Reflex Occurs over pathways called reflex arcs Reflex arc The Reflex Arc Figure 711a Stimulus at distal end of neuron Skin Spinal cord in cross section Interneuron Receptor Effector. Mr. E Murphy. Strange fact. A newborn baby's 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. 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. The nervous system works by sending electrical impulses along neurones (nerve cells).. The Nervous System. There are two main parts:. Central nervous system. – brain and spinal cord. A network of nerves. 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.
