Answer 11

Superior Cervical Ganglia sends fibres to C1-C4 plus external carotic, cardiac plexus, pharyngeal plexus
Involved in Horner’s Syndrome

Middle Cervical Ganglia sends fibres to C5-C6 plus heart, thyroid and upper limb

Inferior Cervical Ganglia sends fibres to C7, C8, T1 plus heart and upper limb
