peripheral NS

Question 1

A fibers

Answer 1

large fibers, myelinated, high conduction rate

alpha, beta, gamma, and delta subsets

Question 2

what do A alpha fibers detect?

Answer 2

alpha motor neurons, muscles spindle primary endings (low threshold stretch), golgi tendon organs (tension, stretch of tendon), touch

Question 3

what do A beta fibers detect

Answer 3

muscle spindle secondary endings (change in muscle length), kinesthesia, touch

Question 4

what do A gamma fibers detect

Answer 4

gamma motor neurons, pressure, touch

Question 5

what do A delta fibers detect?

Answer 5

pain, pressure, temp, touch

Question 6

B fibers

Answer 6

medium, myelinated, reasonably fast

preganglionic fibers of ANS

Question 7

C fibers

Answer 7

small, unmyelinated, slow conduction rate
postganglionic fibers of sympathetic NS
exteroreceptors for pain, temp, touch
