If a woman has a tumor secreting large amounts of estrogen from the adrenal gland, which of the following will occur?

  • A. Progesterone levels in the blood will be very low
  • B. Her luteinizing hormone secretion rate will be totally suppressed
  • C. She will not have normal menstrual cycles
  • D. Her bones will be normally calcified
Correct Answer: B

Rationale: Correct Answer: B - Her luteinizing hormone secretion rate will be totally suppressed

Rationale:
1. The tumor secretes large amounts of estrogen, which can lead to negative feedback on the hypothalamus and pituitary gland.
2. Luteinizing hormone (LH) is crucial for ovulation and normal menstrual cycles.
3. High estrogen levels can suppress LH secretion, disrupting ovulation and menstrual cycles.

Summary of other choices:
A: Progesterone levels may actually be elevated due to the tumor-induced high estrogen levels.
C: The disruption of LH secretion can lead to abnormal menstrual cycles.
D: High estrogen levels can lead to bone loss due to inhibition of bone formation and increased bone resorption.

Which of the following tissues secrete proteolytic enzymes to liquefy semen?

  • A. bulbourethral gland
  • B. urethra
  • C. prostate
  • D. testis
Correct Answer: C

Rationale: The correct answer is C: prostate. The prostate gland secretes proteolytic enzymes such as prostate-specific antigen (PSA) to liquefy semen. This aids in sperm mobility and overall fertility. The other choices are incorrect because:
A: bulbourethral gland secretes a clear fluid to lubricate the urethra during sexual arousal.
B: urethra is a passageway for urine and semen but does not secrete proteolytic enzymes.
D: testis produces sperm cells but does not secrete enzymes to liquefy semen.

The medical term expressing suture of the neck of the uterus is __________

  • A. cervicography
  • B. perineorrhaphy
  • C. cervicorrhapy
  • D. cervicorrhexis
Correct Answer: C

Rationale: The correct answer is C: cervicorrhaphy. "Cervico-" refers to the neck of the uterus, and "-rrhaphy" means suture. Therefore, cervicorrhaphy is the correct term for the procedure of suturing the neck of the uterus.
A: Cervicography is a diagnostic imaging technique, not a procedure for suturing.
B: Perineorrhaphy involves suturing the perineum, not the neck of the uterus.
D: Cervicorrhexis refers to cutting or incising the neck of the uterus, not suturing it.

What does line “G” point to?

  • A. Dartos muscle
  • B. Cremaster muscle
  • C. Fascia
  • D. Tunica albuginea
Correct Answer: B

Rationale: The correct answer is B: Cremaster muscle. Line "G" points to the cremaster muscle because it is the muscle responsible for raising and lowering the testes to regulate their temperature. This muscle is located within the spermatic cord and is crucial for maintaining optimal conditions for sperm production. The other choices are incorrect because:
A: The dartos muscle is responsible for wrinkling the scrotal skin but is not depicted by line "G."
C: Fascia refers to connective tissue and does not match the description of the muscle shown by line "G."
D: The tunica albuginea is a fibrous coat around the testis but is not represented by line "G."

Choose the CORRECT match. Animals Fertilization Embryonic development

  • A. Dog Internal Oviparity
  • B. Duck External Viviparity
  • C. Frog External Oviparity
  • D. Cat Internal Ovoviviparity
Correct Answer: C

Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because:
A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs.
B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally.
D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
