1. Which of the following organs functions as both an endocrine and exocrine gland?

• A. The kidney
• B. The spleen
• C. The pancreas
• D. The stomach

Correct answer: C

Rationale: The pancreas is the correct answer as it functions as both an endocrine and exocrine gland. The endocrine function involves secreting insulin and glucagon into the bloodstream to regulate blood sugar levels, while the exocrine function involves releasing digestive enzymes into the small intestine to aid in digestion. The kidney (Choice A) primarily functions in the excretory system by filtering blood and producing urine. The spleen (Choice B) is involved in the immune system and blood storage but does not have endocrine or exocrine functions. The stomach (Choice D) is mainly an organ of the digestive system, secreting gastric juices to aid in digestion, but it does not have a dual endocrine and exocrine function like the pancreas.

2. Using anatomical terms, what is the relationship of the sternum to the deltoid?

• A. Medial
• B. Lateral
• C. Superficial
• D. Posterior

Correct answer: A

Rationale: The sternum is located at the midline of the body, closer to the center, making it medial to the deltoid. The deltoid muscle is positioned on the lateral side of the upper arm, away from the midline. Therefore, the correct relationship of the sternum to the deltoid is medial. 'Lateral' is incorrect as it refers to a position farther away from the midline, 'Superficial' is incorrect as it relates to a structure being closer to the surface, and 'Posterior' is incorrect as it indicates a position behind or toward the back.

3. What is the name of the wart-like growths caused by the human papillomavirus (HPV)?

• A. Keloids
• B. Keloids
• C. Papillomas
• D. Carcinomas

Correct answer: C

Rationale: The correct answer is 'Papillomas.' Papillomas are benign wart-like growths caused by the human papillomavirus (HPV). Keloids are raised scars that occur at the site of an injury due to excessive collagen formation, while carcinomas are malignant tumors arising from epithelial cells. When identifying the growths specifically related to HPV, papillomas are the most appropriate term.

4. Which of the following hormones would cause skin color to become darker?

• A. Follicle-stimulating
• B. Growth-stimulating
• C. Thyroid-stimulating
• D. Melanocyte-stimulating

Correct answer: D

Rationale: The correct answer is D, Melanocyte-stimulating. Melanocyte-stimulating hormone (MSH) stimulates melanocytes in the skin to produce more melanin, leading to darker skin pigmentation. Choices A, B, and C are incorrect as Follicle-stimulating hormone (FSH) stimulates follicle growth in the reproductive system, Growth-stimulating hormone is a vague term not specific to any known hormone, and Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, not affecting skin color pigmentation.

5. Which organ is responsible for filtering blood and removing waste products?

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is the kidneys. The kidneys filter blood and remove waste products through the formation of urine. The liver primarily functions in detoxification and metabolism. The spleen is involved in blood filtering and immune function. The pancreas produces digestive enzymes and insulin, not involved in filtering blood.
