Regarding respiratory system of fetus
- A. Respiratory bud starts to appear at the ventral wall of foregut at approximately week 10 of gestation
- B. There are 4 stages of development of respiratory system
- C. Development of respiratory tract is not complete until the last week of fetal development.
- D. Epithelial respiratory is derived from endodermal
Correct Answer: A
Rationale: The correct answer is A because the respiratory bud does indeed start to appear at the ventral wall of the foregut around week 10 of gestation. This marks the beginning of respiratory system development. Choice B is incorrect as there are actually 5 stages of respiratory system development. Choice C is also incorrect as the development of the respiratory tract is not fully complete until after birth, not just in the last week of fetal development. Choice D is incorrect because the epithelial respiratory lining is derived from endoderm, not endodermal.

Which structure is the site of sperm production?
- A. Vas deferens
- B. Seminiferous tubules
- C. Albuginea
- D. Epididymis
Correct Answer: B
Rationale: The correct answer is B: Seminiferous tubules. These tubules are located within the testes and are the specific structures where sperm production occurs through a process called spermatogenesis. Sperm cells are produced within the seminiferous tubules and then mature as they move through the epididymis (choice D) and vas deferens (choice A). The albuginea (choice C) is the tough outer covering of the testes and does not play a direct role in sperm production. Therefore, the seminiferous tubules are the primary site for sperm production in the male reproductive system.

Sella turcica is a __________ in the sphenoid bone in which
- B. Groove
- C. Projection
- D. Depression
Correct Answer: D
Rationale: The correct answer is D: Depression. Sella turcica is a saddle-shaped depression in the sphenoid bone that houses the pituitary gland. It is not a groove (B) as it is a deeper concavity. It is not a projection (C) as it is a recessed area rather than a raised structure. It is not a foramen (A) as it is a hollowed-out area rather than a small opening. Therefore, the most accurate description of sella turcica is a depression in the sphenoid bone.
