Question 1 of 5
The tailbone is also called as
Correct Answer: C
Rationale: The correct answer is C: Coccyx. The tailbone is also known as the coccyx, which is a small triangular bone at the base of the spine. It consists of 3-5 fused vertebrae. The lumbar vertebra (A) is part of the lower back, the sacrum (B) is a large triangular bone at the base of the spine, and the cauda equina (D) is a bundle of nerves at the lower end of the spinal cord. The coccyx specifically refers to the tailbone, making it the correct choice in this context.
Question 2 of 5
The point of junction of the muscle to the bone that moves is called the ___________________.
Correct Answer: A
Rationale: The correct answer is A: Insertion. The point of junction of the muscle to the bone that moves is called the insertion because this is where the muscle attaches to the bone that it acts upon. The insertion is typically located distally in relation to the origin of the muscle. The origin, choice B, refers to the point of attachment of the muscle to the stationary bone. Choices C and D, Sheath and Fascia, are incorrect as they do not specifically refer to the point of junction of the muscle to the bone that moves.
Question 3 of 5
A surge of FSH and LH is induced in the adenohypophysis 24 hours before ovulation and the first meiotic division of the primary oocyte resumes. At what stage does the oocyte become arrested until it becomes fertilized?
Correct Answer: D
Rationale: The correct answer is D: Second meiotic division, metaphase. After the surge of FSH and LH induces the first meiotic division to resume, the oocyte becomes arrested at the metaphase stage of the second meiotic division until fertilization. This arrest allows for the completion of meiosis upon fertilization. Choices A and B are incorrect because the oocyte does not become arrested at the prophase or metaphase of the first meiotic division. Choice C is incorrect because the oocyte does not become arrested at the prophase of the second meiotic division, but rather at the metaphase stage.
Question 4 of 5
Concerning Muller’s cells, all are true except:
Correct Answer: B
Rationale: B: They are nerve cells. Rationale: Muller's cells are a type of glial cell in the retina, not nerve cells. They provide structural support and play a role in maintaining the retinal environment. Other choices are true: A) They form limiting membranes, C) They have long processes, and D) Their nuclei are in the inner nuclear layer.
Question 5 of 5
Sperm maturation occurs in the
Correct Answer: B
Rationale: The correct answer is B: epididymis. Sperm maturation occurs in the epididymis, a coiled tube located on the posterior surface of the testes. Here, sperm undergo the process of capacitation, gaining the ability to fertilize an egg. The seminiferous tubules (choice A) are responsible for sperm production, not maturation. The vas deferens (choice C) is a duct that carries mature sperm from the epididymis to the urethra, and the urethra (choice D) is a passage for both urine and sperm but not the site of sperm maturation.
