PPT-C34: The Nervous System and Neurons

Mr E Murphy Strange fact A newborn babys brain grows almost 3 times during the course of its first year Objectives Identify the importance of the nervous system in humans Know the difference between the CNS and the PNS. 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.. You have feet in your shoes.. You can steer . yourself. Any direction you choose.”. . Watch video:. Structure and Function. 2. Input. (sensation). Output. (action). In order to understand behavior, we must understand the operating mechanism of the nervous system. What is the function of the nervous system?.
