3D Models of the Sensory System and organs including the nose tongue skin ear eye smell taste touch hearing vision.

The sensory system is the set of peripheral and central structures of the nervous system responsible for the perception of signals of various modalities from the surrounding or internal environment. The sensory system consists of receptors, neural pathways and brain regions responsible for processing the received signals. The most well-known sensory systems are sight, hearing, touch, taste and smell. With the help of a sensory system, one can feel physical properties such as temperature, taste, sound or pressure.

Also sensory systems are called analyzers. Analyzers are a set of formations that perceive, transmit and analyze information from the surrounding and internal environment of the body.

Sensory systems are divided into external and internal; external ones are equipped with exteroreceptors, internal ones – with interoreceptors. Under normal conditions, the body is constantly carried out a complex effect, and the sensory systems work in constant interaction. Any psychophysiological function is polysensory.

The main principles of the design of sensor systems include:

The principle of multi-channel (duplication in order to increase the reliability of the system)
The principle of multi-level information transfer
The principle of convergence (terminal branches of one neuron are in contact with several neurons of the previous level; Sherrington funnel)
The principle of divergence (multiplication; contact with several higher level neurons)
Feedback principle (all levels of the system have both upstream and downward paths; feedbacks have a braking value as part of the signal processing process)
The principle of corticalization (in the new cortex all sensory systems are presented; therefore, the cortex is functionally multi-valued, and there is no absolute localization)
The principle of two-sided symmetry (there is a relative degree)
The principle of structural and functional correlations (the corticalization of different sensory systems has different degrees)
