Which division has a single preganglionic neurons with many axon collaterals that forms 20 or more synapses with postganglionic neurons? a. sympathetic motor division
b. parasympathetic motor division
c. sympathetic sensory division
d. parasympathetic sensory division

i believe its c

Explanation:

A single sympathetic preganglionic fiber has many axon collaterals and may synapse with 20 or more postganglionic neurons.

The postganglionic axons typically terminate in several visceral effectors and therefore the effects of sympathetic stimulation are more widespread than the effects of parasympathetic stimulation.

i took a test for bio that had this question and these were the correct answers, not sure if this is any now lol

the nervous system and the muscular system work together.  

sweat reaches the surface of the skin and evaporates into the air.

muscles underneath the skin relax, causing hair on the skin to lay flat.
