The ulnar nerve is one of the major nerves of the arm, primarily responsible for controlling the muscles of the forearm and hand. It innervates the intrinsic muscles of the hand, particularly those responsible for fine motor skills, as well as some muscles in the forearm. Its sensory function includes providing sensation to the skin of the little finger and half of the ring finger. Damage to the ulnar nerve can result in weakness, numbness, or tingling in these areas, often referred to as "cubital tunnel syndrome."

Symptoms of neuritis may include pain, tingling, and weakness, while neuropathy can cause more severe symptoms like muscle wasting and loss of sensation.

Ulnar nerve test for loss of function?
Ulnar nerve typically supplies the intrinsic muscles of the hand. Hence the tests for ulnar nerve are based on the functions performed by these muscles. The intrinsic muscles or interossei are concerned with gripping function of the fingers. So things like holding a card or cigarette between 2 fingers is with the help of these muscles. A generalized loss of coordination of hands causing clumsy hands is often seen with ulnar nerve diseases or palsy. Tests like, froment's sign, card test, and so on, are used for evaluation of ulnar nerve injury.
