transport mechanisms Flashcards
what are the fastest fibers
A - alpha, then A-Beta
group 3 nocieceptors
A fibers
what fibers go to the lamina II and IV
A fibers
large mylinated fibers
A fibers
what tract does pain go up and down
tract of lissauer
what is faster proprioception or nocieception
proprioception
what fibers are responsible for the withdrawal reflex and how fast is it
A fibers 10-30 meters per second
what fibers are in the endoneural tube
A and C fibers
why type of nerves are most susceptible to compression
large mylinated nerves
what fibers are quick stabbing and sharp muscle proprioceptors
A fibers
what fibers are responsible for burning and aching
C fibers
what fibers are in the viscera and somite
C fibers
what fibers cause the pinpoint pain of the wrapper of viscera
A fibers
what fibers are responsible for convergence
C fibers
small, unmylinated fibers in the endoneural tube
C fibers
what fibers are in the microtublular network in the epineurium
trophic fibers (antegrade and retrograde)
what is the fastest axoplasmic fibers
antegrade (400mm/day)
what are the slower axoplasimic fibers
retrograde (1-3mm/day)
what axoplasmic fibers go from proximal to distal
antegrade
what axoplasmic fibers are for feeding of protiens and sugars
antegrade
what axoplasmic fibers go from terminal end to cell body
retrograde
what axoplasmic fibers are responsible for recycling (NGF and neurotransmitters)
retrograde
what axoplasmic fibers are responsible for neuroplasticity
retrograde
what axoplasmic fibers are responsible for making collateral circutis
retrograde
