Solution: Explain the sequence of events that allows a pre-synaptic cell to communicate with a post-synaptic cell.

Problem

Explain the sequence of events that allows a pre-synaptic cell to communicate with a post-synaptic cell.

Solution

Communication with pre-synaptic and post-synaptic cells starts when action potential reaches the axon terminal which depolarizes the membrane. This activates calcium channels allowing Ca2+ ions to flow inside the membrane.
