Where do neurotransmitters get released to transmit messages to the next neuron?

Neurotransmitters are chemical messengers that transmit signals across the synapse from one neuron to another. When an electrical impulse, or action potential, travels down the axon of a neuron, it reaches the axon terminals, which are located at the end of the neuron's axon. Here, neurotransmitters are stored in vesicles and, upon receiving the signal, are released into the synaptic cleft—the small gap between the axon terminal of one neuron and the dendrites of the next neuron.

The release of neurotransmitters at the axon terminals is crucial for the communication between neurons. They bind to specific receptors on the dendrites of the receiving neuron, thereby facilitating the transmission of signals and continuing the relay of information through the nervous system. This process is fundamental to neuronal communication and underpins various functions including movement, perception, and mood regulation.

In contrast, the cell body, dendrites, and myelin sheath do not play direct roles in the release of neurotransmitters. The cell body contains the nucleus and other organelles vital for the neuron's health and functioning. Dendrites receive incoming signals but do not release neurotransmitters themselves. The myelin sheath acts as insulation for the axon, facilitating
