The medulla oblongata is the lowest part of the brainstem and serves as the site of connection between the brain and the spinal cord. Located just above the foramen magnum in the skull and in front of the cerebellum, the
medulla oblongata contains a number of nerve centers which are responsible for controlling involuntary processes such as the heartbeat, breathing, and body temperature regulation. It is only about 2.5 centimeters wide and comprises less than one percent of the weight of the central nervous system. In spite of its small size, though, it is integral in the transmission of nerve impulses between the spinal cord and the higher brain. Many of the nerve fibres which pass through the medulla oblongata cross over, so that many impulses from the right side of the brain control functions on the left side of the body and vice-versa.
