The Course of N.ulnaris


A short article on the course of ulnar nerve.

A link to the article: The Course of N.ulnaris – click here

The ulnar nerve (C7, 8, T1) is the continuation of the medial cord of the brachial plexus. It is usually joined in the axilla by fibers from C7. The ulnar nerve is motor to most of the small muscles of the hand, to flexor carpi ulnaris, and to the ulnar half of the flexor digitorum profundus. It provides sensibility to the ulnar aspect of the hand.

The Innervation of the Upper Limb


I have written this short segment about the innervation of the upper extremity, just as a reference to the nerves, their origin, course and what they innervate.

Link to an article, click here.

The upper extremity receives neural branches from various spinal nerves. Mostly is innervated by Brachial plexus (C5-T1), but also from Cervical plexus (C3-C4) and intercostal nerve.
