Where is the synapse located
Synapses are microscopic gaps that separate the terminal buttons of one neuron from receptors (usually, located on the dendrites) of another neuron.Where two structures or entities come together, they form a synapse.The usual source of this current is the potential difference generated locally by the action potential (see chapter 3).Electrical synapses thus work by allowing ionic current to flow passively through the gap junction pores from one neuron to another.This is how signals are transmitted through the nervous system.
.in many synapses, the presynaptic part is located on an axon and the postsynaptic part is located on a dendrite or soma.Synapses are essential to the transmission of nervous impulses from one neuron to another.As we discuss synaptic transmission, we will focus mainly on axodendritic synapses, in which the presynaptic terminal synapses on the dendrites of the postsynaptic cell.Synapses are the junctions between two or more neurons where impulses pass from one neuron to others.One cubic cm of brain cortex have about one billion synapses, probably.
They are between two neurons.At a chemical synapse each ending, or terminal, of a nerve fibre (presynaptic fibre) swells to form a knoblike.It is referred to as the synaptic cleft or synaptic gap.In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
