The fructose in semen is secreted by

Correct Answer: C

Rationale: The correct answer is C, the seminal vesicles. Seminal vesicles secrete fructose in semen to provide energy for sperm motility. This process occurs after sperm leave the epididymis and seminiferous tubules, ruling out choices A and B. The prostate glands contribute to the alkaline fluid in semen, not fructose, eliminating choice D. Therefore, choice C is correct due to its role in providing energy for sperm function.

Correct Answer: B

Rationale: Correct Answer: B - Nipple is lubricated by sebaceous gland Rationale: 1. Sebaceous glands produce sebum, which lubricates the skin. 2. The nipple is a part of the skin, and sebaceous glands present in the areola secrete sebum to lubricate the nipple. 3. This lubrication helps protect the nipple during breastfeeding. Summary of other choices: A: Lactiferous duct is mainly lined by simple cuboidal epithelium - Incorrect. The lactiferous duct is lined by stratified cuboidal and columnar epithelium. C: Terminal ductules are seen in lactating mammary gland - Incorrect. Terminal ductules are present in non-lactating mammary glands. D: Interlobular stroma increase in pregnancy - Incorrect. Interlobular stroma does not significantly increase in pregnancy; rather, the alveoli and ducts enlarge during this period.

Correct Answer: A

Rationale: The correct answer is A: Assist the client in sitting up after the procedure. This is important to prevent complications like vasovagal response or fainting due to sudden positional changes. Sitting up slowly helps stabilize blood pressure and prevent dizziness. B: Providing a pad for dye stains is not the most important action as it is a minor concern compared to client safety post-procedure. C: Taking antibiotics has no direct relevance to the hysterosalpingogram procedure, so it is not the most important action. D: Informing the client about potential shoulder pain is helpful, but ensuring immediate safety by assisting the client in sitting up takes precedence.

Correct Answer: C

Rationale: The correct answer is C: acrosome. Lysosomal-like enzymes are found in the acrosome of sperm cells, where they help in breaking down the outer layers of the egg during fertilization. Sertoli cells (A) provide nourishment and support for developing sperm cells. The sperm head (B) contains genetic material but not lysosomal-like enzymes. The sperm tail (D) is responsible for movement and does not contain lysosomal-like enzymes. Therefore, the acrosome (C) is the structure that specifically houses these enzymes for the fertilization process.

Correct Answer: C

Rationale: Step 1: ICSH stands for interstitial cell-stimulating hormone. Step 2: Interstitial cells are found in the testes and produce testosterone. Step 3: ICSH targets these interstitial cells to stimulate testosterone production. Step 4: Therefore, the correct answer is C: interstitial cells. Summary: A, B, and D are incorrect as ICSH does not target the prostate, seminiferous tubule, or seminal vesicle.
