Answer 18

dilation

Question 19

sympathetic effect on adrenal medulla

Answer 19

increases (increase in BP)

Question 20

parasympathetic effect on adrenal medulla

Answer 20

no effect

Question 21

sympathetic to peripheral viscera route

Answer 21

ventral root –> spinal nerve –> white ramus –> paravertebral ganglion –> gray ramus –> spinal nerve –> dorsal/ventral primary ramus

Question 22

sympathetic to internal viscera

Answer 22

ventral root –> white ramus –> paravertebral ganglion –> internal visceral organs (does not complete circle around paravertebral ganglia back to spinal nerve)

Question 23

sympathetics to head

Answer 23

ventral root (T1-T4) –> spinal nerve (T1-T4) –> white ramus –> sympathetic chain –> synapse in superior cervical ganglion –> postganglionic fibers follow arteries to head

Question 24

sympathetics to thoracic viscera

Answer 24

ventral root (T1-T4) –> spinal nerve (T1-T4) –> white ramus –> sympathetic chain –> synapse in thoracic paravertebral ganglia –> postganglionic fibers are cardiac nerves –> cardiac plexus –> organs

Question 25

sympathetic to abdominal & pelvic viscera

Answer 25

ventral root (T5-L2) –> spinal nerve (T5-L2) –> white ramus –> sympathetic chain –> splanchnic nerves –> synapse in prevertebral ganglia –> postganglionic fibers follow arteries to organs

Question 26

greater thoracic splanchnics

Answer 26

preganglionic fibers for T5-T9 –> synapse at celiac ganglion

Question 27

lesser thoracic splanchnics

Answer 27

preganglionic fibers for T10-T11 –> synapse at superior mesenteric ganglion

Question 28

least thoracic splanchnic

Answer 28

preganglionic fiber for T12 –> synapse at aorticorenal ganglion

Question 29

lumbar splanchnics

Answer 29

preganglionic fibers for L1-L2 –> synapse at inferior mesenteric ganglion

Question 30

vagus nerve

Answer 30

preganglionic fiber for parasympathetic (cranial nerve X)

Question 31

pelvic splanchnics

Answer 31

preganglionic fibers for parasympathetic (S2-S4)

Question 32

all preganglionic neurotransmitters are _

Answer 32

acetylcholine

Question 33

parasympathetic postganglionic NT

Answer 33

acetylcholine –> internal visceral organs

Question 34

sympathetic postganglionic NT for sweat glands

Answer 34

Ach

Question 35

sympathetic postganglionic NT for blood vessels

Answer 35

Ach or norepinephrine

Question 36

sympathetic postganglionic NT for internal visceral organs

Answer 36

norepinephrine
