• proccess info
• uses info to cundoct behavior

Question 2

the central nervous system

Answer 2

interagated and transforms information

Question 3

basic model of the nervous system

Answer 3

what is the stimulus?

what sensory receptors are activated

what is the transformation where in the nervous system does it occur

what effectors produce the response

what is the response
