Hello,
Thanks for posting your query.
The inverse stretch reflex is triggered by the increased rate of muscle contraction and the increase in the length of the muscle fibres. After the stretching exceeds a particular length, the annulospiral receptor sends a signal, proportional to the amount and rate of stretch, to tell the muscle to contract. This is a safety mechanism to prevent the muscle being overstretched.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
Dr. Praveen Tayal.
