Thumb Open Paper Cut- Photo
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: 1) Any of the five terminal members of the hand. 2) Any of the four terminal members of the hand, other than the thumb. Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness.

Distal
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. 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 axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Terminologia ...

Carpometacarpal Joint
The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately. Thumb The carpometacarpal joint of the thumb (''pollex''), also known as the first carpometacarpal joint, or the trapeziometacarpal joint (TMC) because it connects the trapezium to the first metacarpal bone, plays an irreplaceable role in the normal functioning of the thumb. The most important joint connecting the wrist to the metacarpus, osteoarthritis of the TMC is a severely disabling condition; it is up to twenty times more common among elderly women than in the average. Pronation-supination of the first metacarpal is especially important for the action of opposition. The movements of the first CMC are limited by the sha ...

Prudence Hero Napier
Prudence Hero Napier (; 15March 19166June 1997) was one of Britain's most eminent primatologists, and the world's leading expert on the taxonomy of primates.''International Journal of Primatology'', Vol. 19, Number 2/ April, 1998. pp. 203-05 Biography Known to friends and colleagues as Prue, she was born in Liverpool on 15 March 1916, to Sir Hugo Rutherford, a politician and Member of Parliament for North Liverpool. In 1936, she married the newly graduated surgeon John Napier, who had acquired a particular interest in the anatomy of the human hand. During the 1950s he became convinced that human functional anatomy could not be properly understood without in-depth knowledge of non-human primates and, with Prue's help, he founded the Unit of Primatology in the Royal Free Hospital School of Medicine, which, at that time, was the first centre in Great Britain devoted to the study of non-human primates. Prudence became her husband's colleague and co-author. She contributed to ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Napier (primatologist)
John Russell Napier, MRCS, LRCP, D.Sc. (11 March 1917 – 29 August 1987) was a British primatologist, paleoanthropologist, and physician, who is notable for his work with ''Homo habilis'' and OH 7, as well as on human and primate hands/feet. During his life he was widely considered a leading authority on primate taxonomy, but is perhaps most famous to the general public for his research on Bigfoot. Biography Napier was an orthopedic surgeon at the University of London before being invited by Sir Wilfrid Le Gros Clark to join him in his paleoanthropology research. Napier then dedicated his life afterward to primatology, becoming the founder of the Primate Society of Great Britain, and was among the group, with Louis Leakey and Philip Tobias, that named ''Homo habilis'' in the 1960s.

Circumduction (anatomy)
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomic ...

Opponens Digiti Minimi Muscle
The opponens digiti minimi (opponens digiti quinti in older texts) is a muscle in the hand. It is of a triangular form, and placed immediately beneath the palmaris brevis, abductor digiti minimi and flexor digiti minimi brevis. It is one of the three hypothenar muscles that control the little finger. It arises from the convexity of the hamulus of the hamate bone and the contiguous portion of the transverse carpal ligament; it is inserted into the whole length of the metacarpal bone of the little finger, along its ulnar margin. The opponens digiti minimi muscle serves to flex and laterally rotate the 5th metacarpal about the 5th carpometacarpal joint, as when bringing the little finger and thumb into opposition. It is innervated by the deep branch of the ulnar nerve.

Opponens Pollicis Muscle
The opponens pollicis is a small, triangular muscle in the hand, which functions to oppose the thumb. It is one of the three thenar muscles. It lies deep to the abductor pollicis brevis and lateral to the flexor pollicis brevis. Structure The opponens pollicis muscle is one of the three thenar muscles. It originates from the flexor retinaculum of the hand and the tubercle of the trapezium. It passes downward and laterally, and is inserted into the whole length of the metacarpal bone of the thumb on its radial side. Innervation Like the other thenar muscles, the opponens pollicis is innervated by the recurrent branch of the median nerve. In 20% of the population, opponens pollicis is innervated by the ulnar nerve. Blood supply The opponens pollicis receives its blood supply from the superficial palmar arch. Function ''Opposition of the thumb'' is a combination of actions that allows the tip of the thumb to touch the tips of other fingers. The part of apposition that this m ...

Apposition
Apposition is a grammatical construction in which two elements, normally noun phrases, are placed side by side so one element identifies the other in a different way. The two elements are said to be ''in apposition'', and the element identifying the other is called the appositive. The identification of an appositive requires consideration of how the elements are used in a sentence. For example, in these sentences, the phrases ''Alice Smith'' and ''my sister'' are in apposition, with the appositive identified with italics: * My sister, ''Alice Smith'', likes jelly beans. * Alice Smith, ''my sister'', likes jelly beans. Traditionally, appositives were called by their Latin name ''appositio'', derived from the Latin ''ad'' ("near") and ''positio'' ("placement"), although the English form is now more commonly used. Apposition is a figure of speech of the scheme type and often results when the verbs (particularly verbs of being) in supporting clauses are eliminated to produce sho ...
