Superior Cervical

1
SYMPATHETIC GANGLIA
Cell bodies start here
then synaspe here
Preganglionic fibers run here
Continue on as postganglionic fibers
and end here!
Superior Cervical ganglion
Ventral root ? vpr ? white rami ? sympathetic
trunk--?
Lateral horn T1-T4
Gray rami
C1-C4 Also to external carotid Cardiac
plexus Pharyngeal plexus
Horners Syndrome Cut before Superior cervical
ganglion and present with Meiosis (pinpoint
pupil) Anhydrosis (cant sweat) Partial ptosis
(upper lid droops)
Middle Cervical ganglion
Ventral root ? vpr ? white rami ? sympathetic
trunk?
Lateral horn T1-T4
Gray rami
C5, C6 Also to heart, thyroid upper limb
Inferior Cervical ganglion
Ventral root ? vpr ? white rami ? sympathetic
trunk?
Lateral Horn T1-T4
Gray rami
C7, C8, T1 Also to heart upper limb
Fuses with first thoracic ganglion stellate
ganglion!
2
Parasympathetic Ganglia
Pupillae sphincter- constricts pupil Ciliary
muscle- rounds up lens
Edinger-Westphal nucleus
Ciliary ganglion
Short ciliary n.
III
Superior Salivatory Nucleus
Chorda tympani n. carries parasympathetic fibers
Sublingual gland Submandibular gland
VII
Submandibular ganglion
N. To pterygoid canal
Hitchhikes on maxillary n.
Greater petrosal n. Carries parasympathetic fibers
Lacrimal gland Nasal gland Palatine gland
Superior Salivatory Nucleus
Pterygopalatine ganglion
VII
Deep petrosal n. Carries sympathetic fibers
Warning Sympathetic does not synapse here!
Hitchhike on auriculotemporal n.
Inferior Salivatory Nucleus
Otic ganglion
IX
Partotid gland
3
SENSORY GANGLIA
Semilunar Ganglion aka Trigeminal
V
V1, V2, V3
Chorda tympani carries sensory fibers
Skin around external acoustic meatus Taste-
anterior 2/3 of tongue
Geniculate ganglion
