Summary Introduction
To determine:
The reflex that occurred when a weight lifter, who is straining to lift the weight above his head, brings the barbell to his chests, and then drops it because the muscles of his arm relaxed.
Introduction:
Reflex is the term given to instantaneous and automated response to a particular stimulus. This kind of stimulation causes the utilization of the reflex arc. Reflex arc is the path followed by the signals which are induced by specific stimulation. There are two different types of reflexes namely monosynaptic reflex that includes the postural reflex and stretch reflex, and the polysynaptic reflex that includes tendon reflex, withdrawal reflex, crossed extensor reflex.
