1.
*Intramembranous bone formation (within the tissue):: Bone is formed by the osteoblasts which get surrounded by a double layered periosteum. Outer layer is made up of collagen, inner layer is made up of osteoblasts which form bone. *[This occurs in the bones of the skull]

11.
Compact bone is the hard material the makes up the: shaft of long bones and the outside surfaces of other bones.
12.
Diaphysis: the center section of long bones and vertebrae.
13.
Endochondral bone formation occurs in the: long bones and vertebrae.
14.
Endochondral bone formation:: Cartilage is formed first from chondroblasts. It is then invaded by bone cells which replace the cartilage. This occurs in the end sections called the epiphyses and a center section, the diaphysis. This occurs in the long bones and the vertebrae.
15.
Epiphyses: the end sections of long bones and vertebrae.
16.
Formation of bone:: 1. Intramembranous bone formation (within the tissue)
2. Endochondral bone formation
17.
Functions of the bones of the skull: Surround and protect the brain, and participate in the growth of the jaws.
18.
Intramembranous bone formation occurs in the: bones of the skull.
19.
It is covered on the outside with a double layer of: periosteum which is fibrous.
20.
Lower jaw is formed from the: mandible.
21.
Main cells of the bone are: osteoblasts, osteoclasts, and osteocytes.
22.
Middle cranial fossa (much wider than the anterior cranial fossa) contains the: two temporal lobes of the brain.
23.
Nasal bones form the: bridge of the nose
24.
Neurocranium:: region of the skull that surrounds and encases the brain and sensory organs.
25.

The blood vessels of the Haversian system are connected with blood vessels running: perpendicular through tubes called Volkmann's canals.
37.
The center of the bone: the marrow cavity which is a site for blood cell production.
38.
