Nervous signals
In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago. In vertebrates it consists of two main parts, the central nervous sys… WebAug 14, 2024 · Sending Signals: The Nervous System. The nervous system is the major system of communication within the body. Our thoughts, emotions, and actions are all left up to the signalling done by this system. In tandem with the endocrine system, the nervous system helps regulate and control internal conditions to maintain homeostasis.
