Term
the superior cervical ganglion receives sympathetic preganglionic axons from neurons in the lateral horn of ____.
Definition
T1
Term
describe the superior cervical ganglion and what it innervates
Definition
Receives sympathetic preganglionic axons from neurons in the lateral horn of T1.

Gives off the internal carotid nerve that passes onto the internal carotid artery to form the internal carotid plexus.

Provides sympathetic innervation to the face and head.
Term
what is horner's syndrome?
Definition
Damage anywhere along the sympathetic pathway, involving the T1 white ramus communicantes, the superior cervical ganglion, the preganglionic or postganglionic axons, causes Horner’s Syndrome which includes:

Miosis – small pupil
Ptosis – drooping upper eyelid
Anhidrosis – lack of sweating on affected side
Face and neck flush – redness and increased warmth due to vasodilation on affected side
Term
what is the general visceral efferent nucleus for the oculomotor nerve?
Definition
edinger-westphal nucleus in the midbrain
Term
what is the general visceral efferent nucleus of the facial nerve?
Definition
superior salivatory nucleus

lacrimal nucleus is a rostral extension of the superior salivatory nucleus
Term
what is the general visceral efferent nucleus of the glossopharyngeal nerve?
Definition
the inferior salivatory nucleus
Term
describe the edinger-westphal nucleus and what it contains
Definition
In oculomotor complex in mesencephalon

Axons in oculomotor nerve

Synapse in ciliary ganglion
Term
describe the superior salivatory nucleus and what it contains
Definition
Visceral efferent nucleus of facial nerve
Axons in greater petrosal nerve and chorda tympani
Synapse in pterygopalatine and submandibular ganglia
Term
describe the inferior salivatory nucleus and what it contains
Definition
Glossopharyngeal nerve
Axons go through the tympanic plexus and enter lesser petrosal nerve
Synapse in the otic ganglion
Term
what are the 4 parasympathetic ganglia associated with branches of the trigeminal nerve?
Definition
Ciliary – nasociliary of V1
Pterygopalatine – V2
Otic – V3
Submandibular – Lingual of V3
