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. 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. Functions of the Nervous System. Functions of the Nervous System. Sensory input. Information gathered by sensory receptors about internal and external changes . Integration. Interpretation of sensory input. Motor output. Activation of effector organs (muscles and glands) produces a response. Peripheral Nervous System. Autonomic Nervous System. Allied Health I. Central Nervous System. Communication and coordination system of the body. Seat of intellect and reasoning. Consists of the brain, spinal cord, and nerves. Broca’s. area. Wernicke’s area.
