Semen leaves the male body when the penis is erect and
- A. urination occurs
- B. evacuation occurs
- C. excitement occurs
- D. ejaculation occurs
Correct Answer: D
Rationale: The correct answer is D: ejaculation occurs. When the penis is erect, semen is released from the male body through ejaculation. During sexual arousal, the muscles contract, pushing semen through the urethra and out of the body. Urination (choice A) is a separate process controlled by the bladder, not related to semen release. Evacuation (choice B) refers to bowel movements, not semen release. Excitement (choice C) is a psychological state and does not directly lead to semen leaving the body. Therefore, the correct answer is D as it accurately describes the physiological process of semen leaving the male body during ejaculation.

The cortical area of the ovary contains:
- A. primordial follicles;
- B. mature follicles;
- C. secondary follicles;
- D. blood vessels;
Correct Answer: A
Rationale: Step 1: The cortical area of the ovary is the outer layer where follicles develop.
Step 2: Primordial follicles are the earliest stage of follicle development, found in the cortex.
Step 3: Mature follicles are developed follicles located deeper in the ovary, not in the cortex.
Step 4: Secondary follicles are also more developed than primordial follicles, located deeper.
Step 5: Blood vessels are important for supplying nutrients but are not specific to the cortical area.
Therefore, the correct answer is A as primordial follicles are located in the cortical area, while other choices are found in different regions of the ovary.
Where does fertilization usually occur in the female reproductive system?
- A. Ovary
- B. Vesicular (Graafian) follicle
- C. Uterine (fallopian) tubes
- D. Uterus
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.
Which of the following is a steroid?
- A. FSH
- B. LH
- C. estrogen
- D. GnRH
Correct Answer: C
Rationale: The correct answer is C: estrogen. Estrogen is a type of steroid hormone derived from cholesterol. Steroids are a specific group of lipids characterized by a particular molecular structure. Estrogen plays a vital role in the development and regulation of the female reproductive system.
Choice A, FSH, and choice B, LH, are both peptide hormones, not steroids. Peptide hormones are made up of amino acids and are not derived from cholesterol.
Choice D, GnRH, is also a peptide hormone that regulates the release of other hormones in the body, particularly in the reproductive system.
In summary, estrogen is the only steroid hormone among the options provided, making it the correct choice.
Lower jaw bone is called as
- A. Maxilla
- B. Mandible
- C. Temporal bone
- D. Menton
Correct Answer: B
Rationale: The lower jaw bone is known as the mandible. The mandible is the only movable bone in the skull, forming the lower jaw and holding the lower teeth in place. The maxilla (A) is the upper jaw bone. The temporal bone (C) is a bone that forms part of the skull, but it is not the lower jaw bone. Menton (D) is a landmark on the mandible, not the name of the bone itself. Therefore, the correct answer is B (Mandible) as it is specifically designated as the lower jaw bone.
A nurse goes to a high school to teach students about reducing the risk of sexually transmitted infections. Which of the following is the best answer for providing information on the prevention of STIs?
- A. Have monogamous sex with an infected partner.
- B. Abstain from sexual activities.
- C. Wash any areas where there has been indirect contact with semen or vaginal mucus.
- D. Avoid protected sex until you and sexual partners have completed treatment.
Correct Answer: B
Rationale: Abstinence is the most effective way to prevent STIs.
