Medulla oblongata

The last part of the vertebrate brain, continuous posteriorly with the spinal cord.


The cone of the nervous tissue continuous above the pons and below the spinal cord. Concerned with involuntary vital actions such as breathing. Many depressant drugs have secondary effects.


A continuation of the spinal cord going through the foramen magnum into the brain.


Lowest part of the brain stem, an extension in the skull of the upper end of the spinal cord; it is the most vital part of the brain, containing centers controlling respiration, heart and blood vessel function, and other activities as well as pathways for impulses entering and leaving the skull. Injury to the medulla oblongata is often fatal.


Section of the brain stem that is continuous with the spinal cord.


The lower portion of the brain stem just above the spinal cord. The medulla oblongata contains nerve centers that control breathing, heart rate, and blood pressure.


The extension within the skull of the upper end of the spinal cord, forming the lowest part of the ‘brainstem. Besides forming the major pathway for nerve impulses entering and leaving the skull, the medulla contains centers that are responsible for the regulation of the heart and blood vessels, respiration, salivation, and swallowing. Cranial nerves VI-XII leave the brain in this region.


The hindmost part of the brain, continuing into the spinal cord. In it are situated several of the nerve centres which are most essential to life, such as those governing breathing, the action of the heart and swallowing.


The lowest part of the brainstem, continuous with the spinal cord above the level of the foramen magnum of the occipital bone. It regulates heart rate, breathing, blood pressure, and other reflexes, such as coughing, sneezing, swallowing, and vomiting.


The lowermost segment of the brainstem, positioned adjacent to the spinal cord, known as the medulla. Within this region, significant centers responsible for regulating cardiac and respiratory functions are located.


Often referred to as the medulla, the medulla oblongata is the lowest section of the brainstem, situated at the skull’s base. It links the brain with the spinal cord.
