Cervical Autonomic Nervous System Flashcards
where are the ganglions in parasympathetic nervous system situated
close to their target organ
where are the ganglia in the sympathetic nervous system located
close to the origin of the nerves
what nerves are associated with the parasympathetic nervous system
cranio-sacral
what nerves are associated with the sympathetic nervous system
thoraco-lumbar
where do preganglionic sympathetic neurones leave the spinal cord
ventral (anterior) root
where do the preganaglionic neurones in the sympathetic system synapse
cervical ganglia
what does the superior cervical ganglion supply branches via
ICA and ECA
what does cervical ganglia regulate sympathetic innervation of
eyes (pupil dilation) eyelids, lacrimal glands, carotid body, salivary glands and sweat glands
what can damage to the sympathetic trunk result in
absence of sympathetically stimulated function to the same side of head
what is horner’s syndrome
constriction of pupil, drooping of superior eyelid and absence of sweating on the face and neck
what cranial nerves are associated with parasympathetic ganglia
CN III, VII and IX
what ganglion is associated with CN III
ciliary ganglion
what ganglia are associated with CN VII
pterygopalatine ganglion and submandibular ganglion
what action is the pterygopalatine ganglion associated with
stimulates lacrimal glands and nasal mucosa
what is the submandibular ganglion associated with
submandibular gland via the chorda tympani and the sublingual gland
