Neurotransmission is the process by which nerve cells, or neurons, communicate with each other. When a neuron is activated, it releases chemical messengers called neurotransmitters into the synapse, the small gap between neurons. These neurotransmitters bind to receptors on the receiving neuron, allowing the signal to continue. This communication is essential for various functions in the body, including muscle movement, mood regulation, and cognitive processes. Different neurotransmitters, such as serotonin and dopamine, play specific roles in these functions, influencing everything from emotions to motor skills.
