Samar Review Flashcards
Parts of ALS
Neospinothalamic= fibers to S1, S2 for LOCALIZATION Paleospinothalamic= spinoreticular--> anterior cingulate and insular cortex
What makes you MAD when you get hurt?
Paleospinothalamic= spinoreticular
Spinomesencephalic
Mesencephalic= midbrain PAG
MODULATION OF PAIN
5 parts of ALS
- Spinothalamic
- Spinoreticular
- Spinomesencephalic
- Spinobulbar
- Spinohypothalamic
spinobulbar
spino-olivary
Bulbo= olivary
spinohypothalamic
Autonomic expression of pain
Medial motor
Axial muscles
Medial motor- what influences this region
Proprioception synapses here
Reticulospinal, vestibulospinal, anterior corticospinal
What affects sympathetics
hypothalamospinal fibers
What synapses in Lamina II
Raphe- carry serotonergic
What part of hypothalamus sends input to sympathetics
paraventricular
Parabrachial nucleus
“whitish between the black”
spinoreticular tract. motivation/emotional aspect of pain
DRG above C6?
accessory cuneate nucleus–> vermis granule layer
Descending MLF
(below abducens)–> spinal cord to cervical region medial neurons. Bilateral projections
Ascending MLF
to eye muscles
Restiform body
Cuneocerebellar
(clarke’s nucleus is equivalent in lower area)
Bodies in accessory cuneate nucleus and clarke’s nucleus
Olivo cerebellar
climbing fibers to purkinje cells
Neurosyphilis
wipes out pretectal region (light reflex) but WONT affect conversion (pupil WILL constrict to that).
Smooth pursuit
vestibular nuclei to CN III
Vestibular nuclei control
VOR and smooth pursuit to CN III
Horizontal gaze
abducens
convergence
supraculomotor area (to medial rectus AND EDW)
pretectal region
light reflex
Modality means?
pain temp crude touch fine touch vibration etc
