Question 20

The anatomy of a diaphysis

Answer 20

The shaft of a long bone

Question 21

The anatomy of a epiphysis

Answer 21

The ends of a bone

Question 22

The anatomy of a metahysis

Answer 22

Where the Diaphysis joins epiphysis

Question 23

The anatomy of a epiphyseal plate

Answer 23

A layer of hyaline cartilage that allows the diapjysis of the bone to grow in length

Question 24

The anatomy of a articular cartilage

Answer 24

Covers epiphysis and reduces shock and friction

Question 25

Nutrient foremen

Answer 25

Allows artery and vein to enter the bone

Question 26

The anatomy of a periosteum

Answer 26

Tough sheath of connective tissue that surrounds the bone surface. It contains bone forming cells allowing bone to grow in diameter not length.

Question 27

The anatomy of a medullary cavity

Answer 27

Contains the bone marrow

Bone forming cells

Question 30

Explain osteocytes

Answer 30

Mature bone cells

Question 31

Explain osteoclasts

Answer 31

Cells that break down (resort) bone matrix

Question 32

Explain a compact bone

Answer 32

Does not have visible spaces in bone matrix, forms thick walled diaphysis

Question 33

Explain spongey bone

Answer 33

Consists of delicate sheets of bone | End of long bones

Question 34

How does bone formation occur

Answer 34

Intranenbranous ossification - Bone forms directly within mesenchyme - within fibrous tissues - flat bones of the skull and the mandible Endochondral ossification -Bone forms within hyaline cartilage that develops from the mesenchyme. (Most bones are former this way.
