Final answer:
Synaptic transmission involves neurotransmitter binding to ion channels, leading to membrane potential changes and impulse formation, aiding rapid communication.
Explanation:
Transmission of Signals at Chemical Synapses
One key aspect of synaptic transmission is the binding of neurotransmitters to ligand-gated ion channels on the postsynaptic membrane, causing depolarization or hyperpolarization. The neurotransmitter is then removed from the synaptic cleft either enzymatically or through reuptake, allowing the postsynaptic membrane to reset for further signaling.
When a neurotransmitter like acetylcholine binds to its receptor on the postsynaptic cell, ion channels open, changing the membrane potential and initiating impulse formation in the next neuron or receptor cell. This process ensures rapid communication between neurons for various physiological functions.
