Compare the characteristics of direct and indirect motor
pathways.
Expert Solution
Step 1
Two vestibulospinal pathways; medial and lateral. They originate from the vestibular nuclei, which obtain input from the organs of equilibrium.
Step 2
The elements of motor pathways are the rubrospinal tract, the vestibulospinal tract, the tectospinal tract, and the reticulospinal tract. The task of lower motor neurons can be allocated into two distinct groups: the lateral corticospinal tract and the anterior corticalspinal tract.
