●Extra-pyramidal system include
1- Tecto-spinal tracts
•Lateral tecto-spinal tract function: it's responsible for visual reactions
•ventral tecto-spinal tract function: it's responsible for auditory attack and reactions
○ So if damage occur, they will lose their corresponding function
2- Reticulo-spinal tracts:
•Lateral: crosses to the opposite side
○ if damage occur, lose its function at the opposite side
•Ventral: passes in the same side
○ if damage occur, lose its function at the same side
