A SPIDER ON YOUR KNEE

A Your body first recognizes that thing as a spider

B Other interneurons pass that signal to neurons that carry it up your spinalcord to your brain

C The signal travels up an axon and into your spinal cord, where it getspassed on to several interneurons

D The connections between neurons interpret and split the signal so thatyou can either scream, and start swinging your arms wildly about the spider

or remain calm, and remove the spider

E The spider’s legs activate your sensory neurons in the skin

F Some interneurons send a signal straight down neurons to yourquadriceps muscle on your thigh, triggering you to kick your leg out beforeyou even know what’s going on
