What is a severed leg?
a leg that has been cut, or 'severed', in half
What two prominent muscles have been affected if your right accessory nerve was severed in an accident and there was muscle atrophy?
When a nerve is cut, the muscle that communicates with the brain along that nerve no longer functions. this results in atrophy, the muscle thinning. It may not be repairable since the nerves degenerate when they get cut. If the surgeon says a nerve graft is doable, then there can be good sucess with a repair.
Why may a person need to have a limb amputated?
The pain or feeling is known as "Phantom Pain" and is commonly reported by amputees. It's believed to be related to our body's electrical field - under Kirlian photography, plants that have had their leaves severed still show the outline of its bioelectric field after the piece has been cut and removed. Though the mechanism isn't fully understood, the pain signals to the brain from a severed limb or other injury are known to continue well after the area has apparently healed. Some theories believe that the nerve being severed causes an overload in the electric signals to the brain, which continue to be sent by the nerve path to the brain after the limb is gone. Since the nerve pain originated in the limb, the brain signals make it seem like the pain is actually coming from the limb when in fact it's not.
Can the human brain stay active after it's been severed from the body?
Shortly. Once it has been severed from the body it can still blink and stuff which is what the bag was for when the executed people. Once the blood and oxygen has left the severed head (only like 2-3 min) all life will seize to exist.
What could cause a mysterious nerve pain on your shoulder similar in intensity to a sunburn?

Can cut flowers be replanted after they have been used in a vase?
No, cut flowers cannot be replanted after they have been used in a vase because they have been severed from their roots and will not be able to grow again.
How fast can your brain receive a message from your nerve?
The nerve is basically composed of many chemicals that maintain an electrical balance between the differing chemicals within and on outer edge of nerve membrane. A stimulus such as pressure, heat, cold, needle prick changes the electrical charge of the outer chemical, potassium I think, on the nerve membrane driving the potassium ions through the nerve membrane and into the actual interior of the nerve. When the potassium with it's +/- charge goes into the nerve membrane then it expels sodium ( I think ) out to the outer wall where the potassium is. This reciprocal process of driving similar charged ions back and forth is the actual stimulus that goes to the brain and the brain knows there has been a change. Electrically it's the same process you see when you put two "north" ends of a magnet together then they repel each other, when you put opposite polarities they attract. This is done but on a chemical, ionic scale and we have a nerve "firing" or the creation of a "message to the brain". Now the speed of that chemical process is called absolute or relative refractory period. This process is controlled chemical reaction and the "speed" it is done is also dependent on the type of nerve it is. Nerves are generally classified as a, b or c fibers and each has a differing conduction speed.
Has the circuit been cut in the electrical system?
Yes, the circuit has been interrupted in the electrical system.
What are teased nerve fibers?
Teased nerve fibers are nerve fibers that have been carefully dissected and separated for study under a microscope. This technique allows researchers to examine the individual components and structures of a nerve fiber in detail.
Can a dove survive if it's wing has been severed?
SO long as it is kept out of danger from ferals and fed. Can make good pets.
Bad nerve pain in leg after lumbar puncture is this normal?
No, a nerve may have been accidentally contacted by the LP needle.
Which cranial nerve has been damaged when your mouth droops following carotid surgery?
Marginal mandibular branch of the facial nerve.
