The Human Reproductive System Questions
Question 1 of 5
For fertilization to be accomplished, of the secondary sex characteristics sperm release enzymes to break seen in young women? down the corona radiata from their
Correct Answer: D
Rationale: The correct answer is D: acrosomes. Acrosomes are specialized vesicles in the head of the sperm that contain enzymes to help the sperm penetrate the outer layer of the egg during fertilization. Enlargement of the accessory organs (choice A), mitochondria (choice B), and breast development (choice C) are not directly related to the process of fertilization and do not involve the release of enzymes to break down the corona radiata. Acrosomes play a crucial role in the fertilization process by facilitating the penetration of the egg's protective layers, making choice D the correct answer.
Question 2 of 5
With respect to Sertoli cells which of the following statements is incorrect
Correct Answer: D
Rationale: The correct answer is D because Sertoli cells do secrete inhibin, but it does not inhibit luteinizing hormone secretion. Inhibin actually inhibits follicle-stimulating hormone (FSH) secretion. Sertoli cells support spermatogenesis by nourishing developing sperm (A), they are stimulated by testosterone (B), and they also phagocytose defective sperm (C). Therefore, option D is incorrect as it misrepresents the role of inhibin in the endocrine regulation of the male reproductive system.
Question 3 of 5
The tiny female sex cell that unites with male sperm to form a zygote or fertilized egg.
Correct Answer: B
Rationale: The correct answer is B: Ovum. The ovum is the mature female sex cell that unites with a male sperm during fertilization to form a zygote. Ovary (A) is the organ that produces eggs but is not the actual female sex cell. Gonad (C) is a general term for reproductive organs, not the specific female sex cell. Gametes (D) refer to both male and female sex cells, so it is a broad term and not the specific female sex cell. The ovum is the only choice that accurately represents the tiny female sex cell involved in fertilization.
Question 4 of 5
The two oval-shaped organs that produce, store, and release human eggs are called __________________.
Correct Answer: B
Rationale: The correct answer is B: ovaries. Ovaries are the organs responsible for producing, storing, and releasing human eggs. They are oval-shaped and play a crucial role in the female reproductive system. The other choices are incorrect because: A: clitoris is a small, sensitive organ located near the entrance of the vagina, not involved in egg production. C: Fallopian tubes are responsible for transporting eggs from the ovaries to the uterus, not for producing or storing eggs. D: Vagina is the muscular tube connecting the uterus to the outside of the body, not involved in egg production.
Question 5 of 5
The roles of the testicle are:
Correct Answer: C
Rationale: Rationale for correct answer (C): The main function of the testicles is spermatogenesis, which is the process of producing sperm cells. This is a crucial role in male reproductive system. Spermatogenesis occurs in the seminiferous tubules of the testes. Other functions like producing androgenic hormones (choice B) are mainly carried out by the Leydig cells in the testes, not the testicles themselves. While the testicles do play a role in semen production (choice D), this is not their primary function. Therefore, the correct answer is C as it directly relates to the main purpose of the testicles in the male reproductive system.
