Opiates

Opiates Act on Many Places in the Brain and Nervous System

The limbic system controls emotions. Opiates change the limbic system to produce increased feelings of pleasure, relaxation and contentment. (red)

The brainstem controls things your body does automatically, like breathing or coughing. Opiates can act on the brainstem to stop coughing or slow breathing. (blue)

The spinal cord transmits pain signals from the body. By acting here, opiates block pain messages and allow people to bear even serious injuries. (yellow)
