Reproductive System Quizlet Anatomy Questions
Question 1 of 5
Sterilization in the male is accomplished by excising a small portion of the:
Correct Answer: A
Rationale: The correct answer is A: Vas deferens. Sterilization in males is typically done through a procedure called a vasectomy, where a small portion of the vas deferens is excised to prevent the transportation of sperm from the testicles to the urethra. The vas deferens is the duct that carries sperm from the epididymis to the ejaculatory duct. Excising a portion of the ejaculatory duct, epididymis, or seminal vesicles would not prevent the transportation of sperm, making choices B, C, and D incorrect.
Question 2 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 3 of 5
Bones that are fused across the joint space by surgery is termed as
Correct Answer: B
Rationale: The correct answer is B: Arthrodesis. Arthrodesis refers to the surgical fusion of bones across a joint space. This procedure aims to stabilize a joint by creating a bony union. Ankylosis (A) is the natural fusion of bones due to disease or injury. Arthroplasty (C) involves replacing a damaged joint with an artificial prosthesis. Arthroscopy (D) is a minimally invasive procedure to visualize and treat joint problems without open surgery. In this context, only arthrodesis specifically involves fusing bones across a joint space.
Question 4 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 5 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.
