State 4 characteristics of neurotransmitters?

1. Neurotransmitters are chemical messengers that transmit signals between neurons in the brain and nervous system.
2. They are released from the axon terminals of neurons in response to an electrical impulse.
3. Neurotransmitters bind to specific receptors on the receiving neuron, causing a change in the electrical activity of the cell.
4. They are involved in a wide range of physiological processes, including mood regulation, memory formation, and muscle movement.

1. Neurotransmitters are synthesized in the presynaptic neuron and stored in vesicles.
2. When an action potential reaches the synaptic terminal, it causes the vesicles to fuse with the presynaptic membrane and release their contents into the synaptic cleft.
3. Neurotransmitters bind to receptors on the postsynaptic neuron, and the postsynaptic neuron responds by generating an action potential or by changing its state of activity.
4. Neurotransmitters are removed from the synaptic cleft by re-uptake into the presynaptic neuron or by enzymatic degradation.
