sensory nervous system. Each sensory organ contains millions of receptor cells (dendrites) that send cell signals to the brain through the process of cell signaling. in some cases signals are sent directly to the spinal cord.
Your nervous system would respond by sending an electrical message to your brain through your nervous system. Once you have recognized you were hurt, you would go and get a band-aid.
In the nervous system, electrical signals travel throughout the brain and into the body via nerves and nerve fibers. Electrical signals are how the brain tells the body what it should do.
Nerve cells can transmit electrical impulses throughout the body.
The nervous tissue
Nervous tissue is composed of neurons that use electrical signals to transfer impulses throughout the body.
it relays info through electrical signals; its signals work at the same speed as those of the nervous system.
Neurons transmit and receive signals in the nervous system
neuronal cell signals travel throughout the body through the nervous system. The signal is electrical, and the fastest type of cellular signal. The electrical impluse is generated by action potentials.
Information gets from the CNS to the tissues through neurons. These specialized cells transmit and receive signals from the brain and other parts of the nervous system.
No. Nor can direct current, for that matter. Fiber optics is designed to transmit light signals, not electrical currents.
The nervous system helps your body to sense things around it by taking in input from receptor cells, which sense things, and transmit these signals at super-fast speeds to your brain, which processes the signals. These signals are then sent back through the nervous system to muscle cells or another form of output, such as salivary glands.
Your nerves do. Your brain sends electrical signals through your nerves to your muscles to make you move. Signals from the far ends travel through nerves back to your brain, so you can see, hear, smell, taste, and feel.
The basic signal in the nervous system is called an action potential. It is a rapid change in the surface charge of the cell membrane from a value around -70mV to 30 mV over several milliseconds controlled by the selective flow of sodium Na+, calcium Ca++ and potassium K+ ions (mostly).
