Document Summary
Composed of organic agents collagen, and inorganic agents calcium salts. Provide a framework that supports the body. Protective covering for certain organs and regions of the body. Certain bones contain red bone marrow which produces new red blood cells. Provides sites for muscle attachment, which allows us to use our muscles to move. Bone acts as a storage medium and buffer for calcium in the blood. Blood can change the ph very rapidly, and bones make sure we normalize the ph in the blood. Calcium plays a big role in the bone as a buffer and maintaining its strength. Contain foramina for passage of nerves and vessels. Bones are very thin as the thinness reduces the weight. Bones are also curved to maximize the amount of force it can withstand. Synarthrodial joints: immovable joints found in the cranium. True foramen: a hole that is completely surrounded by bone.
