Question

When a stimulus from the motor neuron arrives at the motor end plate: A) there is an immediate increase in muscle fiber tension. B) the sarcolemma depolarizes. C) the distance between the Z lines begins to lengthen. D) glycogen stores in the muscle fiber are replaced. E) calcium is removed from troponin, allowing for muscle contraction to occur.

Step 1

ACh then binds to receptors on the sarcolemma, causing it to depolarize. This depolarization spreads along the sarcolemma and into the T-tubules, which triggers the release of calcium ions from the sarcoplasmic reticulum. The calcium ions then bind to troponin, Show more…
