The spinal cord is a cylindrical collection of nerve fibres and other tissue that connects all parts of the body to the brain.
The spinal cord is split into several distinct sections:
- The seven cervical vertebrae support the head and have the greatest range of motion,
- The 12 thoracic vertebrae protect the heart and lungs along with the connecting rib cage.
- The five lumbar vertebrae bear most of the weight of the body and are larger. They are designed to absorb the stress of lifting and carrying heavy things. This is a common place for injuries to occur, especially with today’s more sedentary lifestyles.
- Nine bones are present at the sacrum and coccyx which attach the spinal cord to the pelvic region.
- The meninges have different functions. The first is to protect the spinal cord and the second is to provide important nutrients. Spinal cord is protected by vertebrae of vertebral column. A fluid called Cerebra Spinal Fluid flows from brain to spinal cord and back to brain.
