Common Palmar Digital Arteries
Three common palmar digital arteries arise from the convexity of the superficial palmar arch and proceed distally on the second, third, and fourth lumbricales muscles. Alternative names for these arteries are: common volar digital arteries, ulnar metacarpal arteries, arteriae digitales palmares communes, or aa. digitales volares communes. Each of these arteries receive the corresponding volar metacarpal artery and then divide into a pair of proper palmar digital arteries ( q.v.).

Anatomical Terms Of Location
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, '' Termi ...

Superficial Palmar Arch
The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the princeps pollicis artery, the radialis indicis artery, or the median artery, the former two of which are branches from the radial artery. Alternative names for this arterial arch are: superficial volar arch, superficial ulnar arch, arcus palmaris superficialis, or arcus volaris superficialis.Again, ''palmar'' and ''volar'' may be used synonymously, but ''arcus volaris superficialis'' does not occur in the TA, and can therefore be considered deprecated. The arch passes across the palm in a curve (Boeckel's line) with its convexity downward, With the thumb fully extended, the superficial palmar arch would lie approximately 1 cm from a line drawn between the first web space to the hook of hamate (Kapla ...

Proper Palmar Digital Arteries
The proper palmar digital arteries travel along the sides of the phalanges (along the contiguous sides of the index, middle, ring, and little fingers), each artery lying just below (dorsal (anatomy), dorsal to) its corresponding Dorsal digital nerves of ulnar nerve, digital nerve. Alternative names for these arteries are: proper volar digital arteries, collateral digital arteries, arteriae digitales palmares propriae, or aa. digitales volares propriae. Proper palmar digital arteries anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the Interphalangeal articulations of hand, interphalangeal joints. Dorsal branches supplied by the arteries anastomose with the dorsal digital arteries of hand, dorsal digital arteries, and supply the soft parts on the back of the second and third phalanges, including the matrix of the fingernail.

Palmar Digital Veins
The palmar digital veins (or volar digital veins) on each finger are connected to the dorsal digital veins by oblique intercapitular veins. Some sources distinguish between the "proper palmar digital veins", which are more distal, and the "common palmar digital veins", which are more proximal.

Convex
Convex or convexity may refer to: Science and technology * Convex lens, in optics Mathematics * Convex set, containing the whole line segment that joins points ** Convex polygon, a polygon which encloses a convex set of points ** Convex polytope, a polytope with a convex set of points ** Convex metric space, a generalization of the convexity notion in abstract metric spaces * Convex function In mathematics, a real-valued function is called convex if the line segment between any two distinct points on the graph of a function, graph of the function lies above or on the graph between the two points.

Lumbricals Of The Hand
The lumbricals are intrinsic muscles of the hand that flexion, flex the metacarpophalangeal joints, and extension (kinesiology), extend the Interphalangeal articulations of hand, interphalangeal joints. p. 97 The lumbrical muscle of the foot, lumbrical muscles of the foot also have a similar action, though they are of less clinical concern. Structure The lumbricals are four, small, worm-like muscles on each hand. These muscles are unusual in that they do not attach to bone. Instead, they attach proximally to the tendons of flexor digitorum profundus, and distally to the extensor expansions. The first and second lumbricals are Anatomical terms of muscle, unipennate, while the third and fourth lumbricals are Anatomical terms of muscle, bipennate. Nerve supply The first and second lumbricals (the most radial two) are Nerve, innervated by the median nerve. The third and fourth lumbricals (most ulnar two) are innervated by the deep branch of ulnar nerve. This is the usual inne ...

Synonym
A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all synonyms of one another: they are ''synonymous''. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words may often be synonymous in only one particular sense: for example, ''long'' and ''extended'' in the context ''long time'' or ''extended time'' are synonymous, but ''long'' cannot be used in the phrase ''extended family''. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms. Lexic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...

Terminologia Anatomica
''Terminologia Anatomica'' (commonly abbreviated TA) is the international standard for human anatomy, human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology (FIPAT) a program of the International Federation of Associations of Anatomists (IFAA). History The sixth edition of the previous standard, ''Nomina Anatomica'', was released in 1989. The first edition of ''Terminologia Anatomica'', superseding Nomina Anatomica, was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA) and released in 1998. In April 2011, this edition was published online by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT. The first edition contained 7635 Latin items. The second edition was released online by FIPAT in 2019 and approved and adopted by the IFAA General Assembly in 2020. The latest errata is dated Au ...

The palmar metacarpal arteries (volar metacarpal arteries, palmar interosseous arteries) are three or four arteries that arise from the convexity of the deep palmar arch.

They anastomose at the clefts of the fingers with the common palmar digital arteries which arise from the superficial palmar arch The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery.
