Neurotransmitter

neurotransmitter

Any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. Among the many substances that have the properties of a neurotransmitter are acetylcholine, noradrenaline, adrenaline, dopamine, glycine, y aminobutyrate, glutamic acid, substance P, enkephalins, endorphins and serotonin.

The Heart

... via neuromuscular junctions so any chance in the potential of the node will affect the action of the muscle. Therefore Ach (acetylcholine) is a neurotransmitter that's inhibitory in this situation and slows down heart rate by slowing the rate of action potentials that are fired, thus slowing ...

Re: human physiology qu please help

... example listed above is a great one. Just to fill in SOME of the details: When there is an action potential in a presynaptic neuron, it results in Neurotransmitter release from the axon terminals. The neurotransmitter (for example Acetylcholine) binds to receptors of the postsynaptic nerve cell. ...
