The spinal cord is attached to the brain. It is how messages from the brain are sent to various locations along the nervous system.

What is the function of the CNS?
The central nervous system includes the brain and spinal cord. It controls behaviors in the body.
How do sensory neurons and motor neurons act in opposite ways?
Sensory neurons carry impulses from the sense organs to the brain and the spinal cord . Motor neurons carry impulses from the brain and spinal cord to muscles or glands.
What is the difference between spinal column and vertebral column?
because during the growth of human beings the vertebral column outgrows the spinal chord. that's why we don't find the spinal cord starting from lower lumbar region where lumbar puncture is done.
What body system includes the brain spinal cord and sensory receptors?
The peripheral nervous system, contains all the nerves in the body that lie outside of the spinal cord and brain. They also relay signals from sensory receptors that monitor external conditions to the central nervous system.
What organ protects the spinal cord?
Your vertebral column protects the spinal cord. Vertebral column is supported by strong ligaments. Most importantly the muscle tone is there, which act on vertebral column, to protect your spinal cord.
What is the function of the intervertebrae discs?
The major function of an intervertebral disc is to absorbs shock.
Shock absorbing tissue that protects the brain and the spinal cord?
The cerebral spinal fluid which bathes the brain also cushions it from shock. That is contained within three layers of meninges or protective coverings which also act to hold the brain in place to prevent it from hitting the inside of the skull during rapid acceleration or deceleration.
What are the demographics of spinal cord injuries?
10,000 new.(SCIs) occur each year in the United States. The typical patient.is a man between the ages of 19 and 26, injured in a motor vehicle accident (about 50% of all SCIs), a fall (20%), an act of violence (15%), or a sporting accident (14%).
What other parts of the body work with the brain?
The brain is part of the Central Nervous System. The central nervous system includes the brain and spinal cord. Your brain is connected with every part of your body by nerves which extend out from your spinal cord. These nerves are the pathways that receive signals, that send them to your brain, then your brain decides what to do with the received information and sends out new signals to respond to that input.
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 :)
IS spinal cord is encased in bones called vertebrae to help protect it?
yes it is encased to keep for any mishaps occurring and damaging the spinal cortex:)))
Why is spine important?
The lumbar spine supports the weight of the entire column and, therefore, withstands a great load
