Skeletal System Unit Review

Which of the following is NOT a function of the skeletal system?

• Support

• Protection

• Movement

• Hormone Regulation

• Storage

Bones are a solid matrix made up of:

• living cells & fibers, surrounded by calcium deposits

• at least 3 different types of tissues serving a common purpose

• only calcium and other mineral salts responsible for hardness & strength

• multiple different types of cartilage

This internal cartilage found between the diaphysis & epiphyses of long bones is responsible for growth regulation:

• articular cartilage

• diaphysis plate

• epiphyseal plate

• calcitonin

The ends of epiphyses are covered with this layer, responsible for smooth movement of joints & cushion from shock:

• epiphyseal plate

• synovial fluid

• articular cartilage

• yellow bone marrow

For a bone marrow transplant, surgeons would have to drill a needle into this portion of the bone:

• epiphysis

• spongy bone

• periosteum

• medullary cavity

Within the bone marrow, new blood cells are produced in a process called:

• erythrocytosis

• osteoblasts

• hematopoiesis

• osteogenesis

This outer layer of bone is the site of muscle attachment and bone repair:

• spongy bone

• periosteum

• canaliculi

• compact bone

The following image shows what type of bone?

• compact bone

• bone marrow

• spongy bone

• osteons

Spongy bone is made up of trabeculae found along lines of stress. Its purpose is:

• to provide an attachment point for muscles

• provide strength & hardness to bone

• to connect bone cells, allowing them to receive nutrients & remove wastes

• to provide perfect resistance from compression

Compact bone is arranged in:

• a lattice of trabeculae

• cylinders called osteons

• layers of periosteum

• hollow canals
