The ulnar nerve is a major peripheral nerve that plays a crucial role in the functioning of the upper limbs. It originates from the brachial plexus, a network of nerves formed by the lower cervical and upper thoracic spinal nerves. The ulnar nerve travels down the arm, passing through the cubital tunnel at the elbow and continuing into the forearm. Along its course, the ulnar nerve supplies sensation to the little finger and half of the ring finger, as well as controls the muscles responsible for finger and wrist movements. Understanding the anatomy of the ulnar nerve is vital in assessing its function and determining any possible sites of compression or tension. By performing the ulnar nerve tension test, clinicians can effectively evaluate the integrity and mobility of the ulnar nerve, aiding in the diagnosis and treatment of various conditions affecting this important neural pathway.
The ulnar nerve is a major nerve located within the upper limb of the body. It runs along the inner aspect of the arm, originating from the brachial plexus in the neck. The nerve then travels downwards, passing through the axilla (armpit) and along the medial aspect of the upper arm.
As it continues its course, the ulnar nerve passes through a tunnel called the cubital tunnel, located on the posterior aspect of the elbow. This tunnel is formed by the bone and ligaments of the elbow joint. Once the ulnar nerve exits the cubital tunnel, it travels along the forearm and finally innervates the muscles and skin of the hand.
In the upper limb, the ulnar nerve runs parallel to other major nerves, such as the median nerve and the radial nerve. These nerves collectively provide motor and sensory innervation to the upper limb. The ulnar nerve specifically supplies the muscles that control movement and sensation of the little and ring fingers.
Understanding the location and pathway of the ulnar nerve is crucial in diagnosing and treating conditions related to nerve tension or compression. Conditions such as ulnar nerve entrapment or cubital tunnel syndrome can cause pain, numbness, and weakness in the affected arm and hand.

The ulnar nerve is a major peripheral nerve in the upper limb that plays a crucial role in sensory and motor functions. It originates from the medial cord of the brachial plexus, which is a network of nerves in the shoulder region. The ulnar nerve runs down the arm and passes through several anatomical landmarks.
Starting in the axilla, the ulnar nerve travels along the posterior aspect of the arm, running parallel to the brachial artery. At the medial epicondyle of the humerus, it enters a groove called the cubital tunnel, an important anatomical landmark. Here, the nerve can sometimes be vulnerable to compression or irritation, leading to symptoms such as pain, tingling, and weakness. From the cubital tunnel, the ulnar nerve continues its course under the flexor carpi ulnaris muscle and along the ulnar side of the forearm.
In the wrist, the ulnar nerve gives off a branch called the deep branch, which innervates the muscles of the hand, including the intrinsic muscles responsible for fine finger movements. The main trunk of the ulnar nerve then continues into the palm of the hand, supplying sensation to the ulnar side of the hand, including the little finger and part of the ring finger.
It is important to note that there may be variations in the anatomical course and composition of the ulnar nerve among individuals. These variations can impact the potential for nerve compression or injury. Healthcare professionals must be aware of these variations when performing ulnar nerve tension tests and other diagnostic procedures.
In summary, the ulnar nerve is a critical nerve that runs from the upper arm to the hand, supplying both motor and sensory functions. Understanding its structure, anatomical course, and relationship to important landmarks is essential for diagnosing and treating conditions that affect the ulnar nerve.
