In anatomical position, the palms of the hands are pronate.
True
False
The Correct Answer is False
Choice A reason: This statement is incorrect. In anatomical position, the palms face forward (supinated), not backward (pronated). Pronated palms would indicate a rotated forearm, which is not the standard anatomical reference.
Choice B reason: This is correct. Anatomical position is defined with the body standing upright, feet together, arms at the sides, and palms facing forward. This orientation ensures consistency in anatomical terminology and reference.

Correct Answer is B
Explanation
Choice A reason: While converting lactic acid to pyruvic acid is part of recovery, excess postexercise oxygen consumption (EPOC) encompasses more than just this process.
Choice B reason: This is the correct answer. EPOC refers to the additional oxygen required after exercise to restore the body to its resting state. It includes replenishing ATP and creatine phosphate stores, converting lactic acid, and restoring oxygen levels in blood and muscle.
Choice C reason: Oxygen consumption is not directly equal to glucose usage. This choice oversimplifies the metabolic relationship.
Choice D reason: Oxygen used during exercise is part of normal aerobic metabolism, not excess postexercise consumption.
Choice E reason: Oxygen taken in during contractions is part of ongoing metabolism, not the recovery phase described by EPOC.
Correct Answer is B
Explanation
Choice A reason: Myofilaments are the smallest contractile units within myofibrils, composed of actin and myosin. They do not represent bundles of muscle fibers.
Choice B reason: Fascicle is the correct term for a bundle of muscle fibers. Each fascicle is surrounded by perimysium and contains multiple muscle cells.
Choice C reason: Myofibrils are microscopic structures within individual muscle cells that contain the contractile machinery. They are not bundles of muscle fibers.
Choice D reason: Whole muscle refers to the entire organ composed of multiple fascicles, connective tissues, blood vessels, and nerves. It is a larger structure than a bundle of muscle fibers.
