WebThere are a great many varieties of mechanical receptors in animals, but best known are the receptors that mediate touch, the variety of hair cell receptors in vertebrates that mediate hearing (the acoustico-lateralis system), and the muscle spindle proprioceptors that monitor the state of muscle contraction. The basic mechanism by which a stimulus is converted … WebOverview. Stimulation, in general, refers to how organisms perceive incoming stimuli. As such it is part of the stimulus-response mechanism. Simple organisms broadly react in three ways to stimulation: too little stimulation causes them to stagnate, too much to die from stress or inability to adapt, and a medium amount causes them to adapt and grow …
