Correct Answer: D
Rationale: When the orthopedic surgeon informs you of a break in the middle region of the humerus, they are referring to the shaft or long portion of the bone, which is known as the diaphysis.

Correct Answer: B
Rationale: The stratum corneum, the outermost layer of the epidermis, is composed of dead skin cells. Areas that are subjected to constant pressure or friction, such as the heel of the foot, tend to have a thicker stratum corneum as a protective mechanism against wear and tear. Therefore, an especially thick stratum corneum would be expected on the heel of the foot, making it the correct answer.

Which type of cholesterol is considered the best for health?
- A. LDL
- B. HDL
- C. VLDL

Correct Answer: B
Rationale: High-density lipoprotein (HDL) is considered the best type of cholesterol for health. HDL helps remove excess cholesterol from the bloodstream, reducing the risk of heart disease. Conversely, low-density lipoprotein (LDL) is often referred to as 'bad' cholesterol as it can lead to plaque buildup in arteries. Very low-density lipoprotein (VLDL) and very high-density lipoprotein (VHDL) are not commonly used terms in cholesterol classification.
