The central nervous system consists of the brain and spinal cord. General anesthesia affects the central nervous system by shutting down the brain's pain centers so the body does not feel pain. Paralysis can originate from damage to the central nervous system, with injuries or diseases destroying brain cells that can paralyze parts of the body on one side. Paralysis may be spastic if muscles are stiff from brain damage or flaccid if spinal cord nerve cells controlling movement are damaged.

3. HyperesthesiaCentral Nervous System General anesthesia primarily affects the central nervous system. Your central nervous system consists of your brain and spinal cord. According to the University of Maryland Medical Center, general anesthesia shuts down the brain's pain centers so your body doesn't recognize pain.

4. -plegia: Suffix meaning paralysis. Hemiplegia paralysis of one side of the bodyQuadriplegia which is paralysis of all four extremities. Paralysis of central nervous system origin can be extensive. The central nervous system consists of the brain and the spinal cord. An injury or disease that destroys brain cells may paralyze arm, leg, and face muscles, often on only one side of the body. Such brain damage generally produces spastic paralysis, in which the muscles are more stiff than normal, and reflexes are overactive. If motor nerve cells (nerve cells that affect movement) in the spinal cord are damaged directly, then the muscles become limp, and reflexes are lost. This is called flaccid paralysis.
