Bones; Cartilage; Soft tissues

Osteoblasts; Chondrocytes; Growth plates

None

The two types of cartilage found in joints are __________ cartilage and __________ cartilage.

Elastic; Dense connective tissue

Hyaline; Fibrocartilage

Fibrocartilage; Ligaments

Synovial; Fibrous

None

What is the primary function of fibrocartilage in high-stress joints?

To ossify and strengthen the joint over time.

To act as a shock absorber and distribute force.

To protect the joint by creating frictionless movement.

To connect muscles to bones for stabilization.

None

What is the role of lacunae in cartilage?

They act as shock absorbers in fibrocartilage.

They allow diffusion of nutrients directly into cartilage.

They connect cartilage to tendons and ligaments.

They house chondrocytes that maintain the cartilage matrix.

None

What structural difference between hyaline cartilage and fibrocartilage allows them to serve different functions in joints?

Hyaline cartilage has dense collagen bundles, while fibrocartilage does not.

Fibrocartilage has dense collagen bundles, while hyaline cartilage has sparse fibers.

Fibrocartilage has high water content, while hyaline cartilage has none.

Hyaline cartilage is vascular, while fibrocartilage is not.

None

What is the primary role of dense fibrous connective tissue (DFCT) in ligaments?

To connect muscle to bone and allow movement

To cushion bones and absorb shock in joints

To resist tension and stabilize joints

To facilitate growth in the medullary cavity

None

What happens if the balance between osteoblast and osteoclast activity is disrupted?

The medullary cavity may shrink entirely.

Bones may grow longer but not wider.

Bone density may increase or decrease abnormally.

Bone cartilage may fail to calcify.

None

What structural feature of hyaline cartilage contributes to its ability to resist compression?

Its avascular nature

Its high water content in the matrix

Its dense collagen bundles

Its elastin fibers

None

Which of the following is a similarity between hyaline cartilage and fibrocartilage?

Both contain chondrocytes housed in lacunae.

Both are highly vascular and repair quickly.

Both create smooth, frictionless surfaces for movement.

Both are primarily found in growth plates.

None

10.

Why does DFCT heal slowly after an injury?

It contains no collagen fibers to support repair.

It lacks fibroblasts, which are necessary for tissue regeneration.

It undergoes calcification during healing, slowing the process.

It is avascular, relying on limited nutrient diffusion.

None
