Bone Anatomy

Question 1

Types of bone

Answer 1

Cortical (compact)

Cancellous (spongy)

Question 2

Cortical Bone

Answer 2

(Lamellar)
Dense with tiny passage ways for nerves and blood vessels and lymph structures
Surface of bone, giving strength and structure
80% of bone mass
Surface good fixation point

Question 3

Osteons

Answer 3

Structural unit of the cortical bone
Reinforcing columns arranged around lines of stress
Central Haversian canal for blood vessels and nerves

Question 4

Cancellous Bone

Answer 4

Spongy with a high surface area
Less dense, weaker than cortical bone
Highly vascular and contains red bone marrow

Question 5

Periosteum

Answer 5

Fiberous connective tissue that covers outer surface on bone
Outer layer- fibroblasts that make connective tissues and blood vessels and fivers
Inner layer; osteoclasts and osteoblasts that construct bone matrix

Question 6

Endosteum

Answer 6

Inner surface of bone
