PPT-The Nervous System Part I:

Organization Spinal Cord and Peripheral Nerves Introduction Most of the rapid changes in a vertebrates internal or external environments are mediated by the nervous system Activation of the correct combination of effectors so that the appropriate responses are made requires a processing of signals within the nervous system that is called coordination or integration. 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. Functions of the Nervous System. Sensory input – gathering information. To monitor changes occurring inside and outside the body. Changes = stimuli. Integration. To process and interpret sensory input and decide if action is needed. Central. Nervous. System. (CNS). Peripheral. Nervous. System. (PNS). 2. ". You have brains in your head..

The nervous system has 2 major components:. Central Nervous System (CNS). Peripheral Nervous System (PNS).. The CNS. The Central Nervous System includes the brain and the spinal cord. . They are so important to the human body that they are encased in bone for protection.. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System.

Once the teacher gives the signal, the start person will pass the object to their right. Vocabulary. Afferent. Autonomic Nervous System. Cerebral Spinal Fluid. Conductivity. Congenital. Efferent.
