6. Spasms Elsewhere
The central nervous system is what controls our movements and behavior. Of course, this is made up of the brain, the spine, and the network of nerves that run through the body and connect our limbs to the motor cortices in our brains.
This is what allows us to plan a movement and then execute it. This is why damage to the CNS by tetanus can cause us to spasms and feel unable to move normally around the face and jaw – but with time it can also travel further and affect other limbs and parts of the body. These can also start spasming and jolting out of control, giving you the feeling of being out of control of your faculties.
