Document Summary

Attachments = flexor retinaculum proximal phalanx of mc 5. Its movements include abduction of the little finger. Attachments = proximal phalanx of the mc 5. It has responsibility to flex the little inger. Attachments = flexor retinaculum metacarpal of the little finger. Is responsible for rotation of the little finger medially. These muscles are found at the digits and arise from the tendons and arise from the tendons of flexor digitorum profundus. They flex the metacarphalphalangeal joints and extend the proximal and distal interphalangeal joints. They are innovated by the ulna and median nerve based on position. Attachments = shafts of metacarpals the proximal phalanx and dorsal digital expansion. They are responsible for abducting the fingers and adduct the middle finger when abducted. Attachments = shaft of the metacarpals proximal phalynx and dorsal digital expansions. Attachments = metacarpals 2 & 3 the proximal phalynx of the thumb.
