Anatomy Reproductive System Quizlet Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The presence of more oxytocin oxygen to, and remove waste from, receptors in the uterus leads to weak, irregular contractions known as the embryonic blood by the ________ ________. week of pregnancy.
Correct Answer: C
Rationale: The correct answer is C: Braxton Hicks contractions. These contractions are weak, irregular contractions that occur in the uterus during pregnancy. They are often referred to as "practice contractions" as the body prepares for labor. The presence of more oxygen and removal of waste from the uterus can trigger Braxton Hicks contractions. Choice A, dystocia, refers to difficult or prolonged labor, not weak contractions. Choice B, first week, is not relevant to the question as Braxton Hicks contractions typically occur later in pregnancy. Choice D, second week, is also not correct as Braxton Hicks contractions occur later in pregnancy, typically in the third trimester.
Question 5 of 5
During the follicular phase of the female menstrual cycle
Correct Answer: D
Rationale: During the follicular phase, the correct answer is D because it is when the ovaries produce estrogen to stimulate the thickening of the uterine lining. This prepares the uterus for potential implantation of a fertilized egg. In contrast, choice A is incorrect because the corpus luteum is not formed until after ovulation. Choice B is incorrect as the corpus luteum forms after the egg is released. Choice C is incorrect because progesterone is mainly secreted during the luteal phase to maintain the uterine lining.
