Sensory organs include a group of organs responsible for processing of information received from the environment. Sensory system includes a system consisting of different types of sensory receptors, neuronal pathways and certain parts of human brain necessary for processing this information. Therefore, each type of sensory system (analyzer) consists of 3 main parts: peripheral, conduction and central. Peripheral part consists of the receptors presenting in the form of the nerve endings or specialized nerve cells, perceiving and partially analyzing the stimulus. Impulses of different frequencies and amplitudes occur in the receptors and are transmitted through the centripetal fibers to the appropriate parts of the cerebral cortex. Centripetal fibers form a conduction section of the analyzer. Central part of analyzer includes nervous centers of brain stem and cerebral cortex where it takes place an ultimate analysis of received information. On the basis of information received from external or internal environment the central nervous system provides reflective adaptive response. A human being perceives all the diversity of our world with the help of these analyzers.
Sensory system includes such analyzers as:
- Vision
- Hearing
- Somatic sensation
- Smell
- Taste
