The spinal cord is a column of millions of nerve fibers that run through your spinal canal. It extends from the brain to the area between the end of your first lumbar vertebra and top of your second lumbar vertebra.
What runs down through your spine?
Running through the center of the spinal column is the spinal cord, a bundle of nerve cells and fibers that transmit electrical signals back and forth between the brain and the rest of the body via 31 pairs of nerve bundles that branch off the spinal cord and exit the column between the vertebrae.
What runs through the Centre of the vertebral column?
The vertebral arch (green) forms the spinal canal (blue) through which the spinal cord runs. Seven bony processes arise from the vertebral arch to form the facet joints and processes for muscle attachment.
What is the strongest part of the spine?
Lumbar Spine: In your low back, you have 5 vertebrae that are labeled L1 to L5 (the ‘L’ means lumbar). Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight.
What can we learn from the anatomy of the spinal cord?
Carrying signals from the brain: The spinal cord receives signals from the brain that control movement and autonomic functions. Carrying information to the brain: The spinal cord nerves also transmit messages to the brain from the body, such as sensations of touch, pressure, and pain.
Which part of the spine is responsible for linking the vertebrae together?
The facet joints link the vertebrae together and give them the flexibility to move against each other. Each vertebra has a hole in the center, so when they stack on top of each other they form a hollow tube that holds and protects the entire spinal cord and its nerve roots.
What is the difference between vertebral column and spinal cord?
The vertebral column surrounds the spinal cord which travels within the spinal canal, formed from a central hole within each vertebra. The spinal cord is part of the central nervous system that supplies nerves and receives information from the peripheral nervous system within the body.
