NERVOUS TISSUE
SPECIAL TISSUE

The nervous tissue is the system of specialized
cells which can percept irritation from various
physical and chemical agents from external or
internal environment and transmit the resulting
excitement to functional organs
The nervous tissue realizes the interconnection
and regulation activity of tissues, organs and

That is why the nervous tissue constitutes the
structure organs of nervous system and play
integrated role in all types of functional system
in human body
