Lateral column
What is the function of the anterior corticospinal tract?
Gross and postural motor
Where does the anterior corticospinal tract originate?
Motor and premotor cortex
Where does the anterior corticospinal tract end?
Ventral horn cells
Where can I find the anterior corticospinal tract?
Ventral column
Function of vestibulospinal tract?
Postural reflexes (automatic movements to resist gravity)
Where does the vestibulospinal tract originate?
Lateral and medial vesitibular nuclei.
Where does the vestibulospinal tract end?
