Instead a space called the synaptic cleft exists between the presynaptic terminal and the postsynaptic membrane. V Electrical synapses are fast. These synapses communicate using chemical messengers.

TF At a neuronal synapse facilitation of a post-synaptic response results because of an accumulation of calcium ions from previous pre-synaptic cell action potentials. One neuron can form synapses with many others. Select one of the following.

There are two types of synapses. They allow the nervous system to connect. The fundamental bases for perceiving electrical synapses comes down to the connexons that are located in the gap junction between two neurons.
