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
