Chapter 34 Section 34.2 Skin:The Body's Protection Bones: The Body's Support pg. 904 ?'s 1-5

1. The appendicular skeleton includes the bones of the arms and legs and structures associated with them, such as the shoulder and hip bones, wrists, ankles, fingers, and toes. While the axial skeleton includes only the skull and the bones that support it, such as the vertebral column, the ribs, and the sternum.

2. The four main kinds of joints of movable joints are the joints, which are found where two or more bones meet; example: the skull. Ligament, which is a tough band of connective tissue that attaches one bone to another; example: knee. The bursae, located on the outside of the joints; example: the shoulder. And lastly the Tendons, which are thick bands of connective tissue, attaches muscles to bones; examples: wrist, ankle, and knee.

3. A compact bone is different from the spongy bone because the compact bone is the surrounding of every bone in a layer of hard bone and it also surrounds less dense bone than the spongy bone.

4. The functions of the skeletal system are to provide the framework for the body.

5. It would be impossible for bones to grow from within because, in normal bone formation and bone resorption are closely coupled processes involved in the normal remodeling of the bone.
