Nervous and Endocrine Systems

According to biology's classical view of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory information by sending and receiving signals to and from various regions of the animal's body. In order to react to such situations, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body. Around 550 to 600 million years ago, worm-like invertebrates were the first to develop nerve tissue. Recent research on the existence and function of electrical signals in plants has, however, called into question this conventional wisdom. The existence of a plant nervous system and the need for the development of the scientific discipline known as plant neurobiology have been suggested by several researchers in light of these discoveries
