The primary function of neurotransmission in the nervous system is to facilitate communication between neurons, allowing for the transmission of signals throughout the body. This process involves the release of neurotransmitters from one neuron into the synaptic cleft, where they bind to receptors on the receiving neuron, propagating the nerve impulse. Neurotransmission is essential for various functions, including muscle movement, sensory perception, and cognitive processes. Any disruption in this process can lead to neurological disorders, highlighting the importance of understanding neurotransmission for both basic science and medical interventions.
