A
Yes- in rare circumstances
2
Q

A
Corticospinal
Rubrospinal
Vestibulospinal
Reticulospinal
3
Q
What is the reticulospinal system known for
A
Maintaining posture and muscle tone of proximal muscles
4
Q
What is the job of the vestibulospinal system?
A
Sense of balance and antigravity muscles
5
Q
What is the rubrospinal system responsible for?
A
finer muscle control of distal limbs, most important system for gait
6
Q
What is the corticospinal system responsible for?
A
motor cortex/pyramidal tract, fine motor control, most important for primates
