Question: Which of the following is the correct order of events that occur at a cholinergic synapse?
Answer: The correct order of events that occurs in the cholinergic synapse is 4,1,3,2
Explanation:
cholinergic synapse are distributed all over the body and they aid in transmitting electrical signals from one cell to another. Acetylcholine is used as the neurotransmitter. This can be from a muscle cell to a nerve cell or from nerve cell to nerve cell. The series of events that takes place at this synapse includes the following steps:
- Axon terminal depolarizes.
- Extracellular calcium enters the axon terminal, triggering the exocytosis of acetylcholine
- Acetylcholine binds to receptors and depolarizes the postsynaptic membrane
- Acetylcholine is removed by acetylcholinesterase.
