Question

Quizplus · Accepted Answer

Acetylcholine binds to receptors on the motor end plate (3), leading to end-plate potentials that trigger action potentials (1). These action potentials are conveyed into the interior of the cell by transverse tubules (2), which then cause the release of Ca²⁺ from the sarcoplasmic reticulum (4).
