The lateral cutaneous nerve of forearm (or lateral antebrachial cutaneous nerve) is a sensory nerve representing the continuation of the musculocutaneous nerve beyond the lateral edge of the tendon of the biceps brachii muscle. The lateral cutaneous nerve provides sensory innervation to the skin of the lateral forearm.
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.
Axillary nerve (blue). Also Superior lateral cutaneous nerve of arm. Inferior lateral cutaneous nerve of arm - Near blue "axillary" area, but actually branches from radial nerve. Most modern sources distinguish the superior and inferior, but some still include a single "lateral brachial cutaneous nerve". ) Intercostobrachial nerve (brown)
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]
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]
In human anatomy, cutaneous nerves are primarily responsible for providing cutaneous innervation, sensory innervation to the skin.In addition to sympathetic and autonomic afferent (sensory) fibers, most cutaneous nerves also contain sympathetic efferent (visceromotor) fibers, which innervate cutaneous blood vessels, sweat glands, and the arrector pilli muscles of hair follicles.
