"The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound [goid 7605] [pmid 12588794] [evidence IMP]; The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound [goid 7605] [pmid 11398101] [evidence IMP]; The process by which the anatomical structures of the inner ear are generated and organized. Morphogenesis pertains to the creation of form. The inner ear is the structure in vertebrates that contains the organs of balance and hearing. It consists of soft hollow sensory structures (the membranous labyrinth) containing fluid (endolymph) surrounded by fluid (perilymph) and encased in a bony cavity (the bony labyrinth). It consists of two chambers, the sacculus and utriculus, from which arise the cochlea and semicircular canals respectively [goid 42472] [evidence IEA]; Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light [goid 45494] [pmid 11398101] [evidence IMP]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus [goid 50896] [evidence IEA]; The series of events required for an organism to receive an orientational stimulus, convert it to a molecular signal, and recognize and characterize the signal. Equilibrioception refers to a combination of processes by which an organism can perceive its orientation with respect to gravity. In animals, stimuli come from labyrinth system of the inner ears, monitoring the direction of motion; visual stimuli, with information on orientation and motion; pressure receptors, which tell the organism which body surfaces are in contact with the ground; and proprioceptive cues, which report which parts of the body are in motion [goid 50957] [pmid 12588794] [evidence IMP]; The process whereby relatively unspecialized cells, acquire specialized structural and/or functional features of inner ear receptor cells. Inner ear receptor cells are mechanorecptors found in the inner ear responsible for transducing signals involved in balance and sensory perception of sound [goid 60113] [evidence IEA]"
