Explanation The differences between the stretch reflex and Golgi tendon reflex includes the stretching of muscles and sensation is perceived by sensory neurons that are wrapped around intrafusal muscle fibers of the spindle fibers in stretch reflex. The signal reaches the brain from the spinal cord by the transfer of signals across the synapses of alpha motor neurons in the brain. This signal reaches extrafusal muscle fibers which lead to their contraction...
