Autonomic nervous system Flashcards
From which spinal nerves do sympathetic fibres originate?
Thorocolumbar (thoracic and lumbar)
Where do the preganglionic sympathetic fibres synapse?
In or near the CNS
From which spinal nerves do parasympathetic fibres originate?
Craniosacral (brain and sacral spinal cord)
Where dot he preganglionic parasympathetic fibres synapse?
In or near the wall of the target
Name the parasympathetic ganglions of the head and where they are found
Otic ganglion - ITF
Pterygopalatine ganglion - pterygopalatine fossa
submandibular ganglion - floor of the mouth
Cilary ganglion - orbit
Where does the parasympathetic root of parasympathetic ganglion synapse?
In the ganglion
Where does the sympathetic root of parasympathetic ganglion synapse, what is its route to the ganglion?
In the superior cervical ganglion, wraps around artery and uses parasympathetic ganglion as a path
Where do the sensory routes of parasympathetic ganglion join?
Join a trigeminal branch
Where is the otic ganglion?
Behind the main trunk of V3 in the ITF
What is the pre-ganglionic parasympathetic root of the otic ganglion?
Lesser petrosal nerve (branch of IX)
Where is the post-ganglionic parasympathetic root of otic ganglion heading?
Parotid gland
What artery does the post-ganglionic sympathetic root of otic ganglion wrap around?
Middle meningeal artery
Where does the sympathetic root of otic ganglion originate?
Thoracic or lumbar spinal cord from the sympathetic chain and synapses in superior cervical ganglion
Where is the sympathetic root of otic ganglion heading?
Parotid gland
Where does the sensory root of the otic ganglion originate?
Parotid gland
