Nervous system signals travel through electric impulses from "summary" of Physics of the Human Body by Richard P. McCall
The nervous system is a complex network of cells that transmits signals throughout the body. These signals are essential for controlling various bodily functions, including movement, sensation, and thought. One key aspect of how the nervous system functions is through the transmission of electric impulses. When a signal is sent from one part of the body to another, it travels through specialized cells called neurons. Neurons are capable of generating electrical impulses, which allow them to communicate with each other and with other cells in the body. This process is crucial for the proper functioning of the nervous system. The transmission of signals through electric impulses is a rapid and efficient way for the body to communicate with itself. These impulses can travel at speeds of up to 100 meters per second, allowing for quick responses to stimuli. This rapid communication is essential for tasks such as reflex actions, where the body needs to respond quickly to a potentially harmful stimulus. The generation of electric impulses in neurons is a complex process that involves the movement of charged particles across the cell membrane. When a neuron is stimulated, it allows ions to flow in and out of the cell, creating a difference in electrical charge across the membrane. This difference in charge is what generates an electric impulse.- The transmission of nervous system signals through electric impulses is a fundamental aspect of how the body functions. It allows for rapid communication between different parts of the body and is essential for controlling various bodily functions. By understanding how electric impulses work in the nervous system, we can gain insight into the intricate workings of the human body.
