Nitric oxide is a unique, gaseous free radical that is an important physiologic mediator for autonomic functions such as vasodilation, neurotransmission , and intestinal peristalsis.
The active ingredients in this were alkaloids of belladonna, which we now know had the effect of inhibiting cholinergic neurotransmission and thereby reflex bronchoconstriction.
Cnidarians contain chemical synapses and release neurotransmitters , including biogenic amines and peptides.
A neuron generates an electrical impulse, causing the cell to release its neurotransmitters .
We provide the first evidence that tachykinin neurokinin - 3 receptors regulate human bronchial parasympathetic ganglion neurotransmission by activation of a peripheral reflex.
Excitatory neurotransmitters transfer an impulse to the next cell.
Nerve impulses are transmitted at synapses by the release of chemicals called neurotransmitters .
Postsynaptic proteins receive the neurotransmitters released by presynaptic proteins.
Maintaining a higher level of neurotransmitters improves neurotransmission - the sending of those nerve impulses - which, in turn, improves your mood.
Recent evidence suggests that carbon monoxide is a neurotransmitter involved in neurotransmission between ICC and smooth muscle cells.
