Neurotransmitters travel within the brain and nervous system by crossing the synapse, a small gap between neurons. They are released from the axon terminal of one neuron, travel across the synapse, and bind to receptors on the dendrites of the next neuron, transmitting signals between neurons.

Neurotransmitters are chemicals that carry signals between nerve cells in the human nervous system. When a nerve cell is stimulated, it releases neurotransmitters into the synapse, the gap between nerve cells. These neurotransmitters then bind to receptors on the receiving nerve cell, triggering a response and transmitting the signal. This process allows for communication and coordination within the nervous system.
Receptors are proteins on the surface of nerve cells that bind to specific neurotransmitters, which are chemical messengers. When a neurotransmitter binds to a receptor, it triggers a series of events that allow the nerve cell to transmit signals to other cells in the nervous system. This interaction between receptors and neurotransmitters is essential for communication within the nervous system.
Neurotransmitters are not considered hormones in the human body because they are released by nerve cells to transmit signals within the nervous system, while hormones are produced by glands and travel through the bloodstream to target organs to regulate various bodily functions.
Information travels through the nervous system via electrical signals called action potentials. These signals are generated by neurons and travel along their axons to transmit information from one part of the body to another. At synapses, chemical neurotransmitters are released to pass the signal from one neuron to the next. This process allows for communication and coordination within the body.
Proteins in the nervous system help regulate communication between neurons by acting as receptors and channels for neurotransmitters. These proteins play a crucial role in transmitting signals between neurons, allowing for proper functioning of the nervous system.
