Is paralysis in the lower body part incurable?
There are two types of spinal cord injuries. Complete spinal cord injuries refer to the types of injuries that result in complete loss of function below the level of the injury, while incomplete spinal cord injuries are those that result in some sensation and feeling below the point of injury. The level and degree of function in incomplete injuries is highly individual, and is dependent upon the way in which the spinal cord has been damaged.http://www.brainandspinalcord.org/spinal-cord-injuries/index.htmlThe prognosis of a particular spinal cord injury varies depending upon where along the spinal column the spinal cord has been injured, the severity of the injury, and which nerve fibers are damaged. As a general rule of thumb, some recovery can be expected within the first six months following injury. After six months, additional recovery is unlikelyhttp://www.brainandspinalcord.org/spinal-cord-injury/index.html A combination of physical therapy, electronic aides, medications, and surgeries can be used to help SCI survivors regain as much function as possible after injury.
What are the six main divisions of the system?
The six main divisions of the system include the spinal cord,the medulla,the pons,the midbrain,the diencephalon and the cerebral hemispheres.
What does right paracentral disc protrusion at T6-7 with moderate effacement of right anterolateral aspect of thecal sac mean?
You have protrusion of the disc between thoracic six and seventh vertebrae. This protrusion has created indentation on the sac of dura matter on the anterolateral region of the spinal cord. This can compress your spinal cord.
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 :)
What part of the nervous system is not working when people are paralyzed?
The part of the nervous system that is not working when people are paralyzed is the nerves in the spinal canal. The amount of paralysis or the limbs affected depend on where the damage is in the spinal canal.
What are the kinds of paralysis of the nervous system?
There are two types of spinal cord injuries. Complete spinal cord injuries refer to the types of injuries that result in complete loss of function below the level of the injury, while incomplete spinal cord injuries are those that result in some sensation and feeling below the point of injury. The level and degree of function in incomplete injuries is highly individual, and is dependent upon the way in which the spinal cord has been damaged. Complete spinal cord injuries result in complete paraplegia or complete tetraplegia. Complete paraplegia is described as permanent loss of motor and nerve function at T1 level or below, resulting in loss of sensation and movement in the legs, bowel, bladder, and sexual region. Arms and hands retain normal function. Some people with complete paraplegia have partial trunk movement, allowing them to stand or walk short distances with assistive equipment. In the majority of cases, complete paraplegics choose to get around via a self-propelled wheelchair. Complete tetraplegia is characterized by the loss of hand and arm movement as well. Some tetraplegics require ventilator systems in order to breathe. Depending upon the location of the injury, some tetraplegics may have some arm and hand movement present. Incomplete spinal cord injuries are more common than complete injuries, and are characterized by some degree of sensation and movement below the point of injury. The extent of an incomplete injury is generally determined after spinal shock has subsided, approximately six or eight weeks post injury. Incomplete spinal injuries can result in some feeling but little or no movement, or in some movement but little or no feeling. Incomplete spinal injuries fall under five different classifications: * Anterior cord syndrome: characterized by damage to the front of the spinal cord, resulting in impaired temperature, touch, and pain sensations below the point of injury. Some movement can later be recovered. * Central cord syndrome: characterized by damage in the center of the spinal cord that results in loss of function in the arms but some leg movement. Some recovery is possible. * Posterior cord syndrome: characterized by damage to the back of the spinal cord, resulting in good muscle power, pain, and temperature sensation, but poor coordination. * Brown-Sequard syndrome: characterized by damage to one side of the spinal cord, resulting in impaired loss of movement but preserved sensation on one side of the body, and preserved movement and loss of sensation on the other side of the body. * Cauda equina lesion: characterized by injury to the nerves located between the first and second lumbar region of the spine, resulting in partial or complete loss of sensation. In some cases, nerves regrow and function is recovered.
How do you get paralyzed?
Spinal cord injuries are caused when delicate spinal cord tissue is bruised, torn, or crushed. Spinal cord injuries can be caused by accidents, but can also be caused by diseases or disorders. As many as 400,000 Americans are living with spinal cord injuries. Most spinal cord injuries occur between the ages of 16 and 30, and about 82 percent of those who experience spinal cord injuries are male. Motor vehicle accidents account for approximately 44 percent of all spinal cord injuries. Other common causes include: • Acts of violence, including those that cause knife and gunshot wounds• Slips and falls• Sports-related injuries, mostly diving accidents• Trampoline accidents Results of Spinal Cord InjuryAfter the spinal cord has been injured, messages no longer flow through the damaged area, essentially cutting off information between the brain and certain parts of the body. Generally, the functions of the body located above the point of injury will continue to work with no loss of function, while the areas of the body located below the point of injury will be impaired. Impairment can include the following: • Motor deficit• Sensory deficit• Breathing difficulty• Bowel and/or bladder dysfunction Level of InjuryDoctors and specialists use the level of injury to most accurately predict which parts of the body are most likely to be affected by loss of movement and sensation. Complete injuries will result in total loss of movement and sensation below the point of injury, while incomplete injuries will result in some degree of loss of movement and sensation below the point of injury. Levels of injury are classified as: • Neck• C-1 to C-4• C-5• C-6• C-7 and T-1• T-1 to T-8• T-9 to T-12 Prognosis of Spinal Cord Injury The prognosis of a particular spinal cord injury varies depending upon where along the spinal column the spinal cord has been injured, the severity of the injury, and which nerve fibers are damaged. As a general rule of thumb, some recovery can be expected within the first six months following injury. After six months, additional recovery is unlikely.
What is the most number of outlets on a multi outlet extension cord?
The most number of outlets on a multi outlet extension cord are six. Any more then six outlets on an outlet extension cord and it would become dangerous.
Name six systems in the nervous system?
I think there are only two. The Central Nervous System and the Peripheral Nervous System. The CNS consists of the brain and spinal cord. The PNS everything else outside of that. The PNS includes motor, sensory, and interneurons.

What bones that protects your spinal cord are called?
They are called the vertebrae, and are divided into six different classes depending upon which part of the spine they consist of. The topmost ones are the cervical vertebrae, and the bottom-most ones the coxxygial vertebrae. The largest category are the lumbar vertebrae, which makes up at least a third of the spine as a whole.
