The dorsal branch (ramus dorsalis; posterior branch) descends, along the dorsal surface of the radial side of the forearm to the wrist.. It supplies the skin of the lower two-thirds of the dorso-lateral surface of the forearm, communicating with the superficial branch of the radial nerve and the posterior cutaneous nerve of forearm of the radial nerve.
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.
Lower limb. Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves, but there are minor variations in some of the details.
The superior lateral cutaneous nerve of arm (or superior lateral brachial cutaneous nerve) is the continuation of the posterior branch of the axillary nerve, after it pierces the deep fascia. It contains axons from C5-C6 ventral rami.
It provides sensory innervation to the lateral forearm (via its terminal branch). [3] It courses through the anterior part of the arm, terminating 2 cm above elbow; [citation needed] after passing the lateral edge of the tendon of biceps brachii it is becomes known as the lateral cutaneous nerve of the forearm. [3]
The inferior lateral cutaneous nerve of arm is a nerve found in humans and other animals. It is also called the inferior lateral brachial cutaneous nerve. It is a branch of the radial nerve that provides sensory and vasomotor innervation to the lower, lateral aspect of the arm. [1]
The lower branch pierces the deep fascia below the insertion of the deltoideus, and descends along the lateral side of the arm and elbow, and then along the back of the forearm to the wrist, supplying the skin in its course, and joining, near its termination, with the dorsal branch of the lateral antebrachial cutaneous nerve.
Another branch observed, that is mentioned in passing in previous literature is the medial branch of the lateral sural cutaneous nerve. [3]In a 2021 study by Steele et al. (Annals of Anatomy), a medial branch of the lateral sural cutaneous nerve was observed in approximately 36% of lower extremities dissected (n=208) with an average diameter of 1.47 ± 0.655 mm with a 95% CI of 1.31 – 1.625 mm.
