- The spinal cord is an important part of the central nervous system. It extends from neck to waist.
- Its main function is to send information from the brain to the body and from to the body to the brain.
- It controls reflex actions like salivation, knee jerk, blinking of eyes.
- The spinal cord is connected to the periphery through 31 pairs of spinal nerves.
- Each spinal nerve is joined to the spinal cord through two routes: the dorsal and ventral routes.
- If dorsal routes are injured, we will not have sensations while if ventral routes are injured, we will not be able to move our body and control reflex actions.
