Question

Two ____ are also found within the joint cavity. Consisting of fibrocartilage, these structures separate and align the femoral and tibial joint surfaces. The knee joint involves a ____ joint between the condyles of the femur and the condyles of the ____. It also involves a ____ joint between the femur and patella. Within the joint cavity are the two ____ ligaments that help to prevent displacement of the joint surfaces, crossing each other as they run from tibia to femur. Tendons and several ligaments stabilize this joint. For example, from the inferior margin of the patella to the tibial ____ is the patellar ligament. The tibial and fibular ____ ligaments run on either side of the joint capsule. Two ____ ligaments run from the lateral condyle of the femur to the heads of the tibia and fibula. collateral condylar cruciate epicondyle menisci modified hinge plane popliteal tendons tibia tuberosity

Explanation / Answer

1. Menisci

The menisci are fibrocartilagenous in nature and they are present in the joint cavity.

2.a) Modified hinge joint,

b)Tibia,

c)Plane(not confirmed)

The knee joint consists of two joints- tibiofemoral and patellofemoral joints.

3. Cruciate ligaments-

he cruciate ligaments of the knee are the anterior cruciate ligament (ACL) and the posterior cruciate ligament(PCL). These ligaments are two strong, rounded bands that extend from the head of the tibia. They cross each other forming the letter X. Stabilise the knee joint

4. Tuberosity

5. a) Collateral

The tibial and fibular collateral ligaments are also called medial and lateral collateral lifaments, respectively. They run on either side of the capsule of the knee joint.

b) Condylar(not confirmed)
