19

Name the main functions of bone

Levers for muscle action, protection of vital organs, support

20

Name all functions of bone

Levers for muscle action, support, protection of organs, mineral depots, site of hematopoesis, storage of fat

21

Describe a long bone

Significantly longer in 1 dimension, found only in limbs, act as levers

Example: Humerus, femur

22

Describe a short bone

Equidimensional, fund only in limbs, used for complex movement

Example: Carpal and tarsal bones

23

Describe flat bones

Reduced in one dimension, site of hematopoesis

Example: Scapula, ribs, some skull bones

24

Describe irregular bones

Irregular bones have jutting processes

Example: vertebrae, pelvis

25

Describe sesamoid bones

Seed shaped, imbedded within tendons, reduce friction between tendon and underlying bone

Example: Patella

26

Describe appendicular skeleton

Bones of the limbs

27

Describe axial skeleton

Bones of the skull, sternum, ribs, vertebral column

28

Describe heterotopic skeleton

Unusual bones, os penis in dog, os cordis in ox. Os rostral in pig

29

Describe compact bone

Dense, cortical bone

30

Describe spongy bone

Made from trabecular or cancellous bone, lies within the 2 compact layers of flat bones

Found in extremities of long bones and forms internal substance of short and irregular bones.
