Q. When a normal innervated skeletal muscle is stretched, the initial response is contraction, but with increasing stretch, the muscle suddenly relaxes because: (Solved)
1. with strong stretch, the efferent discharge is decreased
2. with strong stretch, the discharge from the annulospiral endings of afferent nerve fibres is inhibited
3. with strong stretch, there is decreased activity in the afferent nerve fibres from the Golgi tendon organs
4. with strong stretch, there is increased activity in the afferent nerve fibres from the Golgi tendon organs
5. because of reciprocal innervation, there is increased discharge in the afferent nerve fibres from the antagonists to the stretched muscle
- e. because of reciprocal innervation, there is increased discharge in the afferent nerve fibres from the antagonists to the stretched muscle
