Answer 28

White rami (pink)

Question 29

Contains unmyelinated axons, present at ALL 31 SPINAL CORD LEVELS Where signals leave ganglia to exit out of spinal nerves to rest of body

Answer 29

Gray Rami (red)

Nerves that are formed by signals coming off sympathetic chain in pathway to viscera below diaphragm

Answer 31

Splanhneic nerves

Question 32

What must start at T5-L2?

Answer 32

Sympatheic signals to the viscera below the diaphragm
