Introduction The cervical plexus is a collection of cervical nerves created by the anterior (ventral) rami of spinal nerves C1-C4 (sometimes known as the first through fourth cervical nerves). The cervical plexus’ roots (limbs) are shown here. The 5th cervical nerve (the anterior ramus of spinal nerve C5) may also be regarded as a member…
Introduction The Medial Collateral Ligament (MCL) is a band of tissue located on the inner side of the knee, connecting the femur (thigh bone) to the tibia (shin bone). It provides stability by preventing excessive inward movement of the knee joint. MCL injuries can range from minor sprains to full tears and can be caused…
Introduction The sacral plexus is a neural network made up of the lumbosacral trunk (L4, L5) and the sacral spinal nerves (S1–S4). The sacral plexus is situated on the posterior pelvic wall, behind the internal iliac arteries and ureter, and ahead of the piriformis muscle. The plexus has multiple branches, including anterior, posterior, and one…
Introduction The lumbar plexus is a neural network formed by the anterior rami of spinal nerves L1 through L4 and the anterior ramus of spinal nerve T12. It is situated on the posterior abdominal wall, anterior to the transverse processes of the lumbar vertebrae, and inside the posterior section of the psoas major muscle. The…
Introduction The ulnar collateral ligament (UCL) is a strong band of tissue located on the inner side of the elbow, connecting the humerus (upper arm bone) to the ulna (one of the forearm bones). It provides stability to the elbow joint, particularly during activities involving throwing or overhead motions. UCL injuries are common in athletes,…
Hip External Rotation Hip external rotation refers to the movement of the thigh or leg rotating outward, away from the body’s midline. This motion is essential for activities like walking, running, and maintaining balance. It involves muscles such as the piriformis, gluteus maximus, and other deep hip rotators. What are the hip’s internal and external…
Introduction: Dealing with degenerative disc disease in the neck can be painful and frustrating. I faced constant discomfort, limited mobility, and the fear that it might only get worse. But through a combination of targeted exercises, posture corrections, and lifestyle changes, I found relief and regained my quality of life. In this video, I’ll share…
Introduction: The glenohumeral ligaments are a group of three ligaments (superior, middle, and inferior) that reinforce the shoulder joint, connecting the humerus to the glenoid cavity of the scapula. They provide stability by limiting excessive movement and preventing dislocation, particularly during shoulder rotation and abduction. They are also in charge of preventing the humerus bone…
The Lateral Collateral Ligament (LCL) is a key stabilizer of the knee joint, located on the outer side. It connects the femur (thigh bone) to the fibula (the smaller bone of the lower leg) and provides stability by preventing excessive side-to-side movement. Injuries to the LCL often occur due to direct impact or excessive stress…
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 acute or chronic. Nerve entrapment syndromes (meaning a shared set of signs and symptoms) are caused by swelling of the surrounding tissues or structural defects….
