Calcitonin (from the thyroid gland) and Ca+ is deposited
Which hormone stimulates the osteoblast in build up of bone. What mineral is deposited into bone after activation by this hormone?
200
amino acids---> peptides ---> polypeptide
What is the most simple form of proteins?
300
Parathhormone- increase Ca+ levels in blood
Calcitonin- lowers Ca+ levels in blood
Growth Hormone- stimulates growth of bone (puberty)
testosterone & estrogen- stimulates growth

300
Deep depression in bone. Give an example.
What is a fosa?
300
Bifid spinus process, odontoid (tooth) process that articulates with the atlas vertebra to allow head rotation.
What is the axis vertebra? Give some of it's major characteristics.

300
Lipids
What are long chains of carbon, hydrogen, and very few oxygen?
400
Spongy- flat bones, contains bone marrow and produces blood cells, originated from connective tissue
compact- long bones, originates from cartilage

thoracic vertebra
what are the vertebra that articulate with ribs?
500
-area fills with blood to clot (hematoma)
-healthy surrounding blood vessels provide osteoblasts
-bony callus forms around fracture
-osteoblasts remove callus to rebuild bone
