Which of the following statements are true of the neuromuscular junction? (Read carefully and select all the correct statements.)
A.
A synapse is the space between two muscle fibers.
B.
Acetylcholine is released from vesicles in the sarcolemma.
C.
The axon terminal is the end of a sensory neuron.
D.
Acetylcholine makes the sarcolemma more permeable to calcium ions.
E.
Cholinesterase is an enzyme that destroys acetylcholine so that the impulse will continue at the same strength.
F.
The receptors for acetylcholine are in the sarcolemma.
Place the events at the neuromuscular junction in the order in which they occur:
1. release of acetylcholine (ACh)
2. activation of ACH receptors on the motor endplate
