- Characteristics of sensory nerve fibres
| Sensory fibre | Myelinated axons | Diameter (ยตm) | Conduction velocity (m/s) | General Function |
|---|---|---|---|---|
| Aฮฑ | Yes | 13-20 | 80-120 | muscle spindle primary endings, golgi tendon organs, touch (and alpha motor neurons) |
| Aฮฒ | Yes | 6-12 | 33-75 | Discriminative sensitivity to mechanical stimuli (touch, vibration) |
| Aฮณ | Yes | 4-8 | 15-40 | Touch, pressure (and gamma motor neurons) |
| Aฮด | Thin | 1-5 | 3-30 | "rapid" pain, crude touch, pressure, temperature |
| B | No | 1-3 | 3-14 | preganglionic autonomic |
| C | No | 0.3-1.5 | 0.5-2.0 | "slow" pain, touch, pressure temperature (and postganglionic autonomic) |
