  2. Metacarpal bones - Wikipedia

    en.wikipedia.org/wiki/Metacarpal_bones

    Left hand shown with thumb on left. The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity.

  4. Deep palmar arch - Wikipedia

    en.wikipedia.org/wiki/Deep_palmar_arch

    The deep palmar arch is about a finger width proximal to this. The connection between the deep and superficial palmar arterial arches is an example of anastomosis. [1] This anastomosis can be tested for using Allen's test. The palmar metacarpal arteries arise from the deep palmar arch. [1]

  5. Carpometacarpal joint - Wikipedia

    en.wikipedia.org/wiki/Carpometacarpal_joint

    The proximal transverse arch of the palm is formed by the distal row of carpal bones. The concavity of this arch is augmented at the level of the metacarpal heads by the flexibility of the first, fourth, and fifth metacarpal heads around the fixed second and third metacarpal heads; a flexible structure called the distal transverse arch.

  6. Palmar metacarpal arteries - Wikipedia

    en.wikipedia.org/wiki/Palmar_metacarpal_arteries

    The palmar metacarpal arteries arise from the convexity of the deep palmar arch. [1]They run distally upon the palmar interossei muscles.They anastomose at the clefts of the fingers with the common palmar digital arteries which arise from the superficial palmar arch.

  7. Dorsal carpal arch - Wikipedia

    en.wikipedia.org/wiki/Dorsal_carpal_arch

    The dorsal carpal arch (dorsal carpal network, posterior carpal arch) is an anatomical term for the combination (anastomosis) of dorsal carpal branch of the radial artery and the dorsal carpal branch of the ulnar artery near the back of the wrist. It is made up of the dorsal carpal branches of both the ulnar and radial arteries.

  8. Deep venous palmar arch - Wikipedia

    en.wikipedia.org/wiki/Deep_venous_palmar_arch

    The deep palmar arch, an arterial network is accompanied by a pair of venae comitantes which constitute the deep venous palmar arch. It receives the veins corresponding to the branches of the arterial arch: the palmar metacarpal veins .

  9. Dorsal metacarpal arteries - Wikipedia

    en.wikipedia.org/wiki/Dorsal_metacarpal_arteries

    Most of the dorsal metacarpal arteries arise from the dorsal carpal arch and run downward on the second, third, and fourth dorsal interossei of the hand and bifurcate into the dorsal digital arteries. Near their origin, they anastomose with the deep palmar arch by perforating arteries.
