Caudal refers to which part of the human torso?

Correct Answer: B

Rationale: Caudal refers to the bottom part of the torso. In anatomical terms, 'caudal' means situated near or toward the tail or the hind part of the body. This term is commonly used in anatomy to describe structures closer to the feet or lower part of the body. Therefore, 'Bottom' is the correct answer as it best represents the caudal region. Choices 'Top,' 'Middle,' and 'Front' do not accurately describe the caudal aspect of the human torso.

Correct Answer: B

Rationale: The correct answer is B. A cast is a hard protective device applied to protect a broken bone.

Choice D is incorrect as a cast is not an instrument used in surgery, but a medical device used for bone support.
