sANS Flashcards
What are the sections of the cervical sympathetic chain? give vertebral levels
superior (CV2-3)
Middle (CV6)
Inferior (CV7)
what is the stellate ganglion
merger of inferior cervical chain and T1 spinal nerve
what vertebral level innervates the heart and lungs and give the verterbal level
T1-5 via the cardiopulmonary nerves
where are the splanchnic nerves found? what are their names?
T5-12
Greater Splanchnic
Lesser Splanchnic
Least Splanchnic
vertebral levels for each splanchnic nerve
greater = T5-9
lesser = T10/11
least = T12
what do the splanchnic nerves innervate?
greater = celiac ganglion
lesser = superior mesenteric / aorticorenal ganglion
least = renal plexus and adrenal gland
Where are the splanchnic nerves in the lumbar region? which division innervates what?
L1-L4/5
L1/2 = inferior mesenteric ganglion & superior hypogastric plexus
L3/4 = intermesenteric & superior hypogastric plexus
where are the sacral splanchnic nerves? what do they innervate?
S1-S5
Inferior Hypogastric Plexus
