Nervous systems

Question

How nervous systems receive the information about external environment, the organs and the tissues?

Answer 1

Information regarding the conditions of external and internal environments, such as pressure, temperature, touch, spatial pH, position, metabolite levels, light, sounds, etc., are collected by the specific neural structures known as the sensory receptors. Sensory receptors are distributed all through the tissues as per their specific roles. The receptors acquire that particular information and transmit them through their own axons or through the dendrites of neurons which joins them. The information arrives the central nervous system which interprets and uses it in order to control and regulate the body.
