Brainstem- The brainstem is the region at the base of the brain that is located between the cervical spinal cord and the deep cerebral hemispheres. It plays a crucial role in controlling some involuntary bodily functions like breathing and heartbeat.
Spinal cord- A column of nerve fibers that extends from the skull base to the middle of the back. It has three thin membrane-like layers of protecting tissue covering it. The vertebrae encircle the spinal cord and its surrounding membranes (back bones).
