What is the point of contact at which impulses are passed from one cell to another?

The point of contact at which impulses are passed from one cell to another is known as a synapse. In the nervous system, this junction allows neurotransmitters to be released from the presynaptic neuron, crossing the synaptic cleft to bind to receptors on the postsynaptic neuron, thereby transmitting the signal. Synapses can be chemical or electrical, with chemical synapses being the most common in the brain.
