(23 cards)
Reticulospinal Tract-contra, ipsi or bilateral
bilatera
Reticulospinal Tract- where does it come from and where does it end
comes from reticular formation in brainstem and ends at the LMN in spinal cord
Reticulospinal Tract- what does it control
posture and gross limb movements
*Medial Vestibulospinal Tract- ispsilat, contralat, bilat
bilateral
*Medial Vestibulospinal Tract- where does it come from
comes from the medial vestibular nucleus (inner ear) and ends at the LMN in the spinal cord
*Medial Vestibulospinal Tract- what does it control?
Modulates of head and neck extensor muscle tone (being able to keep your head up)
*Medial Vestibulospinal Tract- clinical relevance?
vertigo
Medial corticospinal tract- ispi, bi, or contralateral
ipsilateral
Medial corticospinal tract- where does it come from and where does it end
comes from the primary motor cortex and ends at the LMN in spinal cord
Medial corticospinal tract- LMN to where, what is the function
LMN to neck, shoulder and trunk muscles
*Lateral Vestibular tract - ispsi, contra or bilateral
ispilateral
*Lateral Vestibular tract- where does it come and where does it end?
comes from the lateral vestibular nucleus and ends at the LMN in the spinal cord
*Lateral Vestibular Tract- what does control
modulates of extensor muscle tone in trunk and limbs
*Lateral Vestibular Tract- clinical relevance
Vertigo
