Reproductive System Quizlet Anatomy Questions
Question 1 of 5
Where does implantation of the blastocyst occur?
Correct Answer: B
Rationale: The correct answer is B: endometrium. After fertilization, the blastocyst travels through the uterine tubes and implants into the endometrium for further development. The endometrium is the inner lining of the uterus where implantation occurs to establish pregnancy. The uterine tubes (choice A) are the site of fertilization, but not implantation. The cervix (choice C) is the lower part of the uterus that connects to the vagina and does not play a role in implantation. The ovary (choice D) is where the egg is released during ovulation and not the site of implantation.
Question 2 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 3 of 5
The uterine phase where the thickness of the endometrium doubles is the
Correct Answer: C
Rationale: The correct answer is C: Proliferative phase. During this phase, estrogen levels increase, stimulating the endometrium to thicken and proliferate. This prepares the uterus for potential implantation of a fertilized egg. The other choices are incorrect because: A: Menstrual phase is when the endometrium sheds, not thickens. B: Preovulatory phase is characterized by the maturation of the ovarian follicles, not endometrial thickening. D: Follicular phase is synonymous with the preovulatory phase and focuses on ovarian follicle development, not endometrial thickening.
Question 4 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 5 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.
