ULNAR NERVURE Meaning and
Definition
-
The ulnar nervure, also known as the ulnar nerve, is a prominent nerve in the human body that runs from the shoulder down to the hand along the inner side of the arm. It is one of the major nerves of the upper extremity and is responsible for providing sensory and motor innervation to the forearm and hand.
Originating from the brachial plexus, the ulnar nervure courses through the upper arm, passing behind the medial epicondyle of the humerus bone before crossing the elbow joint. It then continues down the forearm along the ulnar bone, supplying sensory fibers to the skin on the medial side of the hand and the little finger, as well as the adjacent half of the ring finger. Additionally, the ulnar nervure innervates various muscles that control movements of the hand and fingers, such as the flexor carpi ulnaris, flexor digitorum profundus, and the intrinsic muscles of the hand.
Along its pathway, the ulnar nervure plays a crucial role in facilitating fine motor skills and dexterity, as well as providing a sense of touch and proprioception to the corresponding areas. It also participates in the coordination of finger movements and contributes to the overall strength and stability of the hand.
Injury or compression of the ulnar nervure can lead to a condition called ulnar neuropathy or ulnar nerve entrapment, which is characterized by symptoms like numbness, tingling, weakness, or pain in the hand, particularly in the little finger and ring finger. Treatment options for ulnar nerve compression may include conservative approaches such as physical therapy and splinting, or in severe cases, surgical intervention may be required to relieve the compression and restore proper nerve function.

Etymology of ULNAR NERVURE
The word "ulnar" is derived from the Latin word "ulna", meaning "forearm". It refers to the bone on the inner side of the forearm (known as the ulna bone). The term "nervure" comes from the Latin word "nervus", which means "nerve" or "sinew". Therefore, "ulnar nervure" is a term used in anatomy to describe a nerve located in the forearm region.
