Introduction: A nerve entrapment occurs when a peripheral nerve loses mobility, and flexibility, or is squeezed by surrounding tissues. A nerve entrapment can result in neuropathic/neurogenic pain, which can be…
Introduction The brachial plexus is a network of nerves that originates from the spinal cord in the neck (C5 to T1 nerve roots) and extends through the shoulder to control…
Introduction The dorsal scapular nerve originates from the root of spinal nerve C5, which is one of the brachial plexus's lateral branches. On rare occasions, it could originate from the…
Introduction The medial antebrachial cutaneous nerve is a sensory nerve originating from the medial cord of the brachial plexus, primarily carrying fibers from the C8 and T1 nerve roots. It…
Introduction The medial pectoral nerve arises from the medial cord of the brachial plexus (C8-T1). It primarily innervates the pectoralis major (sternocostal head) and pectoralis minor muscles. Unlike the lateral…
Introduction The Anterior Interosseous Nerve (AIN) is a branch of the median nerve that arises in the forearm. It supplies the flexor pollicis longus (FPL), the lateral half of the…
Introduction The long thoracic nerve arises from the C5-C7 nerve roots and innervates the serratus anterior muscle. It plays a crucial role in scapular stability, preventing winging of the shoulder…
The coccygeal nerve is the 31st and final spinal nerve, arising from the coccygeal region of the spinal cord. It primarily contributes to the coccygeal plexus, which provides sensory innervation…
Introduction The inferior gluteal nerve is also a motor branch of the sacral plexus, coming from the posterior divisions of the L5, S1, and S2 anterior roots. It flows inferiorly…
Introduction The superior gluteal nerve, a motor branch of the sacral plexus, originates from the posterior divisions of the L4, L5, and S1 anterior roots. The superior gluteal nerve and…
