The nervous system also plays a critical role in sensing external stimuli, processing sensory information, and responding to the environment, helping organisms survive and adapt to changes.
It sounds like you're asking about how the nervous system functions or how it can be described in paragraphs. Here’s a brief explanation in paragraph form:
The nervous system is a complex network of cells that transmit signals throughout the body. Its primary role is to control and coordinate various functions, from voluntary movements like walking to involuntary ones like breathing. The system is divided into the central nervous system (CNS), consisting of the brain and spinal cord, and the peripheral nervous system (PNS), which includes all the nerves branching out from the spinal cord to the rest of the body. Neurons, the fundamental units of the nervous system, communicate through electrical impulses and chemical signals. These impulses travel across synapses, tiny gaps between neurons, allowing messages to be relayed rapidly
