Which ligament arises from the pubic symphysis in males?

Correct Answer: C

Rationale: The correct answer is C: Suspensory ligament. This ligament arises from the pubic symphysis in males and supports the male reproductive organs. It helps suspend the penis and testes in the scrotum. The Fundiform ligament (A) supports the penis, the Broad ligament (B) supports the uterus, and the Ejaculatory ligament (D) is not a ligament associated with the pubic symphysis in males.

Correct Answer: C

Rationale: The correct answer is C: Increasing the rate and depth of breathing during sexual arousal. The reproductive system does not directly contribute to the rate and depth of breathing. The main function of the reproductive system is to produce and deliver gametes for reproduction. It does not have a direct role in regulating respiratory functions. Choices A, B, and D are incorrect because the reproductive system does contribute to maintaining bone health, regulating cholesterol levels in males, and stimulating muscle growth in males. These functions are known contributions of the reproductive system to the body systems.

Correct Answer: C

Rationale: The correct answer is C: Fallopian tubes. These tubes are also known as uterine tubes because they connect the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus. The other choices are incorrect because: A: Vas deferens is a tube that carries sperm from the epididymis to the urethra in males. B: Epididymis is a coiled tube located on the back of each testicle where sperm mature. D: Vagina is the muscular tube that connects the cervix to the external genitalia in females.

Correct Answer: C

Rationale: The correct answer is C: Vasovasostomy. This procedure involves reconnecting the vas deferens to reverse a vasectomy, allowing sperm to be present in the ejaculate again. Orchiopexy (A) is the surgical fixation of a testicle in the scrotum and is not related to reversing sterilization. Vasectomy (B) is the sterilization procedure itself, not the reversal. Bilateral orchiectomy (D) is the surgical removal of both testicles and is a permanent sterilization method, not a reversal procedure. Therefore, the correct choice is C as it directly addresses the reversal of male sterilization.

Correct Answer: B

Rationale: The correct answer is B: Flagella. Flagella are whip-like structures that provide motility to sperm cells. They enable the sperm cell to move towards the egg for fertilization. Cilia (choice A) are shorter hair-like structures involved in movement but are not found on sperm cells. Pseudopodia (choice C) are temporary projections used for cell movement in some organisms, not sperm cells. Dendritic processes (choice D) refer to branching extensions of nerve cells, not involved in sperm motility. Therefore, flagella is the most appropriate choice for the hair-like process on the sperm cell that makes it motile.
