In order to understand behavior, we must understand the operating mechanism of the nervous system. What is the function of the nervous system?. A. Bacterial Infections of the Nervous System. 1. Bacterial Meningitis. A) Although bacteria can infect the brain, spinal cord, and peripheral nerves, they more commonly infect the meninges and cerebrospinal fluids resulting in meningitis. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System. And this is your brain – IN ANATOMY!!. Or better yet…. The Nervous System.

Once the teacher gives the signal, the start person will pass the object to their right. 1. Two main divisions. a. . Central Nervous System . (CNS) – consists of brain and spinal cord. b. .
