A spinal reflex is a reflexive action mediated by cells in the spinal cord, bypassing the brain altogether. A classic example is the kneejerk or patellar reflex, where the leg jerks when the kneecap is struck with a brisk tap. spinal reflex will bypass the brain and is an action only by the cells in the spinal cord.
As discussed earlier, a reflex involves at least 2 or 3 neurons. The typical components of a reflex are shown in Figure 13.12. The reflex shown in this figure is called a 3-neuron reflex because it requires three types of neurons: a sensory, an interneuron, and a motor neuron.heir function, like that of stretch reflexes, is the coordination of muscles and body movements. The deep tendon reflex involves sensory neurons, interneurons, and motor neurons. The response reverses the original stimulus therefore causing relaxation of the muscle stimulated.
