Describe what happens at a synapse
WebSynapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal. WebA chemical synapse does not make direct contact between the two neurons. The presynaptic terminal and the postsynaptic membrane are separated by the synaptic cleft. …

Did you know?
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. Synapses are essential to the transmission of nervous impulses from one neuron to another. Neurons are specialized to pass signals to individual target cells, and synapses are the means by which they do so. At a synapse, the plasma membrane of the signal-passing neuron (the presyn…
