Explanation:

1. The shoulder is a type of ball-and-socket joint

The shoulder joint its formed by the humeral head (the ball) and the glenoid fossa (the socket).

2. Which of the following sections of the spinal columns have five vertebrae?

The lumbar section, composed by L1 to L5.

3. The bones of the extremities are part of the  Appendicular Skeleton

"Appendicular" means that it is attached to an axial plane. In the human body de appendix are the limbs and the axial plane is the trunk.

4. The process of moving a body part around a central axis  is called rotation.

An example of this would be your head rotating on top of your shoulders.

5. What is the name of the addition of new layers of the bone?

Apossitional Growth. This is usually happens during childhood and happens to reinforce bone as part of the growth process.

6. What provides bones with flexibility and tensile strength?

Collagen fibers, most importantly Collagen Type I, is the responsible of most of the tensile strength of our body.

7. Bones absorb vitamin  D.

Vitamin D it is used as a "hormone" to induce calcium release from the bone to the blood and helps maintain serum calcium levels.

8. The skull and spinal column are parts of the  Axial Skeleton

9. What type of bone is a skull bone?

A flat bone. Other examples of flat bones are the sternum and the ribs.

10. Appositional growth ends in  adolescence.
