Summary Introduction

To review:

The deficit in motor and sensory inputs after an injury in the ulnar nerve.

Introduction:

The medial cord of the brachial plexus originates from the ulnar nerve. Ulnar nerve descends along with the medial side of the arm and gets continued till the hand. At the elbow region, ulnar nerve passes posterior to the medial epicondyle of the humerus bone. The intrinsic muscles of the hand and the skin on the medial side of the hand are innervated by the ulnar nerve.
