WebSensation is the activation of sensory receptors at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern involving awareness. Perception is dependent on sensation, but not all sensations are perceived. Receptors are the structures (and sometimes whole cells) that detect sensations. WebThe sensory epithelia of the inner ear are composed of a regular mosaic of hair cells, interspaced by supporting cells. These two cell types derive from a pool of sensory-competent (or prosensory) cells, which are produced at early stages of ear development.
