What is the primary role of neurotransmitters?

The primary role of neurotransmitters is to send communication across synaptic clefts. Neurotransmitters are chemical messengers that transmit signals from one neuron (nerve cell) to another or from neurons to other types of cells such as muscle cells or gland cells. They are released from the presynaptic neuron into the synaptic cleft and bind to specific receptors on the postsynaptic neuron, facilitating various physiological responses and contributing to complex processes such as mood regulation, cognition, and motor function.

This mechanism is essential for the proper functioning of the nervous system, enabling rapid communication between neurons and influencing numerous bodily functions. The intricate balance and interaction of neurotransmitters play a crucial role in maintaining mental health and managing psychiatric disorders.
