Exercise # 3 Human Reflexes Rahn and Harvey 1) Define reflex . On the chalkboard, diagram the components of a reflex arc. Are all reflexes considered unlearned responses; why or why not? What is a monosynaptic reflex? On the chalkboard, diagram the monosynaptic reflex that is seen in skeletal muscle. Diagram and explain what occurs in the antagonistic muscle. Bernard and Morgan 2) What is the H-Reflex? Diagram the components of this reflex. What is the physiologic importance of this pathway? What is an EMG? Present your raw data for: a) H- wave threshold c) H- wave maximum b) M- wave threshold d) H- wave abolished. Selye and Starling 3) Present your data that compares the stimulator voltage setting VERSUS a) the H- wave threshold, b) M-wave threshold, c) maximal H-wave and d) H-wave abolished. Based on your collected data, what conclusions can you make about the effect of stimulus voltage and magnitude of the EMG (and explain how you arrived at these conclusions)? What similarities can be made with the previous lab exercise
