Human Reproductive System pdf Questions
Question 1 of 5
The inner mucosal layer of the uterus that is sloughed off approximately every 28 days is called the ________.
Correct Answer: A
Rationale: The correct answer is A: endometrium. The endometrium is the inner mucosal layer of the uterus that sheds during menstruation. It is where implantation of a fertilized egg occurs. Myometrium (B) is the middle muscular layer, responsible for uterine contractions. Perimetrium (C) is the outer layer of the uterus. Epimetrium (D) is not a recognized term in anatomy.
Question 2 of 5
Of the two functional areas of the years of age is known as ________. It blastocyst, the three primary germ is during this time that the reproductive layers form from the ________. organs grow to their adult size and
Correct Answer: D
Rationale: The correct answer is D: adulthood. The question is referring to the two functional areas of life - childhood and adulthood. During adulthood, organs grow to their adult size and mature, reproductive organs become functional under the influence of hormones. A: amnion become functional under the influence - Incorrect. Amnion is a membrane surrounding the embryo, not related to the functional areas of age. B: morula of hormones - Incorrect. Morula is an early stage of embryonic development, not related to the functional areas of age. C: inner cell mass - Incorrect. Inner cell mass is a part of the blastocyst, not related to the functional areas of age.
Question 3 of 5
The hormone(s) responsible for hymen. secondary sex characteristics in
Correct Answer: B
Rationale: The correct answer is B: estrogens. Estrogens are the primary hormones responsible for the development of secondary sex characteristics in females, including the formation of the hymen. Estrogens play a crucial role in regulating menstrual cycles, breast development, and overall reproductive health in females. Progesterone (choice D) is primarily involved in regulating the menstrual cycle and supporting pregnancy but is not directly responsible for hymen development. Choices A and C do not provide accurate or relevant information related to the development of secondary sex characteristics or the hymen.
Question 4 of 5
Primary spermatogonium undergo:
Correct Answer: B
Rationale: The correct answer is B. Primary spermatogonium undergo mitosis to replicate and maintain the diploid chromosome number, then meiosis to reduce the chromosome number, resulting in secondary spermatocytes. Choice A is incorrect as it skips meiosis. Choice C is incorrect as it suggests two meiotic divisions from primary spermatogonium, which is not accurate. Choice D is incorrect because it fails to mention the initial step of mitosis before meiosis in the process.
Question 5 of 5
The secondary oocyte completes its second meiotic division
Correct Answer: A
Rationale: The correct answer is A: just after fertilization. After fertilization, the secondary oocyte completes its second meiotic division, forming a mature ovum and a polar body. This process occurs to ensure the correct chromosome number in the resulting zygote. Choices B, C, and D are incorrect because the completion of the second meiotic division occurs specifically after fertilization, not before or just after ovulation or fertilization.
