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.
Excitatory neurotransmitter
A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the receiving neuron. (A neurotransmitter is a chemical messenger.)
agonists Chemical substances that mimic or enhance the effects of a neurotransmitter on the receptor sites of the next cell, increasing or decreasing the activity of that cell. Drug that enhances the effects of a particular neurotransmitter.
sensory neurones
A chemical that is released from a nerve cell which thereby transmits an impulse from a nerve cell to another nerve, muscle, organ, or other tissue. A neurotransmitter is a messenger of neurologic information from one cell to another.
Some examples of how the cell membrane of a tube worm maintains a stable environments are that: - It prevents minerals in the water from flowing into the cell. - It prevents salt from flowing in.

Excitatory neurotransmitter
binds to specific receptors on postsynaptic cell membrane
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).

neurotransmitters
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).
