Answer the following questions:

1. Briefly describe the following six general characteristics of synovial joints and their functional significance: articular cartilage, a joint cavity, a joint capsule that surrounds the joint cavity, synovial fluid within the joint cavity, reinforcing ligaments, a rich supply of nerves and blood vessels. Which of the following six characteristics do you think has the least importance in the overall functioning of a synovial joint? Make sure you support your response to the question.

2. Describe the structure of the cranium, formed from the eight cranial bones (2 paired, 4 unpaired). Include any structural features that are specifically associated with a cranial bone (fossa, foramina, canals) as described in the lecture video (meaning you don't have to include all structural features) as well as sutures (parietal bone). What is the functional significance of the presence of these various structural features - fossa, foramina, canals and sutures? Make sure to include specific examples of why a structural feature is important.

3. Describe the structural difference between thick and thin skin in terms of epidermal cell layers. Is the skin of the foot considered thick or thin skin? If an object were to pierce the bottom of your foot, what would be the order of the epidermal cell layers it would pierce? Respond to the statement: When I look at the surface of my skin, I am looking at a layer of dead cells, and I lose millions of these dead cells on a daily basis. If this statement is true, should you worry? Why or why not? Are there cells that have the capability of replacing lost cells?

4. Then generate one short answer question (keep it simple).
