The Ulnar nerve is located in the joint of the elbow. It is the largest unprotected nerve in the human body, therefore injuries are very common. It is also commonly referred to as the "Funny Bone".
The nerves issuing from the Brachial plexus in order from anterior to posterior are musculocutaneous nerve, median nerve, ulnar nerve, radial nerve, and axillary nerve.
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.
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
The median nerve is a member of the brachial plexus. It is formed by contributions from the lateral and medial cords of the brachial plexus, primarily from spinal nerve roots C6, C7, C8, and T1.
The nerve that control the larynx during breathing is the Vagus Nerve.
Ulnar nerve
The ulnar and median nerves arise from the brachial plexus. Specifically, the median nerve is formed from contributions of the lateral and medial cords of the brachial plexus, while the ulnar nerve primarily arises from the medial cord. Both nerves are crucial for motor and sensory functions in the arm and hand.

From the brain to the spinal cord through the brachial plexus to the ulnar nerve to the pinky finger.
The ulnar nerve does not directly connect to a specific part of the brain. Instead, it originates from the brachial plexus, which is a network of nerves in the neck and shoulder region, and it innervates muscles in the forearm and hand. Sensory information from areas innervated by the ulnar nerve is transmitted to the spinal cord and then relayed to the brain for processing, primarily involving the sensory cortex.

"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 largest branch of the sacral plexus is the sciatic nerve, the thickest and longest nerve in the body.
