The ulnar nerve enters the hand underneath the superficial part of the flexor retinaculum (in Guyon’s canal) and then it divides in the deep and superficial branches. The deep department is mainly motor and provides the hypothenar, interossei and medial two lumbricals muscles. The superficial branch is mainly sensory but additionally innervates the palmaris brevis muscle; it offers palmar and dorsal cutaneous innervation on the very little finger and medial fifty percent of the ring finger. Examine idea: The ulnar nerve innervates all intrinsic muscles apart from the LOAF: Lateral two lumbricals, Opponens pollicis, Abductor pollicis brevis, Flexor pollicis brevis with supply by the median nerve.

The 4 fingers Just about every consist of three phalanx bones: proximal, middle, and distal. The thumb only consists of a proximal and distal phalanx.[11] Together with the phalanges of the fingers and thumb these metacarpal bones variety five rays or poly-articulated chains.
The palm connects on the fingers by means of adaptable joints, allowing for it to fold and aid hand motion.
