Sperm production begins in the
- A. seminiferous tubules
- B. epididymis
- C. vas deferens
- D. ejaculatory duct
Correct Answer: A
Rationale: The correct answer is A: seminiferous tubules. Sperm production starts in the seminiferous tubules of the testes through a process called spermatogenesis, involving the division and maturation of germ cells. The other choices, B: epididymis, C: vas deferens, and D: ejaculatory duct, are incorrect as they are not sites of sperm production but rather play roles in sperm storage, transport, and ejaculation, respectively. The seminiferous tubules are specifically designed for sperm production, making them the correct choice in this context.

Spermatogenesis is a function of the _____.
- A. tunica albuginea
- B. rete testis
- C. seminiferous tubule
- D. seminal vesicle
Correct Answer: C
Rationale: The correct answer is C: seminiferous tubule. Spermatogenesis is the process of sperm production and occurs within the seminiferous tubules of the testes. These tubules contain specialized cells called germ cells that undergo meiosis to produce sperm. The tunica albuginea is a fibrous layer surrounding the testes, the rete testis is a network of tubules where sperm is transported, and the seminal vesicle is a gland that produces seminal fluid, not involved in sperm production. Therefore, the seminiferous tubule is the correct choice for spermatogenesis.
The ovarian follicles are located in the following structures, EXCEPT:
- A. the Fallopian tubes;
- B. the uterus;
- C. the medullar area of the ovary;
- D. the cortical area of the ovary;
Correct Answer: B
Rationale: The correct answer is B, the uterus. Ovarian follicles are structures within the ovaries where oocytes (eggs) develop. The Fallopian tubes, medullar area, and cortical area of the ovary all contain ovarian follicles. The uterus, on the other hand, is not where ovarian follicles are located; it is the organ where a fertilized egg implants and a pregnancy develops. Therefore, the correct answer is B because the uterus is not a structure where ovarian follicles are present.
The radius, ulna and humerus forms the ___________ joint.
- A. Knee
- B. Elbow
- C. Ankle
- D. Shoulder
Correct Answer: B
Rationale: The correct answer is B: Elbow. The radius, ulna, and humerus form the elbow joint. The ulna and humerus articulate at the trochlear notch, forming the hinge joint, while the radius articulates with the humerus at the capitulum, allowing for rotation. This combination of movements allows for flexion and extension of the forearm. The other choices, knee (A), ankle (C), and shoulder (D), involve different bones and joints in the body that do not include the radius, ulna, and humerus.
