In humans, volar can also be used synonymously with palmar to refer to the underside of the palm, but plantar is used exclusively to describe the sole. These terms describe location as palmar and plantar; For example, volar pads are those on the underside of hands or fingers; the plantar surface describes the sole of the heel, foot or toes.
From there, it forms a palmar continuation of the articular surface of the phalanx bone and its inner surface thus adds to the articular surface during extension. [2] In its proximal end, the volar plate becomes membranous and blends with the volar capsule which is attached to the head of the metacarpal bone. During flexion, the plate glides ...
Palmar carpal ligament, the thickened portion of the deep forearm fascia on the front of the wrist; Palmar crease, a crease in the surface of the palm; Palmar digital nerves (disambiguation), several sets of nerves in the fingers; Palmar digital veins, blood vessels on the palm side of the fingers; Palmar erythema, reddening of the palms
The distal part of the palmar ligament, called the palmar plate, is 2 to 3 millimetres (0.079 to 0.118 in) thick and has a fibrocartilaginous structure. The presence of chondroitin and keratan sulfate in the dorsal and palmar plates is important in resisting compression forces against the condyles of the proximal phalanx. Together these ...
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 ...
A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through the body. Three planes are commonly referred to in anatomy and medicine: [1] [2]: 4 The sagittal plane is the plane that divides the body or an organ vertically into right and left sides.
The palmar surface is narrow, rounded, and rough, for the attachment of ligaments and a part of the adductor pollicis muscle. [1] The lateral surface articulates with the lesser multangular by a small facet at its anterior inferior angle, behind which is a rough depression for the attachment of an interosseous ligament.
