If the myelin sheath is able to repair and regenerate itself, normal nerve function may return. However, if the sheath is severely damaged, the underlying nerve fiber can die.
Because nerve fibers in the central nervous system (brain and spinal cord) rarely regenerate, such damage is irreversible.
What else can I help you with?
Are spinal nerves able to repair themselves after being damaged?
no
Is spinal nerves are able to repair themselves after being damaged?
No, otherwise you would see para and quadriplegics getting better.
Why is paralysis permanent?
Paralysis can be permanent due to damage to the nerves or spinal cord, which disrupts the communication between the brain and muscles. Injuries or conditions that result in the loss of nerve function can lead to permanent paralysis because the nerves are unable to regenerate or repair themselves fully. In some cases, the extent of the damage may be severe enough to prevent any recovery of movement in the affected areas.
Which parts of the frog's nervous system can be observed in its abdominal cavity and hind legs?
In the abdominal cavity you should be able to observe vague nerves which carry nerve impulses to the liver, heart, lungs, pancreas, intestine, and stomach. Sympathetic ganglia may also be observed. In the hind legs you should be able to observe the sciatic nerve.
What will happen if the spinal cord is cut or damaged in the neck?
We wont be able to walk properly and as the nerves are joined to the spinal cord the immediate action messages will take time to reach the brain and then there will be a problem in the proper functioning of the reflex action
After injuri spainalcord you are not able to stand and waclk?
The spinal cord contains the nerves that transmit communications from the brain to the rest of the body. If the spinal cord is injured there may be partial or complete paralysis of the legs depending on where the damage occurred along the vertebrae.
What is spinalcord?
The spinal cord is the major bone structure of the body. It holds the body in an upright position. The spinal cord protects series of "wires" or "cords" that connect the brain to the body, so that the brain would be able to send messages to the different parts of the body for it to move or to react. The Spinal Cord is vital to our body, because the spinal cord (as stated earlier) contain nerves, veins, etc. that is connected to the brain, thus becoming an essential part of the nervous system. If the spinal cord (which protects the nerves) is damaged, then serious medical illness can occur.
Why does your spine need water?
The spine needs water to be able to lubricate the joints between the vertebrae. When the spinal column gets low on moisture, the nerves within the canal can get pinched between the vertebrae.
Why are most spinal cord or nerve tissue injuries permanent?
Nerve tissue mass and spinal fluid are unable to replicate. Spinal cord injury is damage to the spinal cord that causes loss of sensation (feeling) and motor (muscular) control. There are approximately 250,000 people in the USA who currently have spinal cord injuries and a further 10,000 accidents to the spinal cord occur each year! An injury to the Spinal cord can happen to anyone at any time of life. The typical patient, however, is a man between the ages of nineteen and twenty-six. The most common causes of a Spinal Cord Injury are motor vehicle accidents (which are responsible for 50 percent of all cases), a fall (20 percent), an act of violence (15 percent), or a sporting accident (14 percent). Alcohol or drug abuse is involved in many of the accidents that result in spinal cord injuries. About 6 percent of those who suffer injury to the lower spine die within a year while approximately 40 percent of those who suffer injury to the upper spine die within a year. The spinal cord is a long rope-like piece of nervous tissue. It runs from the brain down the back. It is contained within the spinal column. The spinal column consists of a set of bones known as vertebrae. Pairs of nerves travel from the spinal cord to muscles in the arms, legs, and other parts of the body. Messages travel from muscles to the spinal cord and then to the brain along one set of nerves. Messages travel in the opposite direction, from brain to spine to muscles, along the other set of nerves. Each pair of nerves is connected to the spinal cord in the space between two adjacent vertebrae. The nerves are named for the vertebrae where they enter the spinal cord. The five sets of nerves connecting to the spinal cord are defined as follows: * C1-8 nerves enter the spine near the eighth cervical vertebrae, located in the neck. * T1-12 nerves enter the spine near the thoracic vertebrae, located in the chest. * L1-5 nerves enter the spine near the lumbar vertebrae, in the lower back. * S1-5 nerves enter the spine through the sacral vertebrae, located in the pelvis region. * The coccygeal nerves (pronounced kock-SIHJ-ee-uhl) enter the spine through the coccyx, or tailbone. Injury to the spinal cord may damage any one or more of these nerves. When nerves are damaged, messages can not travel from the brain to the body's muscles, or from the muscles to the brain. For example, a person may lose their sense of touch if nerve messages are not able to travel from the fingers to the brain. Or a person may lose the ability to walk if nerve messages can not travel from the brain to leg and foot muscles. Other functions, such as urination, sexual function, sweating, and blood pressure, may also be affected. Further information is on the link provided :)
How can fat cells be able to help people with spinal cord injuries?
Studies show that fat cells can be changed into nerve cells (by obtaining stem cells from a patient's own fat), thereby possibly helping repair spinal cord injuries.
Why do you have nerves?
You have nerves so that you are able to move. If you didn't have any nerves you would be a very still person.
