VERIFIED) | ALREADY GRADED A+ | LATEST
EDITION
What are A fibers? - ans -- located in the axon
-message impulses
- quick, stabbing and sharp muscle proprioceptors
-LARGE, myelinated and fast
- Group III nocipetors
-Lamina II and IV
What are C fibers? - ans --deep - located in the axon
-Deep viscera and something, substance P inflammation
-small, unmyleinated
-Group IV and Lamina II
-convergence
What are antegrade fibers? - ans -400mm/day
PROXIMAL TO DISTAL
Tropic message- slow but these are the fastest
"Passing out the food"
Allodynia? - ans -Pain due to stimulus which does not normally provoke pain
What is Geisel syndrome? - ans -Automimmue attack on Ci transverse ligaments
What happens when there is a acute pathological nerve compression? - ans -!.
Vascular -- obstruction
2. Edema--- hyppoixa which can lead to necrosis, the threshold is lowered but an
increase in action potential
3. Facilitate-- spillover, ascending inhibition, systemic event
, What happens in chronic pathological nerve compression? - ans -1. Axoplasmic
transport aberration -- retrograde and antegrade-- there is dimished nerve
transmission and wallerian degeneration (distal degeneration)
This is a local event because there will be local tissue death -- food is not getting
to the target tissue
What is the nerve compression theory? - ans -Invented by DD
Subluxation results in altered nerve transmission of nerve energy, this can lead to
altered transmission
This can alter tone
This is from a structural cause-- ex: IVF encroachment
What is Axoplasmic aberrations theory? - ans -ONE nerve or plexus with
decreased protein supply in micrtubular network
Loss of tropic function( food), caused by nerve compression, results in wallerian
degeneration and local tissue death
Ex: decreased DTR due to nerve compression
What is neurodystrophic theory? - ans -Created by seyle
Stress alters neuroendoncrine-- decreases immunity-- fixations
Descreases resistance
Immunity is forfeited in sympathetic
Who developed the "altered gamma gain" - ans -Korr
What is the altered gamma gain? - ans -If in the thoracic spine its causes
hypersympatheticotonia
Muscle deafferentation descreased CNS
About approxiation of muscle attachments and unanticipated giving way can
cause an altered state
Both cause sudden muscle slack-- "spindle silence"--> CNS increases Hamm
discharge causing spasms
Small trauma can causes massive spasm-- "bracing or splinting of mm"
What is the proprioceptive insult theory? - ans -This is the "weekend warrior"
accident
Asymmetrical
