-
Long
- Cylindrical shaft with knobby ends
- longer than it is wide
- mostly compact bone with some spongy
- slightly curved for strength
-
Short
- small, chunky, solid bones
- as wide as the are long
- mostly spongy
-
Flat
- broad, flat shape
- thin bones
- two plates of compact bone with spongy between
-
irregular
- Chunky, complex shapes
- varying amounts of compact and spongy bone
-
Sutural, Wormian
Small, irregular bones found along cranial sutures, esp. related to the parietal bone.
-
Sesamoid
- formed after birth in tendones where the tendon passes over a joint
- act to decrease friction on the tendon and may change muscular pull direction
