*Produces fine movements associated with skill, e.g. writing and playing a musical instrument.

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.

*Nerve fibres of the pyramidal system originate in the cerebral cortex and then pass to the [[Forebrain - Anatomy & Physiology#Thalamus|thalamus]], and [[Hindbrain - Anatomy & Physiology#Medulla Oblongata|medulla oblongata]].
