Lateral Motor Systems (Descending) Flashcards
The site of origin for Lateral Corticospinal Tract
The primary motor cortex and other frontal and parietal areas
The site of decussation for the Lateral Corticospinal Tract
Decussation in the pyramidal cells of the cervicomedullary junction
Where does the termination of the Lateral Corticospinal Tract end
In the entire spinal cord, predominantly at the cervical and lumbosacral enlargements (in the lateral intermediate zone and lateral motor nuclei of the anterior horn)
What is the function of the Lateral Corticospinal Tract
Movement of contralateral limbs
The site of origin for the Rubrospinal Tract
Red Nucleus (in the midbrain)
The site of decussation for the Rubrospinal Tract
Ventral tegmental decussation (in the midbrain) then moves down spine through the lateral column
Where does the termination of the Rubrospinal Tract end
Cervical spinal cord (lateral intermediate zone and lateral motor nuclei of the anterior horn)
What is the function of the Rubrospinal Tract
Movement of contralateral limbs (UE?)
What motor tracts are included in the lateral motor systems
