Question 34

visceral pain

Answer 34

dull poorly felt pain | referred to where sympathetic nerve is defined

Question 35

somatic pain from viscera

Answer 35

pain felt locally on body wall when the affected organ touches it

Question 36

T1-5

Answer 36

cardiopulmonary splanchnics | go to the heart

Question 37

T5-9

Answer 37

greater splanchnic nerves supply the foregut goes to celiac ganglion to synapse and post synaptic nerve goes to the foregut organs OR goes directly to the adrenal medulla

Question 38

T9-11

Answer 38

lesser splanchnic nerve supplies the midgut by synapsing with ganglion at the base of the superior mesenteric artery also travels to articorenal ganglia (junction of the aorta and the renal artery) supplies the kidneys and upper half of the ureter also travels to the adrenal medulla

Question 39

T12

Answer 39

least splanchnic nerve supplied the gonads - synapses in inferior mesenteric plexus post synaptic nerve travels down the gonadal artery to innervate the gonads

Question 40

L1-5

Answer 40

lumbar ganglion synapses in the inferior mesenteric plexus inferior mesenteric ganglion to supply the hindgut OR supply the gonads OR travel into the limbs

Question 41

sacral ganglia

Answer 41

sinapse in the inferior hypogastric plexus and supply the hindgut also travel from inferior hypogastric plexus to superior hypogastric plexus and supply the superior pelvic viscera OR go through both and synapse in the inferior mesenteric ganglion to supply the hindgut or supply sympathetic innervations of the lower limb
