Final answer:
Intercellular signaling occurs across short distances in the nervous system at a structure called a synapse. Neurotransmitters are released by the presynaptic cell and travel across the small gap between nerve cells to bind to the surface of the postsynaptic cell.
Step-by-step explanation:
Intercellular signaling occurs across short distances in the nervous system at a structure called a synapse. A synapse is the junction between nerve cells where signal transmission occurs.
In this process, chemical signals known as neurotransmitters are released by the presynaptic cell and travel across the small gap between nerve cells to bind to the surface of the postsynaptic cell, allowing the signal to be transmitted.
