only thing in the human head". Similarly, Dr. Henry Bennet-Clark has stated that the head encloses billions of "miniagents and microagents (with no single Boss)". The evolution of a head is associated with the cephalization that occurred in Bilateria some 555 million years ago. In some arthropods , especially trilobites ,
1768-435: The fusion of a fixed number of anterior segments, in the same manner as in other "heteronomously segmented animals". In some cases, segments or a portion of the segments disappear. The head segments also lose most of their systems, except for the nervous system. With the progressive development of cephalization, "the head incorporates more and more of the adjacent segments into its structure, so that in general it may be said that
1820-417: The hand') is commonly used to describe the front of the hand, and dorsal is the back of the hand. For example, the top of a dog 's paw is its dorsal surface; the underside, either the palmar (on the forelimb) or the plantar (on the hindlimb) surface. The palmar fascia is palmar to the tendons of muscles which flex the fingers, and the dorsal venous arch is so named because it is on the dorsal side of
1872-440: The higher the degree of cephalization the greater is the number of segments composing the head". In the 1980s, the "new head hypothesis" was proposed, suggesting that the vertebrate head is an evolutionary novelty resulting from the emergence of neural crest and cranial placodes . In 2014, a transient larva tissue of the lancelet was found to be virtually indistinguishable from the neural crest-derived cartilage which forms
1924-512: The legs. Temporal has a similar meaning to lateral but is restricted to the head. The terms "left" and "right" are sometimes used, or their Latin alternatives ( Latin : dexter , lit. 'right'; Latin : sinister , lit. 'left'). However, it is preferred to use more precise terms where possible. Terms derived from lateral include: Varus (from Latin 'bow-legged') and valgus (from Latin 'knock-kneed' ) are terms used to describe
1976-448: The level of the fourth cervical vertebra may be abbreviated as "C4", at the level of the fourth thoracic vertebra "T4", and at the level of the third lumbar vertebra "L3". Because the sacrum and coccyx are fused, they are not often used to provide the location. References may also take origin from superficial anatomy , made to landmarks that are on the skin or visible underneath. For example, structures may be described relative to

Leonardo da Vinci , considered one of the world's greatest artists, drew sketches of human anatomy using grid structures. His image of the face drawn on the grid structure principle is in perfect proportion. In this genre, using the technique of pen and ink, Leonardo created a sketch which is a "Study on
2080-401: The main body, terms to describe position need to refer to an animal when it is in its standard anatomical position . This means descriptions as if the organism is in its standard anatomical position, even when the organism in question has appendages in another position. This helps avoid confusion in terminology when referring to the same organism in different postures. In humans, this refers to
2132-456: The mouth and teeth. This is because although teeth may be aligned with their main axes within the jaw, some different relationships require special terminology as well; for example, teeth also can be rotated, and in such contexts terms like "anterior" or "lateral" become ambiguous. For example, the terms "distal" and "proximal" are also redefined to mean the distance away or close to the dental arch , and "medial" and "lateral" are used to refer to

2184-400: The outer surface of the organism. For example, in skin , the epidermis is superficial to the subcutis . These two terms, used in anatomy and embryology , describe something at the back ( dorsal ) or front/belly ( ventral ) of an organism. The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about

In the first circle, the division is made of five sections on the diameter , each section of five eyes width. It is then developed over a series of ten defined steps, with the smaller circle imposed partially over the larger circle at

Infants' or children's heads are often couped at the shoulders with a snake wrapped around the neck (e.g. "Argent, a boy's head proper, crined or, couped below the shoulders, vested gules, tarnished gold," in the arms of Boyman). One of the ways of drawing sketches of heads—as Jack Hamm advises—is to develop it in six well-defined steps, starting with
2444-442: The skull, the dorsal side is the top. The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. For example, in a fish, the pectoral fins are dorsal to the anal fin , but ventral to the dorsal fin . The terms are used in other contexts; for example dorsal and ventral gun turrets on a bomber aircraft. Specific terms exist to describe how close or far something
2496-460: The surfaces of the hand and what is the "anterior" or "posterior" surface. The term "anterior", while anatomically correct, can be confusing when describing the palm of the hand; Similarly is "posterior", used to describe the back of the hand and arm. This confusion can arise because the forearm can pronate and supinate and flip the location of the hand. For improved clarity, the directional term palmar (from Latin palma 'palm of

Combined terms were once generally hyphenated, but the modern tendency is to omit the hyphen. Anatomical terms describe structures with relation to four main anatomical planes : The axes of the body are lines drawn about which an organism
