Which statement is tine concerning the knee joint? The lateral meniscus is an intrinsic ligament located on the lateral side of the knee joint. Hyperextension is resisted by the posterior cruciate ligament. The anterior cruciate ligament supports the knee when it is flexed and weight bearing. The medial meniscus is attached to the tibial collateral ligament.

A stiff neck due to spasmodic contraction of the neck muscles that pull the head toward the affected side is known as _________, or wryneck.

Watch this video (http://openstaxcollege.org/l/flexext) to learn more about the flexion and extension of the knee, as the femur both rolls and glides on the tibia to maintain stable contact between the bones in all knee positions. The patella glides along a groove on the anterior side of the distal femur. The collateral ligaments on the sides of the knee become tight in the fully extended position to help stabilize the knee. The posterior cruciate ligament supports the knee when flexed and the anterior cruciate ligament becomes tight when the knee comes into full extension to resist hyperextension. What are the ligaments that support the knee joint?
