Nerve fibers in the central nervous system (brain and spinal cord) cannot fully regenerate themselves. Thus, these nerve cells are permanently damaged. Insulating a Nerve Fiber Most nerve fibers inside and outside the brain are wrapped with many layers of tissue composed of a fat (lipoprotein) called myelin.
Is the brainstem part of the spinal cord?
The brainstem is the lower part of the brain that connects with the spinal cord. It controls functions that we don’t usually think about.
