Question 1 of 5
Where does fertilization normally take place?
Correct Answer: D
Rationale: The correct answer is D: Ampulla of the fallopian tubes. Fertilization typically occurs in the ampulla of the fallopian tubes, where the sperm meets the egg. The ampulla is the widest part of the fallopian tube, providing the necessary space for fertilization to occur. Sperm must travel through the cervix and uterus to reach the fallopian tubes where fertilization takes place. The ovary is where the egg is released during ovulation but fertilization occurs in the fallopian tubes.
Question 2 of 5
A mature ovarian follicle that is ready to be ejected from an ovary is called a(n) ________.
Correct Answer: B
Rationale: The correct answer is B: vesicular (Graafian) follicle. A mature ovarian follicle ready for ovulation is called a vesicular follicle. It is the final stage before ovulation. A: primary oocyte is incorrect as it refers to an immature egg cell. C: ovum is incorrect as it refers to a mature egg cell after fertilization. D: corpus luteum is incorrect as it forms after ovulation and is responsible for producing progesterone, not the mature follicle.
Question 3 of 5
What is the function of the milky-colored fluids secreted from the prostate?
Correct Answer: C
Rationale: The milky-colored fluid secreted from the prostate cleanses the urethra. This fluid helps neutralize the acidity of the urethra, providing a more suitable environment for sperm to survive. It does not enable sperm to swim or activate them, as these functions are performed by other components of semen. Additionally, it does not neutralize urine, as its primary function is to support sperm survival and motility.
Question 4 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 5 of 5
The egg is fertilized in which anatomical structure?
Correct Answer: B
Rationale: The correct answer is B: Uterus. After fertilization, the egg travels through the fallopian tube and implants in the uterus for further development. The vagina is the birth canal, not the site of fertilization. The fallopian tube is where fertilization typically occurs, but the actual implantation of the fertilized egg occurs in the uterus. The cervix is the lower part of the uterus that connects to the vagina and plays a role in pregnancy but is not where fertilization occurs.
