Anatomy of the Spine
The nerves coming out
from the spinal cord
- The spine is made up of spinal cord, which starts from below the brain and goes upto the tail-bone
- The spinal cord has got nerves which arise from the spinal cord and go to various different parts fo the body
- Apart from these are the vertebrae called bones surrounding the spinal cord.There are approximate 24 mobiles vertebrae
- These are mobile because between every 2 vertebrae are structures called discs. Discs are cushion like structures, which allow movement between 2 vertebrae or bones
- Apart from these discs, there are also ligaments surrounding the bones, which help in movements of the bones over one another
- Behind the discs are nerves, which are coming out of the spinal cord, these go from the middle of the body to the arms & legs. Nerves are like wires, which transmit signals from the brain & spinal cords, to the arms & legs to aid in their movement
