Disorders in Reproductive System Questions
Question 1 of 5
The 16 feet long tube that is coiled and located above the
Correct Answer: A
Rationale: The correct answer is A: epididymis. The epididymis is a coiled tube located on the back of each testicle, approximately 16 feet long when unraveled. It plays a crucial role in sperm maturation and storage. The other choices, B: Vas deferens, C: Urethra, and D: Ureter, are incorrect as they are not coiled tubes located above the testicles and do not have the same function as the epididymis in sperm development and storage.
Question 2 of 5
The depression or socket in the pelvic bone into which the head of the femur articulates is called
Correct Answer: D
Rationale: The correct answer is D: Acetabulum. The acetabulum is the depression in the pelvic bone where the head of the femur articulates. This articulation forms the hip joint. The glenoid fossa (A) is found in the scapula and articulates with the head of the humerus, not the femur. The mandibular fossa (B) is located in the temporal bone and articulates with the mandible, not the femur. The jugular fossa (C) is a groove in the temporal bone for the internal jugular vein, not related to the femur articulation. Therefore, the correct choice is D as it accurately describes the anatomical structure where the femur articulates with the pelvic bone.
Question 3 of 5
The only movable facial bone is _____________.
Correct Answer: A
Rationale: The correct answer is A: Mandible. The mandible is the only movable facial bone as it forms the lower jaw and is connected to the skull by the temporomandibular joint, allowing for movements like chewing and speaking. Maxilla, Vomer, and Ethmoid are all facial bones, but they are fixed in place and do not have the same range of motion as the mandible. Maxilla forms the upper jaw, Vomer is a bone in the nasal cavity, and Ethmoid is a bone between the eyes. Therefore, the mandible is the only bone among the options that is capable of movement, making it the correct answer.
Question 4 of 5
The purpose of the urethra is to
Correct Answer: D
Rationale: The correct answer is D. The urethra is a tube that carries both urine from the bladder and semen from the reproductive system. This is essential for the excretion of waste (urine) and reproduction (semen). Choice A is incorrect because the urethra carries both urine and semen. Choice B is incorrect as the urethra carries both substances, not just semen. Choice C is incorrect because the urethra carries semen and urine separately, not as a mixture. Overall, choice D is correct because the urethra can carry both semen and urine, just not simultaneously.
Question 5 of 5
Which spermatid phase (spermiogenesis) is distinguished by the presence of PAS positive granules called pro acrosomal granules?
Correct Answer: A
Rationale: The correct answer is A: Golgi phase. During the Golgi phase of spermiogenesis, the proacrosomal granules are formed from the Golgi apparatus and are PAS positive. These granules will later contribute to the formation of the acrosome in mature sperm. The other choices are incorrect because: B: Cap phase - This phase is characterized by the formation of the acrosomal cap over the nucleus, not the proacrosomal granules. C: Acrosome phase - This phase involves the elongation and shaping of the acrosome, not the formation of proacrosomal granules. D: Maturation phase - This phase focuses on the final maturation and condensation of the sperm cell, not the formation of proacrosomal granules.
