Document Summary
Sinus: the vertebral column includes seven cervical vertebrae, twelve thoracic vertebrae, one sacrum of five fused vertebrae and one coccyx formed from three to five fused vertebrae, the first cervical vertebra is also known as the atlas. Compact bone has osteons that look like onion-like rings closely packed together. Compact bone provides strength and support in the shaft and bone surface regions. Spongy bone reduces the weight of the bone and provides spaces for red bone marrow. An example of this joint is the attachment of a tooth to its socket. The term refers to its similarity to a nail hammered into wood. This joint is held firmly in place by a fibrous periodontal ligament. A joint whose fibers are longer and the attached bones are more movable. A joint where two bones are bound by longer collagenous fibers. Joint that binds the distal ends of the tibia and fibula together.
