Central Control Of Movement Flashcards
Cortex of the brain is responsible for
Planning
Mid-brain is responsible for
Equilibrium
Brainstem is responsible for
Posture
Spinal cord is responsible for
Execution
Name the 2 major groups of descending pathways
1) Lateral Pathways
2) Ventromedial Pathways
What are the lateral pathways (descending) involved in
Voluntary movement of distal muscles
What are the ventromedial pathways (descending) involved in
Control of posture and locomotion
What type of pathway is the corticospinal tract?
Lateral
T or F: the Corticospinal tract isn’t heavily myelinated
False; it is heavily myelinated
List the structures traveled through in the corticospinal tract
1) motor nerve cells
2) upper motor neuron
3) midbrain
4) pons
5) medulla
6) spinal cord
7) LMN
8) Skeletal m. /motor plate
If a lesion is located above the medulla in the corticospinal tract, then the injury will be
Contralateral
If a lesion is located below the medulla in the corticospinal tract, then the injury will be
Ipsilateral
Clinical signs of a corticospinal tract lesion
1) inability to manipulate lips and tongue
2) deficit in forelegs(muscle weakness)
3) conscious proprioceptive deficit
4) Spastic paralysis
The origin of the rubrospinal tract is the….
Red nucleus
Which pathway is the rubrospinal tract a part of?
Lateral pathway
