The ________ phase of muscle contractions occurs as AChE inactivates ACh and calcium ions are returned to the sarcoplasmic reticulum.

Question

Quizplus · Accepted Answer

The relaxation phase occurs after the contraction phase and is characterized by inactivation of ACh by AChE and the return of calcium ions to the sarcoplasmic reticulum. The myogram is a recording of muscle tension over time, the latent period is the time between stimulation and the start of muscle contraction, and the contraction phase is the period of time during which the muscle is actively shortening.
