Now that we've got the calf extended, we have to get it flexed back. Sensory input from the quadriceps telling the cord that the quads are fully contracted is sent to the cord. Once the stimulus is detected at the cord, signals are sent to the two groups of muscles via two interneurons. One signal tells the quads to relax and the other tells the hamstrings to contract, returning the calf to its resting position. DTR's oppose stretch reflexes and are used diagnostically to determine how a part of a person's neurological health is doing.
Output is sent to the side where the pain is felt AND to the opposite side.
Tabulated, below, is a non-inclusive summary of reflexes used in clinical examinations. Figure 17 illustrates a non-traditional reflex. This is the Perez reflex. It is used when one wishes to get urine from a baby.
