Reproductive System Quizlet Anatomy Questions
Question 1 of 5
Which structure is formed by the union of the duct from the seminal vesicle and the ampulla of the vas deferens?
Correct Answer: D
Rationale: The correct answer is D: Ejaculatory duct. This structure is formed by the union of the duct from the seminal vesicle and the ampulla of the vas deferens. The ejaculatory duct plays a crucial role in male reproductive anatomy by transporting sperm and seminal fluid to the urethra for ejaculation. The other choices (A: Urethra, B: Spermatic cord, C: Inguinal canal) are incorrect because they do not involve the specific union of the duct from the seminal vesicle and the ampulla of the vas deferens, which is unique to the ejaculatory duct. The urethra is the final pathway for semen release, the spermatic cord contains blood vessels and nerves that supply the testicles, and the inguinal canal is a passage for structures like blood vessels and nerves to pass through the abdominal wall.
Question 2 of 5
Which hormone inhibits the release of FSH from the pituitary gland?
Correct Answer: A
Rationale: Rationale: 1. Inhibin is produced by the ovaries and testes in response to FSH stimulation. 2. Inhibin acts as a negative feedback signal to inhibit further FSH release. 3. This mechanism helps regulate the levels of FSH in the body. Summary: - Relaxin is a hormone involved in pregnancy and does not directly inhibit FSH release. - GnRH stimulates FSH release rather than inhibiting it. - hCG is produced during pregnancy and does not have a direct role in inhibiting FSH secretion.
Question 3 of 5
The general meaning of the term "corpus" is best described by which of the following?
Correct Answer: B
Rationale: The correct answer is B: Body. Corpus commonly refers to a collection of written or spoken texts, which together form a body of work. "Body" is the best choice as it encompasses the idea of a collection or group of related items. A is incorrect as it refers specifically to the abdomen, not the general term. C, Death, and D, Head, are unrelated to the general meaning of "corpus" as they do not convey the idea of a body or collection.
Question 4 of 5
Benign tumors originating in the myometrium are
Correct Answer: D
Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
Question 5 of 5
Sterilization in the male is accomplished by excising a small portion of the:
Correct Answer: A
Rationale: The correct answer is A: Vas deferens. Sterilization in males is typically done through a procedure called a vasectomy, where a small portion of the vas deferens is excised to prevent the transportation of sperm from the testicles to the urethra. The vas deferens is the duct that carries sperm from the epididymis to the ejaculatory duct. Excising a portion of the ejaculatory duct, epididymis, or seminal vesicles would not prevent the transportation of sperm, making choices B, C, and D incorrect.
