| 1. | Most arachnids lack extensor muscles in the distal joints of their appendages.
|
| 2. | Finger flexor and extensor muscles are non-functional making grip of the implement difficult.
|
| 3. | The extensor muscles are inhibited to prevent competition between the extensor and flexors.
|
| 4. | Most often, the extensor muscles become painful due to tendon breakdown from over-extension.
|
| 5. | The anterior five segments of the crayfish house the massive flexor and extensor muscles.
|
| 6. | Conversely, an extensor muscle is the agonist in extension and the antagonist in flexion.
|
| 7. | The body maintains the balance between the tone of flexor and extensor muscle groups.
|
| 8. | Meanwhile, your shoulder extensor muscles contracted, so their receptors rested.
|
| 9. | It happens because flexor muscles in the hand are so much stronger than extensor muscles.
|
| 10. | These flattened tendons ( aponeurosis ) of extensor muscles span the proximal and middle phalanges.
