   What are proximal phalanges?

   • The proximal phalanges are very mobile at the MCP joints. They are mainly capable of flexion, extension, adduction and abduction. Circumduction and rotation are also possible, especially at the MCP joint of the thumb. These movements are enabled by the action of several muscles;

   What muscles extend the proximal interphalangeal joint?

   • The muscles responsible for extension of the proximal interphalangeal joint form a complicated array of tendons and insertions along the finger. The proximal interphalangeal joint is primarily extended by the central slip tendon, which inserts at the base of middle phalanx on the dorsal aspect.

   What muscles flex the distal phalanges?

   • The distal phalanges are capable of flexion and extension at the DIP joints. Two forearm extensors and one flexor muscle insert directly into the bases of the distal phalanges, permitting these actions. These include flexor digitorum profundus, flexor pollicis longus and extensor pollicis longus.

   What ligaments attach to the proximal phalanges?

   • The collateral and palmar metacarpophalangeal ligaments attach to the bases of the proximal phalanges. They provide strength to the metacarpophalangeal joints. The collateral interphalangeal ligaments of hand attach to the heads, supporting the PIP joints.

   Oct 24, 2023 · The extensor pollicis brevis and extensor pollicis longus muscles are responsible for thumb extension at the 1st MCP joint. The extensor digitorum communis creates tension over the sagittal bands and pulls them over the proximal phalanx to hyperextend the MCP joints.

   Oct 30, 2023 · Each metacarpophalangeal joint is formed by the convex heads of the metacarpal bones which are received by the concave bases of the proximal phalanges. The primary movements of the metacarpophalangeal joints are flexion, extension, abduction, adduction, circumduction and limited rotation.

   Aug 14, 2023 · The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage.
