PRE GANG
white rami communicantes (neurones from interomediolateral nucleus and enters ganglia of sympathetic trunk), interganglionic branches,

POST GANG
grey rami communicantes (emerge from all ganglia of sympathetic trunk and innervate smooth muscle in the skin), visceral branches , splanchnic nerves (that travel to organs)

10-11 ganglia

Question 6

The abdominal ganglia is made of

Answer 6

lumbar (4-5 ganglia) and sacral (4-5) region

Question 7

The postganglionic fibres of the thoracic ganglia are

Answer 7

greater splachnic nerve - terminate at coeliac plex

less splanchnic nerve - termin @ coeliac plex and renal and adrenal plex

least splanchnic nerve - termin @ renal and adrenal plex

Answer 8

grey rami communicates, lumbar splanchnic - term @ abdominal aortic plex

sacral splanchnic nerves -term at inferior hypogastric plexus
