Answer 17

Chain or collateral Motor Ganglia

Question 18

Where does sympathetic motor information enter chain ganglia?

Answer 18

white ramus communicantes

Question 19

Where does sympathetic motor information that exit chain ganglia?

Answer 19

gray ramus

Question 20

What is the difference between chain ganglia between T1-L2 and those above and below?

Answer 20

no info. entering above and below so no white ramus
