Laboratory Exercise 10: Anatomy and Physiology of the Spinal Cord
... The stretch reflex has one synapse between the sensory and motor neuron. The stretch reflex is initiated when the stretch receptors or proprioceptors are stretched. The stretch receptors are stimulated on one side, cause contraction of the muscle on that same side. This contraction is a protective r ...
