The spinal cord is located in the spinal canal, and its upper end is connected to the medulla oblongata of the brain, and its lower end is conical in shape.
The spinal cord is located in the spinal canal and its upper end is connected to the medulla oblongata of the brain, which serves as a conduit between the brain and the body. The brain sends out signals and then transmits them to all parts of the body through the spinal cord nerves. Pairs of nerve bundles emanate from the spinal canal through the intervertebral foramina on either side, innervating the whole body and limbs, controlling sensation and muscle movement in the body and limbs.
Hot and cold pain felt in various parts of the body are transmitted through the spinal cord to the brain for expression. If the spinal cord is compressed or damaged, the limbs will show symptoms below the corresponding level of damage, such as paralysis of the limbs, numbness, and difficulty in defecation.
Therefore, the function of the spinal cord is very important to the human body and should be protected. In daily life, it is necessary to prevent cervical spondylosis, lumbar disc herniation and lumbar spinal stenosis. Serious fractures and trauma to the cervical, lumbar and thoracic spine should also be prevented to protect the function of the spinal cord.
