1
Q

ossification

A

bone formation - gradual replacement of cartilage; continues until fully grown

2
Q

osteoblasts

A

immature osteocytes

3
Q

osteoclasts

A

bone phagocytes; break down bone

- function is to reabsorb or digest

4
Q

parathyroid gland

A
  • secretes hormone for maintaining calcium levels

- hormone allows calcium to leave bone & enter bloodstream

5
Q

thyroid gland

A

secretes hormone that allows calcium to leave the blood and head to bones

6
Q

calcium phosphate

A

substance that gives bone its characteristic hard quality

7
Q

Vitamin D

A

helps calcium pass thru the lining of small intestine & into blood stream

8
Q

epiphysis

A

each end of a long bone (beyond the epiphyseal line/growth plate)

9
Q

bone processes

A

enlarged tissue that normally extends out from bones to serve as attachments to muscles & tendons & ligaments

10
Q

acromion process

A

shoulder; lateral extension of scapula

11
Q

olecranon process

A

end of ulna (elbow)

12
Q

bone depressions

A

openings or hollow regions in a bone
Function: help to join one bone to another; serves as a passageway for blood vessels & nerves
Ex. foramen - opening for blood vessels & nerves
acetabulum - socket of hipbone; where femur sits

13
