Parasympathetic CN nuclei Flashcards
What are the functions of CN X parasympathetics in the digestive system (up to descending colon)?
Increase peristalsis and contractility, increase secretions, relax spinchters
Where do CN VII parasympathetics go after superior salivatory nucleus?
Pterygopalatine ganglion –> lacrimal gland Submandibular ganglion –> submandibular + sublingual glands
Name of CN IX nucleus
Inferior salivatory nucleus
Function of CN III parasympathetics
Constriction via pupillary constrictor muscle Accommodation via ciliary muscle
Name of CN X nucleus
Dorsal motor nucleus of X
Otic ganglion
CN IX parasympathetics
What are the functions of the parasympathetics in the sacral plexus?
Increase peristalsis/motility/contractility and secretions of descending colon and down, increase motility of ureters, contraction of detrussor, erection
Submandibular ganglion
CN VII
What is the parasympathetic innervation to the gut below the descending colon?
S2-S4
Location of EWN
Midbrain
What are the functions of CN X parasympathetics in the heart and lungs?
Slow HR, decrease CO, constrict bronchioles
Where do CN III parasympathetics go after Edinger-Westphal nucleus?
Ciliary ganglion –> pupillary constrictor muscle and ciliary muscle
Location of superior salivatory nucleus
Pons
Edinger-Westphal nucleus
CN III
Location of dorsal motor nucleus of X
Medulla
Ptergyopalatine ganglion
CN VII
Location of inferior salivatory nucleus
Medulla
Ciliary ganglion
CN III parasympathetics
Where do CN IX parasympathetics go after the inferior salivatory nucleus?
Otic ganglion –> partoid gland
Name of CN III nucleus
Edinger-Westphal
Where do CN X parasympathetics go after dorsal motor nucleus of X?
Heart, lungs, gut up to descending colon
Name of CN VII nucleus
Superior salivatory nucleus
