Question 1 of 5
Bone is partially broken, it breaks on one surface and bends on another is known as ________________.
Correct Answer: B
Rationale: The correct answer is B: Greenstick fracture. This type of fracture occurs in children due to their bones being softer and more flexible. In a greenstick fracture, the bone is partially broken, breaking on one surface while bending on the other. This happens because children's bones have more collagen and less mineral content, making them more likely to bend rather than break completely. A: Colles fracture is a specific type of wrist fracture where the distal radius is broken. C: Impacted fracture occurs when the broken ends of the bone are driven into each other. D: Compression fracture involves the bone being crushed or compressed, usually seen in the spine.
Question 2 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 3 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 4 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 5 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.
