The superficial branch of the ulnar nerve is a terminal branch of the ulnar nerve. [1] It supplies the palmaris brevis and the skin on the ulnar side of the hand. [2] [3] It also divides into a common palmar digital nerve and a proper palmar digital nerve.
Branches of the ulnar nerve in hand. Ulnar nerve enters the palm of the hand via the Guyon's canal, superficial to the flexor retinaculum and lateral to the pisiform bone. [7] Here it gives off the following branches: [8] Superficial branch of ulnar nerve - supplies the palmaris brevis and gives digital branches to the medial one and a half ...
The palmar branch of the ulnar nerve arises about five cm proximal to the wrist from where the ulnar nerve splits into palmar and dorsal branches. It supplies sensory innervation to a small area in the palmar surface of the wrist. The palmar branch represents the continuation of the ulnar nerve as it crosses the flexor retinaculum of the hand ...
Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.
The proper palmar digital nerves of the ulnar nerve are nerves of the hand.. The superficial branch of the ulnar nerve divides into a proper palmar digital nerve, which supplies the medial side of the fifth digit and a common palmar digital nerve which divides into two proper palmar digital nerves that supply the adjacent sides of the fourth and fifth digits.
The common palmar digital nerves of the ulnar nerve are nerves of the hand. The nerve branches off the superficial branch of the ulnar nerve and runs toward the cleft between the ring and little fingers. [1]
The third and fourth lumbricals (most ulnar two) are innervated by the deep branch of ulnar nerve. [5] This is the usual innervation of the lumbricals (occurring in 60% of individuals). However 1:3 (median:ulnar - 20% of individuals) and 3:1 (median:ulnar - 20% of individuals) also exist.
The superficial head is usually innervated by the recurrent branch of the median nerve. [5] The deep part is often innervated by the deep branch of ulnar nerve (C8 and T1 roots). [6] [7] There are normal variations. In a Cannieu-Riche anastomosis, fibers from the deep branch of ulnar nerve innervate the opponens pollicis and/or abductor ...
