Which of the following statements is false?

The posterior cruciate ligament prevents posterior displacement of the femur.

The synovial membrane produces fluid that lubricates and nourishes cartilage.

Fibrocartilaginous pads are found in all synovial joints to enhance stability.

The joint capsule encloses the synovial cavity and provides structural support.

None

The __________ joint allows __________ movements, while the __________ joint permits rotational movement.

Saddle; sliding; plane

Ball-and-socket; biaxial; ellipsoid

Plane; rotational; hinge

Hinge; uniaxial; pivot

None

What characteristic of hyaline cartilage allows it to facilitate frictionless movement in synovial joints?

Its elasticity and ability to stretch

Its role in producing synovial fluid

Its high collagen content and smooth surface

Its vascular nature, which promotes lubrication

None

What would happen if the synovial membrane stopped functioning?

The joint capsule would thicken, reducing mobility.

The ligaments surrounding the joint would weaken.

Synovial fluid production would cease, leading to increased friction and cartilage damage.

The joint would lose its structural support, causing dislocation.

None

How does the joint capsule adapt in areas requiring greater mobility?

By secreting extra synovial fluid for lubrication.

By increasing the thickness of fibrocartilage.

By fusing with surrounding muscles.

By loosening its structure to allow movement.

None

Which intracapsular ligament of the knee attaches to the posterior tibia and the anterior femur?

Posterior cruciate ligament (PCL)

Lateral collateral ligament (LCL)

Anterior cruciate ligament (ACL)

Medial collateral ligament (MCL)

None

Which of the following statements is false?

The medial collateral ligament (MCL) restricts adduction of the knee joint.

Hyaline cartilage covers the articulating surfaces in synovial joints to reduce friction.

The synovial membrane produces synovial fluid to lubricate the joint.

Ball-and-socket joints allow for circumduction and rotation.

None

Which feature allows the shoulder joint (glenohumeral joint) to have a greater range of motion compared to the hip joint?

A greater number of intracapsular ligaments

A deeper bony congruence in the socket

Stronger surrounding ligaments

A loose joint capsule and shallow articulating surfaces

None

What are capsular ligaments?

Structures that produce synovial fluid

Ligaments that attach muscles to bones

Bands of dense connective tissue located inside the joint cavity

Thickenings of the joint capsule that provide additional support

None

10.

What is a key difference between the outer and inner layers of the joint capsule?

The outer layer contains blood vessels, while the inner layer is avascular.

The outer layer provides structural support, while the inner layer secretes synovial fluid.

The outer layer reduces friction, while the inner layer strengthens the joint.

The outer layer secretes synovial fluid, while the inner layer resists tension.

None
