With respect to ejaculation which of the following statements is incorrect.
- A. ejaculation is the result of para-sympathetic stimulation
- B. ejaculation results from the summation of synaptic potentials
- C. during ejaculation semen is expelled by rapid contraction of the urethral smooth muscle
- D. ejaculation results is the discharge of sperm, seminal vesicle and prostatic secretions
Correct Answer: A
Rationale: The correct answer is A because ejaculation is primarily controlled by the sympathetic nervous system, not the para-sympathetic system. The sympathetic nervous system triggers the contraction of smooth muscles to allow for ejaculation. Choice B is incorrect because ejaculation is not a result of summation of synaptic potentials, but rather a coordinated response. Choice C is incorrect because semen is expelled by rhythmic contractions of the pelvic floor muscles, not the urethral smooth muscle. Choice D is incorrect because ejaculation involves the discharge of sperm, seminal vesicle, prostatic secretions, and other fluids from the reproductive system.
This tiny gland produces a secretion that is similar to a large lysosome and that cleanses the male urethra of assists penetration of the egg is called traces of acidic urine prior to the ________.
- A. flagellum
- B. prostate
- C. midpiece
- D. bulbo-urethral gland
Correct Answer: D
Rationale: The correct answer is D: bulbo-urethral gland. This gland produces a clear secretion that neutralizes traces of acidic urine, lubricates the urethra, and assists in sperm motility. The other choices are incorrect because:
A: Flagellum is a structure on sperm cells for propulsion.
B: Prostate produces seminal fluid but does not cleanse the urethra.
C: Midpiece is a part of the sperm cell that contains mitochondria for energy production, not a gland.
The vascularization of the Fallopian tubes is provided by branches off the following artery:
- A. uterine;
- B. ovarian;
- C. external iliac;
- D. abdominal aorta;
Correct Answer: A
Rationale: The correct answer is A: uterine artery. The uterine artery provides blood supply to the Fallopian tubes. It arises from the internal iliac artery and gives off branches that vascularize the tubes. The ovarian artery primarily supplies blood to the ovaries, not the Fallopian tubes. The external iliac artery supplies the lower extremities, not the reproductive organs. The abdominal aorta is a main artery that gives rise to multiple branches supplying various organs, but it does not directly supply the Fallopian tubes.
_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase
- B. Trypsin
- C. Helicase
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Hyaluronidase. This enzyme is released by the sperm to help penetrate the outer layer of the egg during fertilization. Hyaluronidase specifically breaks down hyaluronic acid present in the cumulus cells surrounding the egg. Trypsin is a digestive enzyme found in the pancreas, not involved in sperm function. Helicase is an enzyme involved in DNA replication and repair, not released by sperm. "None of the above" is incorrect as hyaluronidase is indeed released by the sperm.
Sella turcica is a __________ in the sphenoid bone in which
- B. Groove
- C. Projection
- D. Depression
Correct Answer: D
Rationale: The correct answer is D: Depression. Sella turcica is a saddle-shaped depression in the sphenoid bone that houses the pituitary gland. It is not a groove (B) as it is a deeper concavity. It is not a projection (C) as it is a recessed area rather than a raised structure. It is not a foramen (A) as it is a hollowed-out area rather than a small opening. Therefore, the most accurate description of sella turcica is a depression in the sphenoid bone.
