An action potential travels down the axon of the pre-synaptic—sending—cell and arrives at the axon terminal. The axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse. In a chemical synapse, the electrical activity in the presynaptic neuron triggers the release of chemical messengers, the neurotransmitters.
I describe the synapse In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss synaptic transmission. At the nerve terminal, neurotransmitters are present within 35–50 nm membrane-encased vesicles called synaptic vesicles. To release neurotransmitters, the synaptic vesicles transiently dock and fuse at the base of specialized 10–15 nm cup-shaped lipoprotein structures at the presynaptic membrane called porosomes. The process by which this information is communicated is called synaptic transmission and can be broken down into four steps.

Impulse transmission through synapse is accomplished by electric current. When the impulse reaches the pre synaptic knob, the impulse itself act as stimulus for the post synaptic neuron causing depolarization. Now the action potential generate in second neuron.

Chemical synapse- through the lysosomes; Electrical synapse -through gap junctions
STEP 1. A Dendrites receive an impulse (signal) from another neuron, and they transmit the signal to the cell body.

Open the calcium channels (red) and move some calcium ions to the interior of the neuron.

Parts of the Synapse. Types. In the central nervous system, a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells.

by a chemical synapse, where the two cells do not touch and the nerve impulse needs particular molecules to bridge the gap between them. Nerve impulse travel along axon, the axon bulb . + Na+ K 2. Arrival of nerve impulse at the axon bulb changes membrane ----> Ca ++ flows into ending Ca+ Ca+ 3.
