The spinal cord is a slightly flattened cylindrical shape, located in the center of the back of the human body, before and after the two longitudinal grooves are divided into two symmetrical halves, playing the role of the upper and lower.
The spinal cord is located in the center of the back within the spinal column and is cylindrical in shape, which is basically consistent with the curvature of the spinal column. The spinal cord contains conduction fibers, sensory neurons, etc., which can control body movement, complete basic reflexes, and have the role of conducting excitement, etc.
The growth rate of the spinal cord is slower than that of the spinal column, and its length is generally shorter than that of the spinal canal. The upper end of the spinal cord serves as a fixed connection to the human brain. The spinal column is not only the head of the supporter, but also the center axis of the human torso, supporting the body’s own weight, protecting the body cavity internal organs and other roles.
It is recommended to pay attention to the protection of the spine, spinal cord, to avoid prolonged maintenance of a movement, to avoid trauma.
