Anatomy of the Bones

Question 1

Located both at proximal and distal ends of the bones

Answer 1

Epiphysis

Question 2

• Located at the epiphyseal cartilage
• Area between epiphysis and diaphysis
• Where bone lengthens in mature animals

Answer 2

Metaphysis (Growth plate)

Question 3

• Spongy bone
• A mesh-like porous network with spaces filled with bone marrow
• Helps with decreasing the weight of bone without decreasing strength

Answer 3

Cancellous

Question 4

• Hard superficial layer of bone

- Forms the shaft of the long bones and the outer layer of all bones

Answer 4

Compact or Cortical Bone

Question 5

• Space within the one axis of a long bone

- Filled with bone marrow

Answer 5

Medullar Cavity

Question 6

• Shaft of a long bone

- Divided into sections; proximal diaphysis/ mid-diaphysis/ Distal diaphysis

Answer 6

Diaphysis

Question 7

Lining of medullar cavity, has osteoblasts for bone production and or healing as needed

Answer 7

Endosteum

Question 8

• Thin membrane lining the outside surface of bone except the articular surface
• Contains osteoblasts to allow bone healing in fractures
• Enables bone to grow in diameter, sensitive to pain

Answer 8

Periosteum
