Why the spinal cord is surrounded by the backbone?

Why the spinal cord is surrounded by the backbone?

The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord.

What is the function of spine?

Your spine, or backbone, is your body’s central support structure. It connects different parts of your musculoskeletal system. Your spine helps you sit, stand, walk, twist and bend. Back injuries, spinal cord conditions and other problems can damage the spine and cause back pain.

Does backbone support the spinal cord?

The vertebrae protect and support the spinal cord. They also bear the majority of the weight put upon your spine. The body of each vertebra is the large, round portion of bone. The body of each vertebra is attached to a bony ring.

How are the bones of the 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. Ligaments and muscles help keep the …

What’s the difference between the spine and the backbone?

• Backbone provides support for body and protects the spinal cord, whereas spinal cord controls the visceral activities throughout the body.

Why are there discs in the spinal cord?

Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine. Ligaments and muscles help keep the vertebrae in the right position. There are many pathways or “tracts” in the spinal cord.

Where does the spinal cord pass through the vertebra?

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. Ligaments and muscles help keep the vertebrae in the right position.

How does the spine protect the spinal cord?

It provides a framework to support the trunk and rigid protection for the spinal cord. Portions of the spine surround the spinal cord providing bony protection for the spinal cord just as the skull protects the brain with a bony shell. The spine is made up of 24 segments called vertebrae. These bones are stacked on top of one another.

How does the spine support the trunk of the body?
