What carry electrical in your body?
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.
How long are some of the nerves that carry electrical signals to and from the brain?
up to one ft long
Cranial nerves is classified as mixed nerve?
Spinal nerves are called mixed nerves because they all carry motor, sensory, and autonomic signals between the spinal cord and the body.
Neurons that carry impulses away from the central nervous system?
Nerves that only carry impulses away from the central nervous system (CNS) are called:Motor Nerves
What nerves carry signals to and from the eyes and ears?
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
Nerves that carry impulses toward the Central Nervous system only are?
Sensory neurons are nerves that carry electrical signals only toward the Central Nervous System. These nerves are found in the ganglia.
What percentage of the nervous system perceives pain?
100%, I believe. The entire nervous system is made up of nerves. And nerves, in general receive pain, pleasure, or both. Hope this helped a little. The above is incorrect. Not all nerves carry pain signals. There are different nerves that carry information to the brain called afferent nerves and nerves that carry information from the brain out to the body called efferent nerves. There are also central and peripheral nerve fibers. The peripheral afferent nerves carry pain signals to the central afferent nerves which in turn carry the pain signals to the brain. The peripheral nervous system is made of three types of nerve fibers named groups A,B, and C type fibers. The group C fibers carry pain signals. I am trying to find the percentage myself but I have read that it is around 30% of the nervous system is capable of sensing pain.

What important is done by the nerves?
carry messages to the brain
Why are nerves myelinated?
Some neurons are myelinated so they can carry signals faster.
What important work is done by nerves?
carry messages to the brain
What is the function of the nerves in the nervous system?
The nervous system coordinates all body processes. The nerves carry electrochemical signals that transmit messages from one part of the body to another.
What is an efferent neuron?
A motor neuron is an efferent neuron as it 'sends out' a signal as opposed to sensory nerves which are afferent and relay information from the periphery towards the central nervous system.
What are cells that are modified to transmit signals from one place to another?
Neurons are the cells that carry signals from one neuron to another neuron, a muscle, or a gland.
What carries all the important nerves to the different parts of the body?
the bones carry them
What are the functions of afferent and efferent nerves?
Afferent nerves carry sensory information from the body to the brain, allowing us to sense touch, temperature, pain, and other stimuli. Efferent nerves, on the other hand, transmit signals from the brain to the muscles and glands, enabling movement and physical responses.
