The ulnar nerve runs along the ulna bone in the arm. It starts at the shoulder and ends at the pinky finger.
"In human anatomy, the ulnar nerve is a nerve which runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve." -

The ulnar groove also known as the ulnar sulcus is a slight depression found at the inferior, posterior, medial side of the humerus bone. The ulnar nerve runs downwards in the ulnar groove to go to the ulna.

Striking the "funny bone" is actually stimulating the ulnar nerve, which runs from the neck down to the hand. When the ulnar nerve is accidentally hit or compressed, it can cause a tingling sensation and discomfort in the elbow, forearm, and hand.

The nerve in the medial epicondyle that can cause tingling in the hand is the ulnar nerve. Compression or injury to the ulnar nerve at the elbow can lead to symptoms like tingling, numbness, and weakness in the hand and fingers.
Shoulder impingement typically does not directly cause ulnar nerve damage. However, if left untreated, shoulder impingement can lead to altered mechanics and postures which may put additional stress on the ulnar nerve over time, potentially leading to issues like ulnar nerve entrapment. It's important to address shoulder impingement early to prevent complications.
Ulnar neuritis is inflammation of the ulnar nerve, while ulnar neuropathy refers to damage or dysfunction of the ulnar nerve. Neuritis is usually reversible with treatment, while neuropathy may result in more permanent nerve damage. Symptoms of neuritis may include pain, tingling, and weakness, while neuropathy can cause more severe symptoms like muscle wasting and loss of sensation.
Most commonly, trauma to the elbow or repetitive bending of the elbow puts pressure on the ulnar nerve that damages the myelin sheath insulating and protecting the nerve.
You have three nerves, which supply your forearm. Radial, ulnar and median nerve. Out of these three nerves, median nerve is the main nerve to supply forearm muscles and some of the hand muscles.
