Question
Chapter 12, Problem 19DYKB
Summary Introduction
To explain:
The mechanism for the release of neurotransmitter from the synaptic knob.
Concept introduction:
Neurotransmitters are chemical substances which are released by the axon terminals when nerve impulses arrive. These neurotransmitters are stored in synaptic vesicles. These vesicles then fuse with the sending membrane which results in the release of neurotransmitter into the synaptic cleft.

Discuss the different mechanisms for removing neurotransmitter from the synaptic cleft.
In neurology, please explain the relationship between extraceullalar calcium concentration and post synaptic potential. does higher extra cellular calcium concentration means bigger change in postsynaptic potential and lower extra cellular calcium concentration means smaller change in postsynaptic potential?
Please explain in a few sentences.
