What is nervous system?
- According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals to and from various regions of the body.
- The nervous system notices bodily-impacting environmental changes, and then collaborates with the endocrine system to react to such occurrences.
- Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue.
- The discovery of electrical signals in plants and their utilization in recent decades, however, has called into question this conventional wisdom.
- These findings have led some researchers to suggest that plants have neural systems and that the science of plant neurobiology should be established.
