2 type of motor neurons
A
lower motor
upper motor
2
Q
what are the lateral pathways
A
control both proximal and distal muscles and are responsible for most voluntary movements of arms and legs
- lateral corticospinal tract
- rubrospinal tract
3
Q
what are the medial pathways
A
axial muscles and are responsible for posture, balance, and coarse control of axial and proximal muscles.
- vestibulospinal tracts (both lateral and medial)
- reticulospinal tracts (both pontine and medullary)
- tectospinal tract
- anterior corticospinal tract
