Theyre conventionally numbered 1 to 5 from lateral radial to medial ulnar side.

Anatomy of metacarpals. The second with the trapezium trapezoid capitate and third metacarpal. On the palm side they are covered with connective tissue. The insertion of the flexor carpi radialis at the base of the second metacarpal contributes as well.

The third with the capitate and second and fourth metacarpals. Besides the metacarpophalangeal joints the metacarpal bones articulate by carpometacarpal joints as follows. They consist of a proximal base a shaft and a distal head.

Scaphoid bone and trapezium flexor retinaculum. Carpal bones proximal a set of eight irregularly shaped bones. They can be divided into three categories.

Muscular attachments in the metacarpal area. Capitate base and bases of 2nd and 3rd metacarpal. Anatomy of the metacarpals parts of a metacarpal.

The metacarpals together are referred to as the metacarpus the tops of the metacarpals form the knuckles where they join to the wrist. The metacarpus is composed of 5 metacarpal bones. Capitate trapezium and flexor retinaculum.

They consist of a proximal base a shaft and a distal head. Theyre conventionally numbered 1 to 5 from lateral radial to medial ulnar side. Metacarpals there are five metacarpals each one related to a digit.

The articulation with the hamate and the fourth and fifth metatarsal bases allows for much freer movement but the cmc and metacarpal ligaments are still very strong. They are five in number one for each digit and lie side by side and slightly divergent from each other being separated by intervals called interosseous spaces. The fourth with the.

The metacarpals are long bones within the hand that are connected to the carpals or wrist bones and to the phalanges or finger bones. The metacarpal bones form the skeleton of the palm articulating proximally with the carpus and distally with the digits. 1st metacarpal radial border adductor pollicis origin.

This metacarpal has multiple articular facets on its base which is shaped somewhat like a styloid process with an articular facet on the radial dorsal surface for articulating with the distal carpal bone capitate. Capitate base and bases of 2nd and 3rd metacarpal. Each finger has three phalanges.

The first with the trapezium. These are located in the wrist area. The metacarpus of the hand is composed of five bony structures known as the metacarpals.
