Anatomy Reproductive System Quizlet Questions
Question 1 of 5
Which gland surrounds the upper portion of the urethra just below the junction with the urinary bladder?
Correct Answer: D
Rationale: The correct answer is D: Prostate. The prostate gland surrounds the upper portion of the urethra just below the junction with the urinary bladder. It secretes a fluid that makes up a significant portion of semen. The other choices are incorrect because: A: Ejaculatory gland is not a correct anatomical structure. B: Seminal vesicles are located behind the bladder and contribute to semen production. C: Bulbourethral glands are located at the base of the penis and secrete a lubricating fluid during arousal.
Question 2 of 5
Where does fertilization usually occur in the female reproductive system?
Correct Answer: C
Rationale: The correct answer is C, the uterine (fallopian) tubes. This is where fertilization usually occurs as it is the site where the egg and sperm meet. The egg is released from the ovary and travels through the fallopian tube where it can be fertilized by sperm. If fertilization occurs, the resulting embryo will then travel to the uterus for implantation. The other choices are incorrect because fertilization does not typically occur in the ovary (A) or vesicular (Graafian) follicle (B). While the uterus (D) is where the embryo implants and develops into a fetus, fertilization itself does not occur there.
Question 3 of 5
Which hormone is primarily produced by the corpus luteum?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. The corpus luteum is a temporary endocrine structure in the ovaries that forms after ovulation. Its main function is to produce progesterone, which helps prepare the uterine lining for implantation of a fertilized egg. Follicle stimulating hormone (FSH) is produced by the pituitary gland to stimulate follicle development, not by the corpus luteum. Testosterone is mainly produced by the testes in males and a small amount by the ovaries in females, not by the corpus luteum. Progesterone is the key hormone produced by the corpus luteum, making choice C the correct answer.
Question 4 of 5
The ducts or tubes responsible for the ________. receiving the ovulated oocyte and
Correct Answer: D
Rationale: The correct answer is D: uterine (fallopian) tubes. These tubes are responsible for receiving the ovulated oocyte (egg) and providing the site for fertilization. The fallopian tubes are specifically designed to transport the egg from the ovary to the uterus for potential fertilization by sperm. Choice A, glans penis, is incorrect as it is part of the male reproductive system and not involved in receiving the ovulated egg. Choice B, shaft, is also incorrect as it refers to the main part of the penis and is not related to female reproductive functions. Choice C, scrotum, is incorrect as it is part of the male reproductive system and has no role in receiving the ovulated egg.
Question 5 of 5
Each spermatid and each ovum have ________. ________.
Correct Answer: D
Rationale: The correct answer is D: 23 chromosomes. Spermatids and ova are haploid cells formed through meiosis, containing only half the number of chromosomes (23) as a normal diploid cell. This is essential for maintaining the proper chromosome number when fertilization occurs. Glans penis and shaft of the penis (choices A and C) are structures related to the male reproductive system but are not present in spermatids or ova. Having 23 pairs of chromosomes (choice B) would result in a total of 46 chromosomes, which is incorrect for these gametes.
