The Anatomy and Function of the Ulnar Nerve: Insights into Diagnosis and Treatment of Ulnar Neuropathy and Related Conditions

Abstract

Rachel Keeffe

The human ulnar nerve is one of the major nerves in the upper extremity, responsible for providing motor and sensory innervation to the hand and forearm. It originates from the brachial plexus, a network of nerves that emerge from the spinal cord in the neck. From there, it travels down the arm, passing through several important structures such as the axilla, the medial side of the upper arm, and the elbow joint.
