Q

Role of calcium phosphate in bone

A

Confers great compressive strength

17
Q

Role of collagen in bone

A

Confers great tensile strength

18
Q

Role of osteoblasts

A
  • synthesis and deposit osteoid

- then deposit calcium phosphate into the osteoid

19
Q

Role of osteoclasts

A
  • break down bone and uptake minerals in resorption
20
Q

Nutrient artery

A

Supplies the bone marrow

Enters near the middle of the diaphysis

21
Q

Examples of where you can find short bones

A

Carpal bones in the wrist

Tarsal bones in the ankles

22
Q

Examples of where you can find long bone

A

Femur

Humerus

23
Q

Examples of where you can find irregular bone

A

Vertebrae

24
Q

Examples of where you can find sesamoid bones

A 
Embedded in tendons 
The patella (knee cap)
25
Q

Plane joint

A
  • two flat surfaces sliding against each other
