What runs in the Spinothalamic tract?
|
Ascending
Pain and Temperature |
|
|
What are the 2 substracts of the Spinothalamic tract and what do they do?
|
Neospinothalamic - fast faithful localisation of sharp pain from superficial structures
Paleospinothalamic (BRF) - Slow non-specific dull pain from deep structures |
|
|
Where does the Spinothalamic tract cross and what is the clinical relevence?
|
Crosses in the spinal cord at the Ventral White Commissure, thus a hemi section results in loss of pain/temp from the CONTRAlateral side.
|
|
|
What runs in the Dorsal Column tract?
|
Asending
Tactile and CONSCIOUS Proprioception |
|
|
What are the 2 subtracts of the Dorsal Column Tract?
|
Medial Gracile for lower limbs
Lateral Cuneate for upper limbs |
|
|
Where does the Dorsal Column Tract cross and what is the clinical relevance?
|
Synapses in the Brainstem, then crosses.
Thus a hemi-section results in loss of Tactile and Conscious Proprioception from the IPSIlateral side. |
|
|
What runs in the Spinocerebellar tract?
|
Ascending UNCONSCIOUS proprioception
|
|
|
Where does the Spinocerebellar tract cross and what is the clinical significance?
|
It doesen't cross. A hemi-section would result in loss of proprioception on the ipsilateral side.
|
|
|
Which tracts provide "Basic Motor control" and what is meant by this?
|
Vestibulospinal Tract and Reticulospinal Tract.
They provide posture and autonomics. |
|
|
What is the clinical significance of a hemi-section to the Vestibulospinal or Reticulospianl tracts?
|
Loss of posture
Body lateropulsion Small loss of Visceral control |
|
|
What is found in the Corticospinal tract?
|
Descending
Skilled Motor |
|
|
Where does the Corticospinal tract cross and what is the clinical significance?
|
90% cross in the Pyramid of the Brainstem. Hemi-section would lead to loss of skilled movements.
|
|
|
What is found in the Rubrospinal Tract?
|
Descending
Skilled motor Helper to Corticospinal |
|
|
What spinal root is being tested in the Bicep reflex?
|
C5 (C6)
|
|
|
What spinal root is being tested in the Brachioradialis reflex?
|
C6
|
|
|
What spinal root is being tested in the Tricep reflex?
|
C7
|
|
|
What spinal root is being tested in the Patellar reflex?
|
L4
|
|
|
What spinal root is being tested in the Achilles reflex?
|
S1
