The pyramidal tract produces fine movements associated with skill, e.g. writing and playing a musical instrument. This tract is composed of direct connections that contain no synapses within the brain stem. Therefore the neurons pass directly through the medulla oblongata
 
*Most developed in primates, although may exist in other species such as the cat, where it aids in grooming.
