4

tuberosity

large, rounded projection, may be roughened

5

crest

11

12

19

fissure

21

Long Bone - 3 points

greater length than width, diaphysis & 2 epiphyses, sightly curved for strength

Short Bone - 3 points

cube shaped, nearly equal in length and width, spongy in texture except at their surface of compact bone

24

Irregular Bone - 2 points

complex in shape, don't fit into the other 3 groups

25
