Abstract
The utility model discloses a knee jerk reflex electric simulated teaching aid which comprises a base. A truncus plate is fixed on the base. The truncus plate is provided with an electric motor, a sensory receptor, an afferent demonstration lamp, an efferent demonstration lamp, a nerve centre demonstration lamp, a program controller, a sensory receptor key, a power supply, an afferent nerve key, a nerve centre key, an efferent nerve key and a sensory receptor demonstration lamp. A motor shaft of the electric motor is provided with a crus plate. The sensory receptor is arranged at the position on the truncus plate, which is close to the electric motor. The knee jerk reflex electric simulated teaching aid is used according to the following steps that the sensory receptor key is closed; the sensory receptor is knocked by a wooden hammer; the sensory receptor demonstration lamp emits light to demonstrate that a knee is stimulated; the afferent nerve key is closed; the afferent demonstration lamp is lighted so as to express that a nerve receives an afferent signal; the nerve centre key is closed; the nerve centre demonstration lamp is lightened to demonstrate that a nerve centre receives a nerve signal; the efferent nerve key is closed; the efferent demonstration lamp is lightened so as to express that an efferent nerve sends out the signal; the electric motor works; and a knee jerk is demonstrated.
