SPINO OLIVARY TRACT

• Arise from cells of the nucleus proprius of the spinal cord.
• The tract terminates in the caudal olivary complex of the medulla    (medial and dorsal accessory olivary nuclei).
• This forms another pathway to the cerebellum for exteroceptive and proprioceptive afferents.
• Action potentials reach the cerebellar cortex ipsilateral to their origin within the peripheral nerves.
• This tract is important in informing the cerebellum of the position of the limbs and the external environment.
