Question

Quizplus · Accepted Answer

Shortening of the sarcomere is the final event in skeletal muscle contraction. Prior to this, there must be activation of the NM receptors by ACh, release of neurotransmitter (ACh) from the somatic motor neuron, and release of calcium from the sarcoplasmic reticulum.
