Detailed explanation-1: -Chemical synapses use the release of chemical neurotransmitters to propagate signals from one neuron (presynaptic) to another (postsynaptic).
Detailed explanation-2: -synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
Detailed explanation-3: -Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron-another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
Detailed explanation-4: -Neurotransmitters are chemical signals that diffuse across the synapse and attach to receptors on the dendrites of the receiving neuron.
Detailed explanation-5: -These spherical organelles are filled with one or more neurotransmitters, the chemical signals secreted from the presynaptic neuron, and it is these chemical agents acting as messengers between the communicating neurons that gives this type of synapse its name.
