Suprascapular Nerve

Introduction The suprascapular nerve is a branch of the brachial plexus (C5-C6) that supplies motor innervation to the supraspinatus and infraspinatus muscles, which are key for shoulder movement and stability. It also carries sensory fibers to the glenohumeral joint and surrounding ligaments. The nerve passes through the suprascapular notch, where it is susceptible to compression…

Common Peroneal Nerve

Introduction The common peroneal nerve (also known as the common fibular nerve) is a branch of the sciatic nerve, originating in the lumbosacral plexus (L4-S2). It wraps around the head of the fibula, making it vulnerable to injury. The nerve then divides into the superficial and deep peroneal nerves, innervating the lateral and anterior compartments…

Obturator Nerve

Introduction The obturator nerve is a peripheral nerve that arises from the lumbar plexus (L2-L4) and primarily supplies the medial thigh. It provides motor innervation to the adductor muscles (adductor longus, adductor brevis, adductor magnus, gracilis, and obturator externus) and sensory innervation to the skin of the medial thigh. In several pathologic disorders and operations…

Femoral Nerve

Introduction The femoral nerve is a major peripheral nerve of the lower limb, originating from the lumbar plexus (L2-L4). It supplies motor innervation to the anterior thigh muscles (e.g., quadriceps) responsible for knee extension and hip flexion, and provides sensory innervation to the anterior thigh and medial leg via the saphenous nerve. It plays a…

Guyon Canal Syndrome (Ulnar tunnel syndrome)

What is a Guyon Canal Syndrome? Guyon’s Canal Syndrome, also known as Ulnar Tunnel Syndrome, is a condition caused by compression of the ulnar nerve as it passes through Guyon’s canal in the wrist. It can result from repetitive wrist motions, prolonged pressure, or trauma. Symptoms include numbness, tingling, weakness, and pain in the ring…

Ulnar Nerve

Introduction The ulnar nerve is a major peripheral nerve that runs from the neck down to the hand, playing a crucial role in movement and sensation. It controls fine motor functions in the hand and provides sensation to the ring and little fingers. Often referred to as the “funny bone” nerve, it is vulnerable to…

Median Nerve

The median nerve is a major nerve of the upper limb, originating from the brachial plexus (C5-T1). It runs down the arm, forearm, and into the hand, providing motor innervation to most forearm flexor muscles and some hand muscles, and sensory innervation to the lateral palm, thumb, index, middle, and half of the ring finger….

List of the Nerves of the Human Body

The human nervous system consists of a vast network of nerves that transmit signals between the brain, spinal cord, and the rest of the body. These nerves are classified into: This system ensures communication and coordination throughout the body. What are Nerves? Nerves function like cables, carrying electrical impulses between your brain and the rest…
