| 41. | These chemicals primarily affect the parasympathetic nervous system and can act as anticholinergic agents.
|
| 42. | Erection subsides when parasympathetic activity reduces to baseline.
|
| 43. | Therefore, the secretion of saliva stops ( which regulated by the parasympathetic ).
|
| 44. | Parasympathetic tone from these sources are obviously well matched to sympathetic tone in healthy people.
|
| 45. | The greater palatine parasympathetic synapse on the hard palate and regulate mucus glands located there.
|
| 46. | Conversely, parasympathetic stimulation causes contraction of the circular muscle and constriction of the pupil.
|
| 47. | The parasympathetic fibers that travel in the facial nerve originate in the superior salivary nucleus.
|
| 48. | This parasympathetic relaxation response is mediated by a release of nitric oxide ( NO ).
|
| 49. | Incoming parasympathetic nerve fibers form synapses with the dendrites of nerve cells within the ganglion.
|
| 50. | ACh is secreted by parasympathetic nerve fibers of both the short and long reflex pathways.
