This is an anatomy question.

I need to explain the neural pathway that is involved when youwalk outside into the bright light and your pupils constrict, yousquint, and you raise your arm to shade your eyes.

this is an anatomy question

You walk out of a dark movie theater into bright sunlight. Yourpupils constrict, you squint your eyes and raise your arm to shieldyour face.

what are the neural pathways taken to do each thing? (pupilsconstrict, squint, move arm)

where do these signals go in the brain? where are the neuronssynapsing?
