Why does DFCT heal slowly after an injury?

It contains no collagen fibers to support repair.

It is avascular, relying on limited nutrient diffusion.

It undergoes calcification during healing, slowing the process.

It lacks fibroblasts, which are necessary for tissue regeneration.

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 cartilage may fail to calcify.

Bone density may increase or decrease abnormally.

None

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

Its high water content in the matrix

Its dense collagen bundles

Its avascular nature

Its elastin fibers

None

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

Both are primarily found in growth plates.

Both contain chondrocytes housed in lacunae.

Both create smooth, frictionless surfaces for movement.

Both are highly vascular and repair quickly.

None

The three main components of a joint are __________, __________, and __________.

Osteoblasts; Chondrocytes; Growth plates

Synovial fluid; Fibrous capsule; Cartilage

Bones; Cartilage; Soft tissues

Muscles; Tendons; Ligaments

None

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

To facilitate growth in the medullary cavity

To cushion bones and absorb shock in joints

To connect muscle to bone and allow movement

To resist tension and stabilize joints

None

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

To act as a shock absorber and distribute force.

To ossify and strengthen the joint over time.

To connect muscles to bones for stabilization.

To protect the joint by creating frictionless movement.

None

What is the role of lacunae in cartilage?

They allow diffusion of nutrients directly into cartilage.

They house chondrocytes that maintain the cartilage matrix.

They connect cartilage to tendons and ligaments.

They act as shock absorbers in fibrocartilage.

None

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

Synovial; Fibrous

Elastic; Dense connective tissue

Hyaline; Fibrocartilage

Fibrocartilage; Ligaments

None

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

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

Hyaline cartilage is vascular, while fibrocartilage is not.

None
