postganglionic การใช้

• The postganglionic parasympathetic fibers leave the pterygopalatine ganglion in several directions.
• Stretch receptors cause postganglionic neurons to release norepinephrine ( NE ).
• A preganglionic fibre may synapse to 15-20 postganglionic fibres.
• The postganglionic neuron will then synapse at the target organ.
• Some believe that chromaffin cells are modified postganglionic CNS fibers.
• These postganglionic neurons provide parasympathetic innervation to the submandibular and sublingual glands.
• Postganglionic cell refers to parasympathetic neurons which receive information from the preganglionic fibers.
• The " sympathetic postganglionic fibers " originate from the superior cervical ganglion.
• The postganglionic nerve then proceed to innervate their targets ( pelvic visceral organs ).
• The " parasympathetic root ( inferior ) " carries postganglionic fibers to the parotid gland.
• Postganglionic parasympathetic fibers will release acetylcholine causing the constriction of the smooth muscle layer surrounding the bronchi.
• Once inside the prevertebral ganglia, the individual neurons comprising the nerve synapse with their postganglionic neuron.
• The completion of the reflex circuit by vagus efferents leads to the stimulation of postganglionic muscarinic nerves.
• The sacral sympathetic nerves contain a mix of preganglionic and postganglionic sympathetic fibers, but mostly postganglionic.
• The sacral sympathetic nerves contain a mix of preganglionic and postganglionic sympathetic fibers, but mostly postganglionic.
• The two exceptions mentioned above are postganglionic neurons of sweat glands and chromaffin cells of the adrenal medulla.
• Postganglionic cells have their cell bodies in the ganglia and send their axons to target organs or glands.
• The first synapse ( preganglionic neuron to postganglionic neuron ) is mediated by nicotinic receptors activated by acetylcholine.
• There are the muscarinic signs, which are effects that are similar to stimulation on postganglionic parasympathic nerves.
• Similar to the paravertebral ganglia, the prevertebral ganglia are the nodules where preganglionic neurons synapse with their postganglionic counterparts.
