Whole muscles respond to stimuli in a(n) Blank______ fashion.Multiple choice question.tetanusgradedthresholdall or none

Break Down the Problem

1. Identify the correct term that describes how whole muscles respond to stimuli.
2. Evaluate the options provided: tetanus, graded, threshold, and all or none.

Relevant Concepts

• Tetanus: A sustained contraction of the muscle.
• Graded response: The strength of the muscle response can vary depending on the stimulus.
• Threshold: The minimum stimulus needed to initiate a contraction.
• All or none principle: A muscle fiber contracts fully or not at all when stimulated above a certain threshold.

Analysis and Detail

1. Tetanus refers specifically to continuous contraction and is not applicable to how muscles respond to all stimuli.
2. Graded response suggests that the response varies; however, this typically describes what happens at the level of individual muscle fibers, not whole muscle.
3. Threshold is about the minimum level of stimulus needed.
4. All or none indicates that a muscle fiber will respond completely once the stimulus reaches a sufficient threshold.

Verify and Summarize

The most appropriate term to describe the way whole muscles respond to stimuli is "all or none," as this principle holds true for muscle contractions.

Final Answer

All or none
