Whole muscles respond to stimuli in a(n) Blank______ fashion.Multiple choice question.tetanusall or nonegradedthreshold

1. Break Down the Problem

The question is asking for the term that describes how whole muscles respond to stimuli. It provides multiple choice options: tetanus, all or none, graded, and threshold.

2. Relevant Concepts

• Tetanus: A sustained muscle contraction where the muscle does not relax between stimuli.
• All or None: A principle stating that a muscle fiber will either completely contract or not at all.
• Graded: Refers to the ability of muscle contractions to vary in strength.
• Threshold: The minimum stimulus required to trigger a response.

3. Analysis and Detail

• Whole muscles respond to stimuli in a graded fashion, meaning that the strength of the contraction can vary with the strength of the stimulus. However, the term "graded" generally applies more specifically to how individual muscle fibers respond, while "all or none" applies to individual muscle fibers. Since the question specifies "whole muscles," "tetanus" might refer to a state of sustained contraction but does not precisely capture the nature of responsiveness. The best fit in context is "graded."

4. Verify and Summarize

Considering the definitions and application, the most appropriate answer for how whole muscles respond to stimuli is "graded."

Final Answer

Graded.
