| 11. | Note that the parasympathetic nervous system is primarily directed toward the heart.
|
| 12. | The smooth muscle constricts under parasympathetic innervation and relax under sympathetic innervation.
|
| 13. | The bronchial spasm is due to the activation of parasympathetic nervous system.
|
| 14. | Preganglionic parasympathetic fibres exit the geniculate ganglion as the greater petrosal nerve.
|
| 15. | They contain both preganglionic parasympathetic fibers as well as visceral afferent fibers.
|
| 16. | These postganglionic neurons provide parasympathetic innervation to the submandibular and sublingual glands.
|
| 17. | Waon therapy increases parasympathetic activity and decreases the sympathetic activity.
|
| 18. | Nerve fibres of the parasympathetic nervous system arise from the central nervous system.
|
| 19. | These parasympathetic to the lacrimal gland control tear production.
|
| 20. | The second parasympathetic branch that leaves the facial nerve is the chorda tympani.
