18. The structure labeled (A, C) in the diagram above contains a series of Haversian canals through which nerves and blood vessels run. 19. (Compact, Spongy) bone makes up the layer labeled B in the diagram. 20. The membrane labeled C is the (bone marrow, periosteum). 21. A human’s (internal, external) skeleton provides support for the body. 22. Bones store supplies of (calcium and phosphorus, carbon and sulfur) that can be used by other tissues of the body. 23. (Blood Cells, Osteocytes) are produced in the bone marrow. 24. The long bones of the legs have growing points at each end called (fixed joints, growth plates). 25. The place where two bones meet is called a (joint, muscle). 26. The bones of the spinal column are (fixed, slightly movable) joints. 27. The hinge joints found in the elbows and knees are (slightly, freely) movable joints.

The membrane that covers each bone contains nerves. The Haversian canals contain nerves and blood vessels and run through compact bone. When the bone is injured so are these parts. The nerves of both transmit pain to our brains. A C B C E B
