Anatomy of the knee A. The knee joint has four main ligaments which are responsible for it being stabile. The main ligaments are 1. Anterior Cruciate Ligament (ACL) 2. Posterior Cruciate Ligament (PCL) 3. Medial Collateral Ligament (MCL) 4. Lateral Collateral Ligament (LCL) III. What is Runners knee? A. Runner’s knee is a common among runners. But it can also happen to any athlete who does activities that involve

collateral ligaments have a stabilizing effect in a lateral plane of motion‚ helping to prevent sideward displacement and over-rotation. The medial collateral attaches the femur to the tibia‚ also attaching to the medial meniscus. The lateral collateral attaches the femur to the fibula but has no attachment to the lateral meniscus. Both collaterals lie slightly posterior to the lateral axis of the knee joint and are taut when the knee is full extension. This positioning of the ligaments causes

mechanical causes of back pain include spasms‚ muscle tension‚ and ruptured discs‚ which are also called herniated discs. Injuries: Spine injuries such as sprains and fractures can cause either short-lived or chronic back pain. Sprains are tears in the ligaments that support the spine‚ and they can occur from twisting or lifting improperly. Fractured vertebrae are often the result of osteoporosis‚ a condition that causes weak‚ porous bones. Less commonly‚ back pain may be caused by more severe injuries that

These four types of collagen are found in over 90 percent of the body in tissues and structures including the skin‚ bones‚ tendons and ligaments.

In this exercise I will exam how joints function and thereby discover how they allow for movement in the body. Joints are where two bones come together. The joints hold the bones together and allow for movement of the skeleton. All of the bones‚ except the hyoid bone in the neck‚ form a joint. Joints

Less often‚ the ankle rolls inward and the foot turns outward. This damages the ligaments on the inside of the ankle. An ankle sprain can range from mild to severe‚ depending on how badly the ligament is damaged and how many ligaments are injured. With a mild sprain‚ the ankle may be tender‚ swollen‚ and stiff. But it usually feels stable

If the ligaments do not become more pliable then they would snap under the force of the contractions of the person’s muscles. They increase in pliability due to fibroblasts in the collagen of the ligaments which secret proteins that allow for a more pliable ligament. It is important for the ligaments to become more pliable as they would snap under the force of contractions if they didn’t adapt. The ligaments will therefore bend and not snap under the power
