1

Axial skeleton

bones of the skull, vertebral column, and rib cage

2

Appendicular skeleton

bones of the upper and lower limbs, shoulder, and hip

3

Long bones

longer than they are wide (e.g., humerus)

4

Short bones

Cube- shaped bones of the wrist and ankle
Bones that form
within tendons (e.g., patella)

5

Flat bones

thin, flattened, and a bit curved (e.g., sternum, and most skull bones)

6

Irregular bones

bones with complicated shapes (e.g., vertebrae and hip bones)

7

Function of Bones

Support
Protection
Movement
Mineral storage (calcium and phosphorus)
Blood cell formation (hematopoiesis occurs within the marrow cavities of bones)

8

Bulges, depressions, and holes that serve as

Sites of attachment for muscles, ligaments,
and tendons
Joint surfaces
Conduits for blood vessels and nerves

Tuberosity

rounded projection

10

Crest

narrow, prominent ridge of bone

11

Trochanter

large, blunt, irregular surface
