Dorsal interossei muscles of the hand
Imperial sizes are the traditional sizes measured in “inches” or “feet and inches”. This is caused by the weakness of the third and fourth lumbricals, in addition to the interossei. Conversely, the index and middle fingers are usually less affected in the ulnar claw because the first and second lumbricals can compensate for this loss up to a certain degree.

They have grooves attached together by horizontal supports known as ledges. The ledges provide support to the structure of this door because of the way they are attached horizontally over the vertical battens. The standard dimensions of these doors are 100 to 150 mm width and 20 to 30 mm thick for the battens, and 100 to 200 mm width and 25 – 30 mm thick for the ledges.
The radial artery passes through the first space from the back of the hand into the palm, while the perforating branches arising from the deep palmar arch pass through each of the other spaces. Dorsal interossei are bipennate (feather-like) muscles found in the dorsal compartment of the hand. The prefix bi- means that they arise by two heads which converge to attach onto a central tendon, which gives them a shape of a feather. The dorsal interossei consist of four muscles numbered 1–4 from the lateral to the medial side.
TV stardom and supporting film roles
In addition to their main function, the dorsal interossei contribute to the flexion in the metacarpophalangeal (MCP) joints and extension in the proximal (PIP) and distal interphalangeal (DIP) joints. Compared to other muscles of the hand acting on these joints, the contribution of dorsal interossei here is rather negligible, but still important in terms of stabilization of these joints. The functions of the dorsal interossei are aided by the abductor pollicis brevis, which abducts https://www.facebook.com/BooksTimeInc/ the thumb, and the abductor digiti minimi, which abducts the little finger. Therefore, the palmar interossei act antagonistically to the palmar interossei muscles, since the latter brings the fingers towards the midline.
