Sympathetic NS Flashcards
Where is the sympathetic outflow found
T1-L3 in lat grey horn
How long are the pre and post sympathetic fibres
Short pre
Long post
What are the NT of the pre on post ganglionic receptors
Pre- Ach
Post- NE
What levels run to the superior cervical ganglion and what does it run to
T1-3 to sup cervical ganglion and then to carotid plexus
What does the carotid plexus run to (4)
Dialator puliple (dilation)
Cilliary mm (accomidation)
Salivary glands (thick mucus)
Lacrimal (less)
What makes up the cardiac plexus (lvls)
T1-4
What are the end organs of the cardiac plexus + effects
Heart (increase)
Esophageal (decrease peristalsis)
Lungs (dilation of bronchioles)
What are the lvls of the Greater splanchnic nerve
T5-9
What ganglion does the GSN go to
Celiac ganglion
What are the organs that the celiac ganglion goes to
Stomach (inhibits periastalis)
Liver (glycogenolysis, Lower biliary tree flow)
Pancreas (decrease insulin, increase glucagon)
what is the special structure that the greater splanchic nerve goes to
Chromophin cells in adrenal (NE, Epi)
at are the levels of the lesser splanchnic
T10-11
What does the lesser splanchic go to
sup mesenteric ganglion
What does the lesser splanchnic inn (6)
cecum
asc colon
prox trnasverse
Distal duodenum
jejunum
ileum
= inhibit peristalsis/absorbsion/secretion
What lvl is the least SN
T12
