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…
Hip abduction is a movement that involves lifting the leg away from the body's midline, strengthening the outer hips, glutes, and thighs. It improves hip stability, balance, and overall lower…
Introduction The proximal tibiofibular joint is a synovial joint located between the lateral condyle of the tibia and the head of the fibula. It plays a key role in stabilizing…
The distal tibiofibular joint is the articulation between the lower ends of the tibia and fibula, located just above the ankle. It is a fibrous syndesmosis joint, meaning it is…
The sacroiliac (SI) joint joins the sacrum at the base of the spine to the pelvic ilium by the sacroiliac (SI) joint. It plays a crucial role in transferring weight and force between the upper body and the lower…

Introduction Ulnar deviation is the movement of the hand toward the little finger (ulnar) side, facilitated by the flexor carpi ulnaris and extensor carpi ulnaris. These motions are essential for…
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…
The patellofemoral joint is a unique and complex structure composed of static (bones and ligaments) and dynamic (the neuromuscular system) elements. The patella is shaped like a triangle, having an inferiorly oriented tip. The primary articulating surfaces of the patellofemoral joint are the trochlea and the distal articulating surface…
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…
