A
A - Axial
B - Proximal
2
Q
Dorsolateral spinal nuclei innervate […] limb muscles.
A
Distal
3
Q
What does the medial pathway control?
A
Axial and Proximal muscles
4
Q
What are the three major components of the medial pathway? [3]
A
- Vestibulospinal tracts
- Reticulospinal tracts
- Tectospinal or colliculospinal tract
5
Q
What is the role of the Vestibulospinal tract?
A
Carry information for the reflex control of balance and posture
6
Q
What is the role of the Reticulospinal tract?
A
Integrate vestibular and cortical inputs
7
Q
What is the role of the Tectospinal or Colliculospinal tract?
A
Important in coordinating head and eye movements
