| Q. |
When a normal innervated skeletal muscle is stretched, the initial response is contraction, but with increasing stretch, the muscle suddenly relaxes because: |
| A. | with strong stretch, the efferent discharge is decreased |
| B. | with strong stretch, the discharge from the annulospiral endings of afferent nerve fibres is inhibited |
| C. | with strong stretch, there is decreased activity in the afferent nerve fibres from the Golgi tendon organs |
| D. | with strong stretch, there is increased activity in the afferent nerve fibres from the Golgi tendon organs |
| E. | because of reciprocal innervation, there is increased discharge in the afferent nerve fibres from the antagonists to the stretched muscle |
| Answer» E. because of reciprocal innervation, there is increased discharge in the afferent nerve fibres from the antagonists to the stretched muscle | |
