inhibitory transmitters
Excitatory neurotransmitter
uptake inhibitors Well, the Gamma-aminobutyric acid (GABA) inhibitory neurotransmitter acts through a negative feedback system to block the transmission of a signal from one cell to another. It is important for balancing the excitation in the brain. Benzodiazepines (anti-anxiety drugs, e.g. Lexapro, Valium.) work on the GABA receptors of the brain, inducing a state of relaxation. Hope this helped.
neurotransmitters
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
Histamine is a neurotransmitter produced by basophils (a type of white blood cell).
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.

neurotransmitter
A neuron sends a message, or neurotransmitter, to the muscle cell to tell it what to do. To get the message, the receiving cell must have a receptor. Oddly, the unstable protein rapsyn is responsible for anchoring the receptor so it's properly positioned to catch the message.
It is important for the neurotransmitter to be deactivated soon after its release to prevent continuous stimulation of the receiving cell, which could lead to overexcitation or desensitization. Deactivation helps regulate the signaling process and maintain proper communication between neurons in the brain.
Slightly oversimplifying it:electrically through the cell dendrites, body, and axon via trans-membrane ion transportchemically across the synapse via emptying of vacuoles of neurotransmitter by the sending cell into the synapse and binding of this neurotransmitter to matching receptors on the receiving cell, causing it to fire electricallyrepeat from cell to cell down the length of the nerve
