What do synaptic terminals do
Presynaptic neuron sends message to postsynaptic neuron by secretion of chemical messengers known as neurotransmitters: this is because at synapse the two neurons are not in direct physical contact.

Biology Coordination and Control Nerves and Hormones. Mandira P. Jan 7, Explanation: Presynaptic neuron sends message to postsynaptic neuron by secretion of chemical messengers known as neurotransmitters: this is because at synapse the two neurons are not in direct physical contact.
Dendrites bring information to the cell body and axons take information away from the cell body. Information from one neuron flows to another neuron across a synapse. The synapse contains a small gap separating neurons. The synapse consists of:. Hear IT! For communication between neurons to occur, an electrical impulse must travel down an axon to the synaptic terminal. At the synaptic terminal the presynaptic ending , an electrical impulse will trigger the migration of vesicles the red dots in the figure to the left containing neurotransmitters toward the presynaptic membrane.
The vesicle membrane will fuse with the presynaptic membrane releasing the neurotransmitters into the synaptic cleft. Until recently, it was thought that a neuron produced and released only one type of neurotransmitter.
This was called "Dale's Law. Google Scholar. Neher E and Sakaba T Multiple roles of calcium ions in the regulation of neurotransmitter release. Sheng M and Hoogenraad CC The postsynaptic architecture of excitatory synapses: a more quantitative view.
