मेटाकार्पल इसके अंग्रेजी अर्थ का उदाहरण

The extensor tendons are connected to the second by a thin transverse band, known as the juncturae tendinum; they serve to maintain the central alignment of the extensor tendons over the metacarpal head, thus increasing the available leverage.

Injuries (such as by an external flexion force during active extension) may allow the tendon to dislocate into the intermetacarpal space; the extensor tendon then acts as a flexor and the finger may no longer be actively extended.

in length, the tendon passes through a long and superficial synovial sheath which, passing obliquely from the radial border of the forearm into the thumb, extends from the proximal border of the extensor retinaculum to the first carpometacarpal joint.

In the metacarpal region, beyond the synovial sheath, the tendon is supplied directly from the radial artery.

At the phalanges, the tendon forms a dorsal aponeurosis which is supplied by a digital branch of the first dorsal metacarpal artery.

This complete extension at the interphalangeal joint is not possible, or considerably more difficult, with the carpal, carpometacarpal, and metacarpophalangeal joints simultaneously extended.

It also applies an extensor force at the metacarpophalangeal joint together with the extensor pollicis brevis and extends and adducts at the carpometacarpal joint of the thumb.

The flexor pollicis brevis flexes the thumb at the metacarpophalangeal joint, as well as flexion and medial rotation of the 1st metacarpal bone at the carpometacarpal joint.

The abductor pollicis brevis does this by acting across both the carpometacarpal joint and the metacarpophalangeal joint.

In a close relationship to the abductor pollicis longus, the extensor pollicis brevis both extends and abducts the thumb at the carpometacarpal and metacarpophalangeal joints.

Muscles of the upper limb In [anatomy], the palmar or volar interossei (interossei volares in older literature) are three small, unipennate muscles in the hand that lie between the metacarpal bones and are attached to the index, ring, and little fingers.

All palmar interossei originate along the shaft of the metacarpal bone of the digit on which they act.

However, the deep head of the flexor pollicis brevis originates on the thumb's ulnar sesamoid bone and the oblique portion of the adductor pollicis on several carpal bones, as well as the bases of the second and third metacarpal bones and not on the first metacarpal.
