8.
The submandibular ganglion Pg 1101 tble 9.4
a.
Receives fibres from the superior salivatory nucleus
T
b.
has a motor (parasympathetic) root that is carried with
the facial nerve
T - as written in table
c.
has a sympathetic root whose fibres carry on to supply
the ciliary muscle of the eye
F - supply submandibular and sublingual glands and appear to be secretomotor.
Cilary ganglion has parasymp fibres that supply ciliary muscle and
sphincter pupillae of eye
d.
has a sensory root whose cell bodies lie in the ganglion
of the seventh cranial nerve
F - Somatosensory cell bodies lie in ganglion of CN V3 (fifth).
There are no sensory cell bodies near CN VII
e.
distributes to the nasal mucosa
F - pterygiopalatine ganglion parasymp fibres supply blood vessels of
the nasal cavity
f.
is not involved in the salivation reflex
F - secretomotor
Overall:
Location: suspended from lingual nerve by two short roots lying on hyoglossus
muscle inf to submand duct
PNS root: Parasymp fibres join facial nerve and leave in its chorda tympani
branch which unites with the lingual nerve
Go to subling and submand glands
SNS root: Symp fibres from superior cervical ganglion come from plexus on
facial artery
Go to subling and submand glands and are secretomotor

e.
floor of third ventricle
