Card 27 / 34: What happens at the NMJ after synaptic vesicles fuse with the motor end plate?
A) Impulse travels T-tubules and sarcoplasmic reticulum
B) Acetylcholine released via process of exocytosis.
C) Acetylcholine binds with receptor sites on motor end plate, causing depolarization of motor end plate and sarcolemma.
D) Calcium ions bind to troponin.
E) Binding of myosin to actin changes conformation of the myosin head, resulting in release of ADP and Pi.
