Table 1 Classification of mechanoreceptors, by Freeman and Wyke [17]
From: Morphological study of mechanoreceptors in collateral ligaments of the ankle joint
Type | Name | Feature | Size (μm) | Characteristics |
|---|---|---|---|---|
I | Ruffini | Round shaped, thinly myelinated, connected by nerve fibers; | 100 × 40 | Low threshold, slowly adapted |
II | Pacini | Column or cone shaped, thickly myelinated; | 280 × 120 | Low threshold, rapidly adapted |
III | Golgi | Spindle shaped, thinly myelinated, connected by thicker nerve fibers | 600 × 100 | Low threshold, slowly adapted |
IV | Free nerve endings | Non-myelinated, irregular; | diameter 0.5 ~ 5 | Transmit nociceptive sensation |
