What does concave mean?

Correct Answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

Correct Answer: B

Rationale: The correct answer is B. Distal means further away from the point of attachment. This term is commonly used in anatomy to describe the location of a body part relative to the point of attachment or the trunk. Choice A is incorrect because it describes the term Proximal, which means closer to the point of attachment. Choice C is incorrect as it describes the term Medial, which means toward the middle of the body. Choice D is incorrect as it describes the term Superficial, which means on or near the surface.

Correct Answer: B

Rationale: Exposure refers to coming into contact with external elements. Choice A is incorrect as exposure does not imply protection but rather contact. Choice C, absorption, refers to the process of soaking up or taking in something. Choice D, isolation, means being separated or kept apart from others, which is not synonymous with exposure.

Correct Answer: B

Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.
