Explanation:
Neurons transmit nervous impulses. These cells are composed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli (information) from other cells, and an axon that is a long structure capable of conducting the electrochemical signals. Every neuron forms <em>connections with other neurons</em>. These connections are known as <em>synapsis</em>. As it happens in every synapsis between cells when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area and binds to its receptors in the postsynaptic membrane. This binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it.
