Nervous System

Abstract

To adapt to new conditions, the body must constantly be in communication with its environment. Stimuli are absorbed and emitted. Movements have to be targeted and coordinated. Reflexes and essential life processes such as breathing, heart activity or digestion need to be continuously adjusted according to their demand. For all these processes internal and external stimuli are sensed via receptors, transmitted to the brain via neural pathways, processed and again redirected to the effector organs. Failure in each single part of the nervous system usually causes significant malfunction, mainly manifested by disturbed sensory perception (pain, temperature, sensitivity), paralysis, poor coordination or inability to speak properly.
