The general meaning of the term "corpus" is best described by which of the following?

Correct Answer: B

Rationale: The correct answer is B: Body. Corpus commonly refers to a collection of written or spoken texts, which together form a body of work. "Body" is the best choice as it encompasses the idea of a collection or group of related items. A is incorrect as it refers specifically to the abdomen, not the general term. C, Death, and D, Head, are unrelated to the general meaning of "corpus" as they do not convey the idea of a body or collection.

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.

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.

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.

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.
