The caudal hindbrain develops into the myelencephalon which is the future home of the adult medulla oblongata. The medulla contains life-sustaining gray critical for respiration, cardiovascular control and basic brainstem ‘reflexes’. All white matter pathways to & from the spinal cord traverse the medulla,
including the pyramidal tract that provides dexterous distal limb control (fig 7.18).
