The Reproductive System Quizlet Questions
Question 1 of 5
Spermatogenesis is a function of the _____.
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.
Question 2 of 5
The outside layer of the oocyte is the _____.
Correct Answer: C
Rationale: The correct answer is C: zona pellucida. The zona pellucida is the glycoprotein layer surrounding the oocyte. It plays a crucial role in fertilization by binding sperm and facilitating the acrosome reaction. The theca interna and externa are layers surrounding the ovarian follicle, not the oocyte itself. The antrum is a fluid-filled cavity within the follicle, not the outer layer of the oocyte. Therefore, the correct choice is C as it directly relates to the outer layer of the oocyte.
Question 3 of 5
The female Bartholin glands correspond to the male _____.
Correct Answer: B
Rationale: The female Bartholin glands are homologous to the male Cowper's glands. Both glands secrete fluid to lubricate the reproductive tract during sexual arousal. The prostate gland (choice A) is not the correct answer as it is a different structure that produces seminal fluid. The seminal vesicles (choice C) secrete a significant portion of the seminal fluid but are not the male counterpart to the Bartholin glands. The glans (choice D) refers to the tip of the penis and is not the correct counterpart to the Bartholin glands. Therefore, the correct answer is B, Cowper's glands.
Question 4 of 5
The shedding and bleeding of the decidua during menses is directly caused by low levels of _____.
Correct Answer: C
Rationale: The shedding and bleeding of the decidua during menses is directly caused by low levels of sex steroids. Sex steroids, specifically estrogen and progesterone, play a crucial role in maintaining the uterine lining. When levels of these hormones drop, it triggers the shedding of the decidua, leading to menstrual bleeding. FSH and LH are pituitary hormones that regulate the menstrual cycle but do not directly cause the shedding of the decidua. GnRH is a hypothalamic hormone that stimulates the release of FSH and LH.
Question 5 of 5
Umbilical cord contains _________
Correct Answer: B
Rationale: The correct answer is B: Cord blood stem cells. Umbilical cord blood contains stem cells that are collected from the blood in the umbilical cord and placenta after a baby is born. These stem cells are known as cord blood stem cells, which are multipotent and have the potential to develop into various types of cells in the body. Pluripotent stem cells (choice A) refer to stem cells that can differentiate into almost any cell type, which is not specifically present in the umbilical cord. Blood stem cells (choice C) are found in bone marrow and are responsible for producing blood cells, but they are not the primary type of stem cells found in umbilical cord blood. Choice D is incorrect because umbilical cord blood indeed contains cord blood stem cells.
