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 protects the delicate spinal cord?
The spinal column — also known as the spine or backbone — protects the delicate nerve tissue of the spinal cord.
What part of the body protects 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.
What is the spine protected by?
A column of bones called vertebrae make up the spine (spinal column). The vertebrae protect the spinal cord, a long, fragile structure contained in the spinal canal, which runs through the center of the spine.
Which delicate organ is protected by the vertebral column?
The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles.
How delicate is the spinal cord?
The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine. The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body.
Is spinal cord injury a disability?
Anyone with a spinal cord injury can file a claim for Social Security disability benefits as long as the injury has lasted at least three months and is expected to make it impossible for you to work for at least 12 months.
Why is it important that our spinal cord is protected?
The vertebral column is made up of separate vertebrae that are interconnected and, in the most part, moveable. This allows us to perform tasks such as bending and turning while the spinal cord remains protected.
How does damage to the spinal cord and nerves affect the other parts of the body?
Complete: A complete injury causes total paralysis (loss of function) below the level of the injury. It affects both sides of the body. A complete injury may cause paralysis of all four limbs (quadriplegia) or the lower half of the body (paraplegia).
What organ is protected by the spinal column or backbone?
The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
What are the 5 areas of the spine?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
How many vertebrae do humans have in their spine?
The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.
What organs or system does the skeletal system most interact with?
Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs. Your circulatory system delivers oxygen-rich blood to your bones.
