Functional anatomy of organ of sense. Understanding of about analysers: their components, classification

Traditional classification of the five sense organs: sight, smell, taste, touch, and hearing. As far back as the 1760's, the famous philosopher Immanuel Kant proposed that our knowledge of the outside world depends on our modes of perception. In order to define what is "extrasensory" we need to define what is "sensory". Each of the 5 senses consists of organs with specialized cellular structures that have receptors for specific stimuli.

Analyzers (sensory organs, afferent system, sensory systems) - are a set of interacting structures of the peripheral and central nervous systems, which carry the perception and analysis of phenomena occurring in the environment and within the organism.

All analyzers are similar by their structure (receptor - nerve - brain). In modern physiology according to the anatomical unity and features there are eight kinds of analyzers: and interoceptive, which get the information from inner organs and systems. exteroceptive, which get the information from environment (visual, acoustical, tactile, painful, temperature, gustatory, rhinal (райнел
