What does the term "reciprocal inhibition" refer to in muscle function?

Reciprocal inhibition refers to the physiological process in which the contraction of one muscle (the agonist) results in the relaxation of its opposing muscle (the antagonist). This mechanism is crucial for coordinated movement and helps facilitate smooth and efficient muscle function. For instance, when you flex your arm, the bicep muscle contracts to flex the elbow while the tricep muscle relaxes, allowing for that movement to occur without resistance from the opposing muscle.

Understanding this concept is vital for various practices in therapeutic massage and bodywork, as it highlights the interplay between muscles during movement and the importance of balancing muscle activity. The other options do not accurately reflect the specific nature of reciprocal inhibition.
