APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The hypothenar muscle group is formed by three muscles: the abductor digiti minimi, the flexor digiti minimi, and the opponens digiti minimi. They form the muscle bulk on the small finger side of the hand. The abductor allows the small finger to pull away from the ring finger.

Detailed explanation-2: -The interossei muscles are intrinsic muscles of the hand located between the metacarpals. They consist of four (or three) palmar and four dorsal muscles that, respectively. These muscles are responsible for finger adduction and abduction.

Detailed explanation-3: -The Abductor pollicis longus (APL) is one of a deep extensor of the forearm and is responsible for facilitating movement and stabilization of the thumb. Its tendon is present in the first extensor compartment of the wrist. It lies immediately below the supinator and sometimes unites with it.

Detailed explanation-4: -In the hand, adductors draw the fingers together. Also known as ductless glands; release secretions called hormones directly into the bloodstream which in turn influence the welfare of the entire body.
