Actions:
 Look
in your text books
starting on page 157 and write
a brief explanation of the
following actions:
 Flexion, Extension, Rotation,
Abduction, Adduction.
Hormones:
PTH
Sex
Hormones
Calcitonin
Human Growth Hormone
PTH
 Released
by:
 Parathyroid
 Response:
 Bones
release
calcium into the
blood stream.
Calcitonin
 Released
by:
 Thyroid
 Response:
 Inhibits
osteoclast
activity
HGH

Released by:
 Pituitary Gland

Response:
 Increases Calcium
retention in bones
and mineralization
Sex Hormones
Estrogen and Testosterone:
 Secreted by:


Testes, Ovaries
Response:
 Increase bone density and maturation.
