Quick Answer: Where Is Spinal Cord Located?

Where is the spinal cord located and what is its function?

What is the main function of spinal cord?

The brain and spinal cord are your body’s central nervous system. The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.

How far does the spinal cord go down the back?

The spinal cord, about 45 cm in length, extends from the foramen magnum, where it is continuous with the medulla oblongata, to the level of the first or second lumbar vertebra (The range is T12 to L3). Below that level, the vertebral canal is occupied by spinal nerve roots and meninges.

What are the main parts of the spinal cord?

The spinal cord is divided into five sections: the cervical, thoracic, lumbar, sacral, and coccygeal regions. The level of injury determines the extent of paralysis and/or loss of sensation. No two injuries are alike.

How long is your spinal cord?

The spinal cord is about 18 inches (45 centimeters) in length and is relatively cylindrical in shape. The cervical (neck) and lumbar (lower back) segments house the spinal cord’s two areas of enlargement. A fibrous band called the filum terminale begins at the tip of the conus medullaris and extends to the pelvis.

What part of your spine controls your legs?

The lumbosacral spinal cord and nerve supply legs, pelvis, and bowel and bladder. Sensations from the feet, legs, pelvis, and lower abdomen are transmitted through the lumbosacral nerves and spinal cord to higher segments and eventually the brain.

What is the position of spinal cord?

The spinal cord is the most important structure between the body and the brain. The spinal cord extends from the foramen magnum where it is continuous with the medulla to the level of the first or second lumbar vertebrae. It is a vital link between the brain and the body, and from the body to the brain.

Where does the spinal cord begin and where is it situated?

In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends.

Why is the spinal cord so important?

The spinal cord controls various parts of the body and plays an important role when it comes to bladder control. The spinal cord forms a vital link between the brain and the rest of the body and is part of the central nervous system. Together with the brain it controls bodily functions, including movement and behavior.

How is spinal cord protected?

The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.

What happens if the spinal cord is damaged?

Injuries to the spinal cord can cause weakness or complete loss of muscle function and loss of sensation in the body below the level of injury, loss of control of the bowels and bladder, and loss of normal sexual function.

Why does the spinal cord hurt?

Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. If you’re in poor physical condition, constant strain on your back can cause painful muscle spasms. Bulging or ruptured disks. Disks act as cushions between the bones (vertebrae) in your spine.
