Which structure contains lysosomal-like enzymes?
- A. Sertoli cells
- B. sperm head
- C. acrosome
- D. sperm tail
Correct Answer: C
Rationale: The correct answer is C: acrosome. Lysosomal-like enzymes are found in the acrosome of sperm cells, where they help in breaking down the outer layers of the egg during fertilization. Sertoli cells (A) provide nourishment and support for developing sperm cells. The sperm head (B) contains genetic material but not lysosomal-like enzymes. The sperm tail (D) is responsible for movement and does not contain lysosomal-like enzymes. Therefore, the acrosome (C) is the structure that specifically houses these enzymes for the fertilization process.

Which ligament holds the uterus in
- A. 8 place, laterally?
- B. 25
- C. round ligament
- D. 100
Correct Answer: C
Rationale: The correct answer is C: round ligament. The round ligament holds the uterus in place laterally. It is a band of tissue that connects the uterus to the groin region. This ligament provides support and stability to the uterus during movements and changes in position.
Choice A (8 place, laterally) and Choice D (100) are nonsensical and do not correspond to any anatomical structure or location.
Choice B (25) is also incorrect as it does not exist as a ligament involved in supporting the uterus.
In summary, the round ligament is the correct choice as it is the specific ligament responsible for holding the uterus in place laterally, providing essential support and stability.
Out of the following, which is a flat bone?
- A. Patella
- B. Shoulder blade
- C. Hand bone
- D. Thigh bone
Correct Answer: A
Rationale: The correct answer is A: Patella. The patella, also known as the kneecap, is a flat bone located in the front of the knee joint. It serves to protect the knee joint and improve the leverage of the quadriceps muscles during movement. The other choices, such as the shoulder blade (B), hand bone (C), and thigh bone (D), are not flat bones. The shoulder blade is a scapula, a flat and triangular bone. The hand bone refers to the metacarpal and phalanges, which are long bones. The thigh bone is the femur, a long bone in the upper leg. The patella's unique flat shape and location make it the correct choice.
The testicle secrets the following hormones:
- A. androgenic;
- B. progesterone;
- C. testosterone;
- D. progesterone
Correct Answer: C
Rationale: Step 1: The testicles are primarily responsible for producing male sex hormones.
Step 2: Testosterone is the main male sex hormone secreted by the testes.
Step 3: Testosterone is an androgenic hormone responsible for male characteristics.
Step 4: Progesterone is a female sex hormone, not primarily secreted by the testicles.
Step 5: Therefore, the correct answer is C (testosterone).
A 29 year old married computer programmer is c/o 'something strange' going on in his scrotum. Last month he felt a lump in his left testis, and it is still there. He has had some aching in the left testis but denies pain with urination or intercourse. Denies fever, malaise, night sweats. His PMH consisted of groin surgery as a baby and a tonsillectomy as an adolescent. He eats a healthy diet, exercises, denies tobacco or drugs. On exam the penis is circumcised with no lesions. No lymphadenopathy. Palpation of his scrotum is unremarkable on the right but indicates a large mass on the left. Placing a finger through the inguinal ring on the right, you have the patient bear down. Nothing is felt. You attempt to place your finger through the left inguinal ring but cannot get above the mass. On rectal exam, his prostate is unremarkable. What disorder of the tests is most likely the diagnosis?
- A. Hydrocele
- B. Scrotal hernia
- C. Scrotal edema
- D. Varicocele
Correct Answer: B
Rationale: The correct answer is B: Scrotal hernia. The patient's presentation with a lump in the left testis, aching, and a large mass on the left side of the scrotum, along with the inability to pass a finger above the mass through the left inguinal ring, suggests a scrotal hernia. This is further supported by the fact that bearing down does not reveal anything on the right side, ruling out hydrocele and varicocele. Scrotal edema would present with more generalized swelling in the scrotum rather than a localized mass. So, the key findings here point towards a scrotal hernia as the most likely diagnosis.
