| Column 1 | Column 2 (memorize) |
|---|---|
| The 16 types of afferents from the hand can be grouped into what functional groups? | 1). Cutaneous mechanoreceptors, 2). proprioceptors, 3). lightly myelinated and unmyelinated afferents that respond to warming and cooling, and 4). lightly myelinated and unmyelinated afferents that repond to noxious and pruritic stimuli. |
| What is the I-IV and A-C classification for the primary spindle afferent axon type? | Ia / A-alpha |
| What is the I-IV and A-C classification for the golgi tendon organ afferent axon type? | Ib / A-alpha |
| What is the I-IV and A-C classification for the cutaneous mechanoreceptive afferent axon type? | II / A-beta |
| What is the I-IV and A-C classification for the "cold" thermoreceptive / pricking pain afferent axon type? | III / A-delta |
| What is the I-IV and A-C classification for the "warm" thermoreceptive / burning pain afferent axon type? | IV / C |
| What fibers from the A-C classification are myelinated? | All of the A fibers (I-III). |
| What fibers from the A-C classification are unmyelinated? | The C fiber (IV). |
| What is the diameter of A-alpha (Ia/Ib) fibers? | 12-20 microns |
| What is the diameter of A-beta (II) fibers? | 7-12 microns |
| What is the diameter of A-delta (III) fibers? | 2-6 microns |
| What is the diameter of C fibers? | .3-1.5 microns |
| What is the conduction velocity of A-alpha (Ia/Ib) fibers? | 72-120 m/s |
| What is the conduction velocity of C (IV) fibers? | .5-1.2 m/s |
