Transport Mechanisms Flashcards
what is the soma of the neuron made up of?
neurotransmitters
what is another term for axon
endoneural tube
what are the fastest fibers
what are second
A fibers
C fibers
A fibers are the fastest
which certain kind of A fibers is faster
alpha faster
beta fast
A fibers detect what
quick stabbing and sharp muscle proprioceptors
what is the size of an A fiber
large
what fiber is myelinated
A
what is the size of C fibers
small
what fiber is unmyelinated
C
A (fastest) and C (fast) are both which type impulse
message impulse
what is the group of nociceptors and lamina are associated with A fibers
group 3
lamina 2 and 4
pain goes up and down what tract
tract of lissauer
what are the two different transport mechanisms for neurons?
message - FAST - axon
trophic - SLOW/AXT - microtubular network
which fibers are found in joints
A fibers
which fibers are found in viscera
C fibers
what group of nociceptors and lamina is associated with C fibers
group 4
lamina 2
what fiber is associated with convergence? withdrawal reflex?
convergence - C fibers
withdrawal reflex - A fibers
how fast do A fibers travel
10-30 meters per second
substance P and inflammation are associated with which fibers
C fibers
what are the different types of SLOW axoplasmic transport (trophic)
antegrade - fast
retrograde - slow
how fast are axoplasmic transport trophic antegrade fibers
400 mm per day
how fast are axoplasmic transport trophic retrograde fibers
1-3 mm per day
what terms are associated with fast antegrade axoplasmic transport
feeding - protein/sugar proximal to distal fast axoplasmic transport bulk slow
what terms are associated with slow retrograde axoplasmic transport
terminals to cell body recycling neuroplasticity collateral fibers slower
