Summary Introduction

Introduction:

Stretch reflex is monosynaptic reflex and gets activated upon the stretching of the muscle fibers. The stimulus causes the contraction and relaxation of the muscles as analyzed by the sensory neurons that are intercoiled along the intrafusal muscle fibers. The signals from the sensory neurons in the spinal cord are intercepted by the alpha motor neurons present in the muscle fibers.
