∙ 12y agoThere are 12 thoracic nerves in the spine, which connect to the peripheral nerves of the midsection of the body (not the organs).
The top nerve, T1, connects to the skin and muscles of the upper back.
The next five, T2 to T6 (upper thoracic nerves), connect to the intercostal chest muscles and the skin of the chest and lower back.
The next five, T7 to T11 (lower thoracic nerves), connect to the abdominal muscles and lower back.
The bottom nerve, T12, connects to the first lumbar nerve, thereby to the buttocks and gluteus muscles.

What pairs of spinal nerves arise from the cord of these 31 pairs are cervical nerves how many pairs are thoracic nerves how many pairs are lumbar nerves and how many are sacral nerves?
31 pairs. And they arise from the combination of the ventral and dorsal roots.
How many pairs of spinal nerves extend from the spinal cord and are distributed to the muscles and skin of the trunk and limbs?

How many pairs of spinal cord nerves connect the brain to the peripheral nervous system?

How many cervical nerves are there in the spinal cord?
1 pair because there are 31 pairs of spinal nerves;8 pairs for ceveral,12 pairs for thoracic,5 for lumbar,5 for sacral.so the total is:31one (1) pair

What causes disabilities and why?
There are many, many, many different factors that can cause disabilities. For instance, if your spinal cord was damaged, you may be paralyzed from the waist down or head down, depending on where you were hit on the spinal cord. Your spinal cord sends messages to your nerves in your body, and thus cannot if broken.

How many nerve endings in the entire body?
There are approximately seven trillion nerves in the human body. There are twelve pairs of cranial nerves and thirty two pairs of spinal nerve roots which then branch out to the rest of the body.
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 :)
Where does the spinal cord start and ends?
In an adult the lower end of the spinal cord usually ends at approximately the first lumbar vertebra, where it divides into many individual nerve roots (L1). That is the reason Lumbar Puncture usually perform at L3-L4 in order to prevent accidentally injure to the spinal cord. The point where the spinal cord ends is referred to as the "conus medullaris"
How many spinal nerves are there and how are they divided?
31 pairs of spinal nerves, separated by vertebrae (exit in intervertebral foramina) of the different sections of the spine: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal.
