Organs and parts of your body send information to the central nervous system (that's your brain and spinal cord) by electrical impulses. When the impulses reach the central nervous system, a response is triggered.
For example, if you touch a hot object, receptors on your skin will trigger an action potential in nerve cells. This action potential will be passed on to the next cell and so on until it reaches the central nervous system. The triggering of action potentials is what causes the electrical impulse. The central nervous system will then send impulses back to your hand via a motor nerve and will cause you to automatically pull your hand away.
Nervous system is a system present in the body of almost all living organisms.it consists of the brain,the spinal cord and network of neves in humans.the main function of nervous system is to conduct,transport and react to the various messages,impulses and various biological processes are dependent on this system directly or indirectly.
The system that carries messages in your body, is the Nervous system.
The peripheral nervous system carries impulses between the spinal cord and other body parts.
rthe nerves
It is what carries the nerve impulses between your body and the brain.
autonomic nervous system
Nervous tissue, specifically neurons, carry messages from the brain and spinal cord to other parts of the body. These neurons transmit signals in the form of electrical impulses to communicate sensory information and motor commands.
brain or spinal cord
Peripheral nervous system:
Efferent neurons carry impulses from your brain and spinal cord to other nerves, glands, and muscles in your body. the central nervous system
dendrtes
The sensory nervous system. This brings information into the cord and to the brain.
