1. Superior Cervical ganglion Middle Cervical ganglion Inferior Cervical ganglion Gray rami C1-C4 Also to external carotid Cardiac plexus Pharyngeal plexus C5, C6 Also to heart, thyroid & upper limb C7, C8, T1 Also to heart & upper limb Lateral horn T1-T4 Ventral root  vpr  white rami  sympathetic trunk--  Lateral horn T1-T4 Lateral Horn T1-T4 Ventral root  vpr  white rami  sympathetic trunk  Fuses with first thoracic ganglion = stellate ganglion! Horner’s Syndrome: Cut before Superior cervical ganglion and present with… Meiosis (pinpoint pupil) Anhydrosis (can’t sweat) Partial ptosis (upper lid droops) SYMPATHETIC GANGLIA Cell bodies start here… Preganglionic fibers run here… …then synaspe here Continue on as postganglionic fibers… …and end here!

2. Pterygopalatine ganglion Otic ganglion Submandibular ganglion Ciliary ganglion Lacrimal gland Nasal gland Palatine gland Hitchhikes on maxillary n. Superior Salivatory Nucleus VII Greater petrosal n. Carries parasympathetic fibers N. To ptery goid canal Deep petrosal n. Carries sympathetic fibers Pupillae sphincter- constricts pupil Ciliary muscle- rounds up lens Short ciliary n. III Edinger- Westphal nucleus Warning: Sympathetic does not synapse here! Sublingual gland Submandibular gland Superior Salivatory Nucleus VII Chorda tympani n. carries parasympathetic fibers Hitchhike on auriculotemporal n. Partotid gland Inferior Salivatory Nucleus IX Parasympathetic Ganglia

3. Geniculate ganglion Semilunar Ganglion aka Trigeminal V V1, V2, V3 VII Chorda tympani carries sensory fibers Skin around external acoustic meatus Taste- anterior 2/3 of tongue SENSORY GANGLIA
