Compact bone is made up of _______________ cemented together
Compact bone consists of closely packed osteons
- White blood cells, especially lymphocytes, the cells that attack bacteria in the blood.
- Fluid from the intestines called chyle, which contains proteins and fats.
which bones are part of the cranium?
- Frontal bone. This is the flat bone that makes up your forehead. It also forms the upper portion of your eye sockets.
- Parietal bones. This a pair of flat bones located on either side of your head, behind the frontal bone.
- Temporal bones. This is a pair of irregular bones located under each of the parietal bones.
- Occipital bone. This is a flat bone located in the very back of your skull. It has an opening that allows your spinal cord to connect to your brain.
- Sphenoid bone. This is an irregular bone that sits below the frontal bone. It spans the width of your skull and forms a large part of the base of your skull.
- Ethmoid bone. This is an irregular bone located in front of the sphenoid bone. It makes up part of your nasal cavity.
