Name the Descending Spinal Cord Tracts
Vestibulospinal
Lateral Corticospinal
Anterior Corticospinal
Rubrospional
Medullary Reticulospinal
Pontine Reticulospinal
Name the mixed pathways orginating from the brainstem
Medial Longitudinal Fasciculus
Tectospinal
What is the function of the Dorsal Column
carries conscious sensory info to the cortex regarding:
Discriminative touch
Pressure
Vibration
Proprioception
Kinesthesia
Where does the Dorsal Column orginate
dorsal horn
What is the destination of the Dorsal Column
Primary somatosensory cortex. A major sensory pathway
If you have a complete severance of the Dorsal Column, what effect would it have on sensation
Bilateral loss of sensation below levelof injury
If you have a hemi-lesion below the decussation, what effect would it have on sensation
Ipsilateral loss
If you have hemi-lesion in the brainstem above the medulla, what effect would it have on sensation
Contralateral sensory loss
If you have a lesion in the cortex, what effect would it have on sensation.
Contralateral sensory loss
Where does teh dorsal column decussate
caudal medulla
What type of tract is the Lateral Spinothalamic tract
Ascending
What is the function of the Lateral Spinothalamic tract
sensory info focusing on pain and temperature
Where does the Lateral Spinothalamic tract orginate
Dorsal horn
Where does the Lateral Spinothalamic tract decussate
as soon as it enter the spinal cord
What is the destination of the Lateral Spinothalamic tract
Somatosensory Cortex
What effect would a complete severance of Lateral Spinothalamic tract have on sensation
Bilateral sensory loss below level of the lesion
What effect would a Hemi-lesion on the Lateral Spinothalamic tract have on sensation:
1. At level of lesion
2. Below level of lesion
1. Bilateral sensory loss
2. contralateral sensory loss
A unilateral lesion in the somatosensory cortex would have what effect
Contralateral sensory loss
