A hemicord spinal lesion shows ipsilateral loss of ___ and contralateral loss of___
ipsilateral vibration/proprioception and motor
contralateral pain/temperature
A small central cord lesion can damage spinothalamic fibers causing bilateral
sensory loss of pain and temperature
Posterior column lesion in the spinal cord causes loss of
vibration and position sense below the level of the lesion
Anterior cord damage is likely to damage the anterolateral path causing loss of
pain and temperature
muscle weakness in a child is most likely muscular dystrophy or polymyositis?
muscular dystrophy than polymyositis
Definition of Motor Unit
LMN and all the muscle fibers it innervates
Fasciculations mean
spontaneous twitching of all myofibers in affected motor unit
Fibrillations mean
spontaneous twitching of an individual myofiber
In spasticity increased tone is seen in these muscle groups
flexors of arms and extensors of legs
Rigidity marks what type of lesion
basal ganglia
A brisk jaw jerk indicates
lesion in the UMN above the trigeminal motor nucleus (mid-pons)
lesion above the level of the facial nucleus would cause
UMN paresis of face and body on the side contralateral to lesion
A pontine lesion involving facial nucleus or nerve and corticospinal tract would cause
LMN facial paresis ipsilateral to lesion and hemiparesis in body contralateral to lesion
A lesion between the facial nucleus and decussation of pyramids would cause
Hemiparesis contralateral to lesion and no facial weakness
A lesion below the decussation of pyramids would cause
hemiparesis ipsilateral to lesion

MS
A lesion in the pons causes eyes to deviate
away from side of lesion
The involvement of the medial lemniscus with sparing of spinothalmic tract points to a lesion in the

posterior cord syndrome loss of vibration and proprioception can be a form of neurosyphilis
Vitamin B12 deficiency could cause degeneration of what part of spinal cord
posterior column and corticospinal tract
Fredreich's ataxia affects these spinal cod tracts
posterior cord, corticospinal, and spinocerebellar
