Sensory systems structure and role

Nature "gave" the human ability to perceive diverse stimuli environment and internal environment: the smells, sounds, colors, light, temperature, etc. Because of this, you can feel and perceive the events that occur in the environment or in your own body, and to respond appropriately to them. Getting information from the external and internal environment and its analysis takes place in the human body through the analyzers (the term suggested in 1909 by the Russian physiologist Ivan Pavlov), or sensory systems (from the Latin. “perception”).

Sensory system (analyzer) is a set of structures that receive, transmit and analyze information from the environment and internal environment of the body.

Each sensory system consists of three main parts: the peripheral (receptors), conducting (sensory nerve fibers) and central (brain stem centers and certain detection area of the cerebral cortex).
