Ch 6 Skeletal System Review

Where are irregular bones found?

• Skull
• Vertebrae
• Arms
• Wrist

The skeletal system consists of two main types of connective tissue:

• Cartilage
• Epithelium
• Bone
• Meninges

What are the two types of bone tissue?

• Spongy/Cancellous

• Short/stout

• Compact/Cortical

• Big

The basic structural unit of compact bone is

• a lacunae.
• an osteon.
• a canaliculi.
• a lamellae.

Which type of cell assists with the regulation of blood levels of calcium and phosphate by breaking down bone tissue?

• Osteoclasts
• Osteocytes
• Osteoblasts
• Fibroblasts
• False

Which type of bone cell helps form bone, specifically the bone’s matrix?

• Osteoclasts
• Osteoblasts
• Osteocytes
• Fibroblasts

Trabeculae are arranged along the lines of greatest stress in a way that offers maximum strength. If the stress a bone is exposed to changes, they will realign themselves to compensate.

• True
• False

Which statement correctly describes the periosteum?

• B, C, and D
• A. The periosteum secretes a lubricating fluid that eases bone movement.

• B. The periosteum contains blood vessels, making it crucial to bone survival.

• C. The periosteum contains bone-forming cells.

• D. The periosteum contains fibers that combine with the fibers of tendons.

Which classification of bone protects organs or provides a large surface area for the attachment of muscles?

• Long bones
• Short bones
• Flat bones
• Irregular bones

What makes bone unique from other connective tissue?

• It is nonliving tissue.
• Its matrix is hard and calcified.
• It doesn’t contain blood vessels.
• It is self-contained and doesn’t interact with other body systems.
