Explanation / Answer

Answer

25). e. Cervical

The order of vertebrae from top to bottom is as follows.

Cervical--Thoracic--Lumbar--Sacral--Coccyx

26). e. Clavicle

27). a. Humerus

28). d. Ulna

29). b. Femur

30). c. Tibia

31). a. True

Explanation.

Osteoporosis, the most common bone disease, typically does not manifest until late in life, when bone loss begins due to bone breakdown and decreased levels of bone formation. Loss of bone mass leads to the development of structural abnormalities that make the skeleton more fragile.

32). a. Red

Explanation.

Skeletal muscle is further divided into several subtypes:

Type I, slow oxidative, slow twitch, or "red" muscle is dense with capillaries and is rich in mitochondria and myoglobin, giving the muscle tissue its characteristic red color. It can carry more oxygen and sustain aerobic activity.

33). a. True

Explanation.

Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. It is one of nine types of muscular dystrophy.

34). b. Excess bed rest

Explanation.

Most of the time muscle atrophy is simply the result of disuse. While you would think that the leading cause of disuse atrophy is amongst people who are bedridden and unable to move about in order to exercise the muscles, the real culprit for the majority of muscle atrophy cases is a sedentary lifestyle. The good news is that with vigorous exercise this type of atrophy can be reversed. The bad news is, many of us are unwilling to change our way of life in order to get the exercise we need.

35). c. Excess lactic acid
