Sensory Input

Question 1

Sensory Input:

Answer 1

Sensory neurons detect changes (stimuli) in the environment (inside or outside the body).
They send this information to the CNS (brain or spinal cord).

Question 2

Integration

Answer 2

The CNS processes the sensory information and decides what to do (interprets the stimulus and plans a response).

Question 3

Motor Output

Answer 3

Motor neurons carry the commands from the CNS to the muscles or glands to perform the response (e.g., moving a hand away from something hot).
