Put these events in the correct chronological sequence:
1) End-plate potentials trigger action potentials.
2) Transverse tubules convey potentials into the interior of the cell.
3) Acetylcholine binds to receptors on the motor end plate.
4) Ca²⁺ is released from the sarcoplasmic reticulum.

Question

Quizplus · Accepted Answer

The correct chronological sequence of events is: 3) Acetylcholine binds to receptors on the motor end plate, 1) End-plate potentials trigger action potentials, 2) Transverse tubules convey potentials into the interior of the cell, and 4) Ca²⁺ is released from the sarcoplasmic reticulum. This is because the binding of acetylcholine to receptors on the motor end plate initiates a depolarization of the muscle fiber, which leads to the release of calcium from the sarcoplasmic reticulum, and ultimately leads to muscle contraction mediated by the action potentials propagating through the transverse tubules.
