The ducts or tubes responsible for the ________. receiving the ovulated oocyte and
- A. glans penis providing the site for fertilization are
- B. shaft the ________.
- C. scrotum
- D. uterine (fallopian) tubes
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.

Which gland surrounds the upper portion of the urethra just below the junction with the urinary bladder?
- A. Ejaculatory
- B. Seminal vesicles
- C. Bulbourethral
- D. Prostate
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.
Which of the following STIs are curable?
- A. Chlamydia and gonorrhea
- B. Gonorrhea and herpes
- C. Herpes and venereal warts
- D. AIDS and syphilis
Correct Answer: A
Rationale: Chlamydia and gonorrhea are bacterial infections that can be cured with antibiotics.
Which hormone triggers ovulation?
- A. GnRH
- B. LH
- C. FSH
- D. Estrogen
Correct Answer: B
Rationale: The correct answer is B: LH (Luteinizing Hormone) triggers ovulation. Firstly, LH surge stimulates the release of the mature egg from the ovary. Secondly, it plays a crucial role in the development of the corpus luteum, which produces progesterone to prepare the uterus for potential implantation. GnRH (Choice A) is the hormone that stimulates the release of LH and FSH (Choice C) from the pituitary gland, but it does not directly trigger ovulation. Estrogen (Choice D) is involved in the regulation of the menstrual cycle and prepares the uterine lining for implantation but does not directly trigger ovulation.
Variations in eye color are determined by the number of pigmented cells in the:
- A. Ciliary epithelium
- B. Iris epithelium
- C. Iris stroma
- D. Corneal stroma
Correct Answer: C
Rationale: The correct answer is C: Iris stroma. The iris stroma contains melanocytes, which are responsible for producing the pigmented cells that determine eye color. These pigmented cells give the iris its color by absorbing and reflecting light. The ciliary epithelium (choice A) is not involved in determining eye color. The iris epithelium (choice B) is mainly responsible for controlling the size of the pupil, not for determining eye color. The corneal stroma (choice D) is a layer of the cornea that primarily provides structural support and transparency to the eye, but it does not play a role in determining eye color.
The main function of progesterone in the menstrual cycle is to CHAPTER 4: REPRODUCTION COMPILED BY: ZAIDI YAACOB UNAUTORIED DUPLICATION IS PROBIHITED, FOR THE CIRCULATION OF BIO095 STUDENTS ONLY
- A. stimulate development of corpus luteum .
- B. stimulate development of the follicl
- C. maintain endometrium lining.
- D. trigger ovulation.
Correct Answer: C
Rationale: The correct answer is C because progesterone's main function in the menstrual cycle is to maintain the endometrium lining. Progesterone is produced by the corpus luteum after ovulation, and it helps prepare the endometrium for implantation of a fertilized egg. This hormone ensures that the endometrium is thick and ready to support a potential pregnancy.
Choice A is incorrect because progesterone is not responsible for stimulating the development of the corpus luteum; instead, it is produced by the corpus luteum itself.
Choice B is incorrect because progesterone does not stimulate the development of the follicle. The follicle is primarily influenced by estrogen during the follicular phase of the menstrual cycle.
Choice D is incorrect because ovulation is triggered by a surge in luteinizing hormone (LH), not progesterone. LH surge causes the release of the egg from the follicle.
