Identify the CORRECT strategy to achieve external fertilization.
- A. Female organism will modify its body parts to receive male gametes.
- B. Fertilization must occur at night to avoid predators.
- C. Eggs and sperm must be shed simultaneously into water.
- D. The release of eggs is more frequent than the release of sperm.
Correct Answer: C
Rationale: The correct strategy for external fertilization is to have eggs and sperm shed simultaneously into water. This allows the gametes to meet and fertilize outside of the organism's body. This method is effective in aquatic environments where the chances of gametes coming into contact are increased. Choice A is incorrect as it describes internal fertilization. Choice B is irrelevant to the process of external fertilization. Choice D is incorrect as the frequency of egg and sperm release does not determine the success of external fertilization.

This is an inflammation of the fallopian tubes and the pelvic organs secondary to infections with gonococcus or chlamydia
- A. Ovarian cyst
- B. Endometriosi
- C. PID
- D. Cervicitis
Correct Answer: C
Rationale: Step 1: Pelvic inflammatory disease (PID) is an infection of the fallopian tubes and pelvic organs.
Step 2: PID is commonly caused by gonococcus or chlamydia infections.
Step 3: Ovarian cyst (A) is a fluid-filled sac on the ovary, not related to infections.
Step 4: Endometriosis (B) is the growth of endometrial tissue outside the uterus, not typically associated with infections.
Step 5: Cervicitis (D) is an inflammation of the cervix, not involving the fallopian tubes and pelvic organs.
About the external male genital organ, we can state the following:
- A. it is part of the urinary ducts, being a urination organ;
- B. it is represented by the urethra;
- C. it is a pair organ;
- D. it is located above the scrotum, anterior to the pubian symphisis;
Correct Answer: B
Rationale: Step-by-step rationale for why answer B is correct:
1. The external male genital organ is represented by the urethra, which is the duct that carries urine from the bladder out of the body.
2. The urethra is responsible for both urination and ejaculation.
3. The other choices are incorrect because the external male genital organ is not part of the urinary ducts, not a pair organ, and not located above the scrotum.
Which of the following is not a source of estrogen?
- A. adrenal gland
- B. ovary
- C. pituitary
- D. follicle
Correct Answer: C
Rationale: The correct answer is C: pituitary. Estrogen is primarily produced by the ovaries, with a small amount also coming from the adrenal glands. The pituitary gland is not a direct source of estrogen production but plays a role in regulating the release of hormones that stimulate estrogen production in the ovaries. The follicle, on the other hand, is a structure within the ovary where estrogen is produced during the menstrual cycle. Therefore, C is the correct answer as the pituitary gland does not directly produce estrogen.

Which of the following structures are located inferior to the prostate on either side of the membranous urethra within the deep muscles of the perineum?
- A. bulbourethral gland
- B. Seminal vesicles
- C. Ejaculatory ducts
- D. Urethral ducts
Correct Answer: A
Rationale: The correct answer is A: bulbourethral gland. These glands are located inferior to the prostate on either side of the membranous urethra within the deep muscles of the perineum. They secrete a clear mucus-like fluid that neutralizes acidic urine in the urethra.
The other choices are incorrect:
B: Seminal vesicles are located posterior to the bladder and contribute to seminal fluid production.
C: Ejaculatory ducts connect the vas deferens to the urethra and are not located in the deep muscles of the perineum.
D: Urethral ducts are not a specific anatomical structure and do not exist in this context.
