What happens at a chemical synapse?
How does a chemical synapse affect a postsynaptic cell?
Why is there no gap between electrical and chemical synapses?
Does a chemical synapse make direct contact between two neurons?
There actually are certain neurons where there isn't any gap--electrical synapses connect directly because electrical signals cannot travel through a gap. Chemical synapses need the synaptic cleft so that chemicals can be secreted by one neuron and taken in by the next.

Chemical. At a chemical synapse, a signaling molecule is released by the presynaptic cell to influence the postsynaptic cell by binding to postsynaptic receptors. Since chemical synapses do not rely on a direct physical protein “tunnel” to connect the two neurons, the distance between the two cells can be much larger.
Feb 28, 2021 · Chemical Synapse; Electrical Synapse; Contributors and Attributions; The synapse or “gap” is the place where information is transmitted from one neuron to another. Synapses usually form between axon terminals and dendritic spines, but this is not universally true. There are also axon-to-axon, dendrite-to-dendrite, and axon-to-cell body ...
Feb 4, 2008 · Description. This animation shows how neurons send and receive signals to communicate with one another at contact points called synapses. Electrical impulses travel from neuron to neuron to transfer information. When an electrical impulse reaches the end of a neuron, it triggers the opening of channels that release calcium ions.
