nerve fibers of n. vagus
motor, sensory, parasympathetic
runs with
sympathetic nerve, common carotid and external jugular
what laryngeal nerve joins distal ggl
n. laryngea cranialis
on which nerve can you find the ggl. cervicale craniale
tr. sympatheticus
what are the branchings of a. maxillaris caud -> rostr
continuation of external carotid
a. auricularis caudalis
a. parotidea
a. temporalis superficialis (transv. faciei, aur rostr)
a. alveoaris inferior
continues as infraorbital(dors/lat nasi)
where does the n. laryngea cranialis enter the larynx
for. thyroideus
what cells are found in sinus caroticum and what are their function
chemoreceptors: sense decrease in BP
baroreseptors: (stretch) sense BP change
dissection
- dissect digastricus - acc is under
- clean caudal to ear
- find trachea - clean the vessels/nerves caud -> cran
- find gl. parotidea (under sternothyroideus)
another name for ggl in vagus nerve
nodosi prox dist
vagus group
IX - glossopharyngeus (most rostr and deep)
X - vagus (along common carotid)
XI - accessory (under digastricus, under ala atlantis)
fibers of IX - glossopharyngeus
motor and sensory
where is IX located
just caudal to stylohyoid (remove it)
