Metacarpal anatomy. Anatomy of the metacarpals parts of a metacarpal. The head is provided with a surface for articulation with. The heads of the metacarpals hand bones will each in turn articulate with the bases of the proximal phalanx of the fingers and thumb.

The metacarpals together are referred to as the metacarpus the tops of the metacarpals form the knuckles where they join to the wrist. Each finger has three phalanges. Base of metacarpal bones.

They can be divided into three categories. The cam shape of the metacarpal heads leads to relaxation of the collateral ligaments in extension permitting adduction and abduction of the finger. The metacarpal bones are five long bones of the hand between the carpal bones and the proximal phalanges of the hand that make up most of the palm.

At these meeting points there are smooth surfaces upon the bones known as articular facets. The palmar surfaces of the metacarpal bones are slightly concave while the dorsal surfaces are the opposite and have triangular shaped distal heads. Gross anatomy the metacarpal bones run from the carpus forming the carpometacarpal joints to t.

Phalanges distal the bones of the fingers. They articulate proximally at their base with the distal row of carpal bones and communicate distally at their head with the proximal phalanges. The fourteen phalanges of hand bones make up the fingers and thumb and are numbered i v thumb to little finger while the hand is observed from an anatomical position palm up.

The metacarpal bones are analogous to the metatarsal bones in the foot. Head of metacarpal bones. On the palm side they are covered with connective tissue.

The metacarpal bones connect the wrist with the fingers. The metacarpal bones of the fingers have little freedom of movement while the thumb unlike the others is freely movable. The bases all more or less wedge shaped in form.

Metacarpals there are five metacarpals each one related to a digit. The metacarpophalangeal mcp joints are multiaxial condyloid joints capable of flexion extension and some lateral motion and circumduction. The bodies which are slightly curved towards the anterior aspect.

These are located in the wrist area. Blaisdell the knife must not go further down than the base of the metacarpal bones in case of dividing the deep palmar arch. The metacarpals are long bones within the hand that are connected to the carpals or wrist bones and to the phalanges or finger bones.

Muscular attachments in the metacarpal area. Metacarpal bones body shaft of metacarpal bones. In human anatomy the metacarpal bones or metacarpus form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist which forms the connection to the forearm.
