1. What are the four main regions of the stomach?

• A. Pylorus, cecum, fundus, body
• B. Cardia, fundus, body, pylorus
• C. Duodenum, jejunum, ileum, cecum
• D. Cardia, fundus, body, ileum

Correct answer: B

Rationale: The correct answer is B: Cardia, fundus, body, pylorus. The four main regions of the stomach are the cardia (where food enters), fundus (upper part), body (largest part), and pylorus (exit part to the small intestine). These regions play specific roles in the digestion process. Choice A is incorrect because the cecum is part of the large intestine, not the stomach. Choice C lists parts of the small intestine, not the stomach. Choice D is incorrect as the ileum is the last part of the small intestine, not a region of the stomach.

2. What is the anatomical term for the back of the body? Example: Shoulder blade.

• A. Anterior
• B. Superior
• C. Posterior
• D. Inferior

Correct answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

3. What is the medical term for an ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

4. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).

5. Muscle soreness after exercise is often caused by microscopic tears in muscle fibers. This is called

• A. Atrophy
• B. Hypertrophy
• C. DOMS (Delayed Onset Muscle Soreness)
• D. Spasm

Correct answer: C

Rationale: Muscle soreness after exercise is often caused by microscopic tears in muscle fibers, leading to Delayed Onset Muscle Soreness (DOMS). Atrophy refers to the wasting away of muscle tissue, hypertrophy is the increase in muscle size, and spasm is an involuntary contraction of a muscle. DOMS typically occurs 24 to 72 hours after intense exercise and is characterized by muscle stiffness, tenderness, and reduced range of motion. It is a normal response to unfamiliar or strenuous physical activity and indicates that the muscles are adapting to the workload. Therefore, the correct answer is C (DOMS) as it specifically describes the phenomenon of muscle soreness resulting from microscopic tears in muscle fibers, distinguishing it from the other choices which refer to different physiological processes or conditions.
