Question

question 6 (1 point) upon arrival of an action potential towards the axon terminal, which of the following will happen next? acetylcholinesterase is released into the synaptic cleft action potential will travel across the synaptic cleft and spread across the sarcolemma of the muscle fiber action potential will open the voltage - gated sodium channels acetylcholine is released from vesicles through exocytosis

Explanation:

When an action potential reaches the axon terminal, it triggers the release of acetyl - choline from synaptic vesicles via exocytosis into the synaptic cleft. This is a key step in neuromuscular junction communication.

Answer:

Acetylcholine is released from vesicles through exocytosis
