Nerve Fiber Classification Flashcards
Which fibers does motor to intrafusal and extrafusal
A-beta fibers
Which fiber does sensory to pain and temperature
C-fibers/IV fibers
Which fiber does sensory to golgi tendon organs?
Ib fibers
Erlanger and Gasser Nerve Fiber Classifications
A-alpha A-beta A-gamma A-delta B C
LLoyd and Hunt Nerve Fiber Classifcations
Ia, Ib, II, III, IV
Which fibers are the fastest
A-alpha/Ia
Electrodiagnostic studies evaluate only what type of nerve fibers?
Ia (large, myelinated) fibers
Principal receptors for pain
C and A-delta fibers
Which is smaller and faster? A-delta fibers or C fibers
C is smaller than A-delta
A-delta is faster than C
Smallest nerve fibers
IV fibers/C fibers
Slowest nerve fibers
IV fibers/C fibers
Function of Ia fibers
Sensory muscle spindle afferents
Which nerve fiber does motor to intrafusal fibers
A-gamma fibers
Largest Sensory/motor neurons
Ia sensory fibers/A-alpha fibers
Which fibers are unmyelinated
B and C fibers
