WHAT IS THE DIFFERENCE BETWEEN THE ANTERIOR and POSTERIOR ROOT OF THE SPINAL NERVES?

∙ 9y ago
The cerebrospinal nervous system consists of the brain, spinal cord and the peripheral nerves given off by these to the outer parts of the body. 31 pairs of nerves emerge from the spinal cord. Each nerve has 2 roots - 1 anterior(at the front of the spine) and 1 posterior (at the back of the spine) carrying sensory nerves. Motor nerves carry impulses to the muscles, & have the responsibility for bodily movement. On the other hand, sensory nerves are responsible for carrying sensory impulses which provide the brain with information about sensation i.e. hot and cold.
