WebSensory Reception HEARING IN MAMMALS Auditory structure of mammals. In the mammals the ear reaches its highest level of development, with well-differentiated divisions of outer ear, middle ear, and inner ear. Except in some of the sea mammals, in which certain modifications and degenerations have taken place, these structures carry out their … In mammals, the auditory hair cells are located within the spiral organ of Cortion the thin basilar membranein the cochleaof the inner ear. They derive their name from the tufts of stereociliacalled hair bundlesthat protrude from the apical surfaceof the cell into the fluid-filled cochlear duct. See more Hair cells are the sensory receptors of both the auditory system and the vestibular system in the ears of all vertebrates, and in the lateral line organ of fishes. Through mechanotransduction, hair cells detect movement in their … See more In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body.

Web29 Mar 2024 · The stereocilia of the inner ear hair cells are microvilli-derived and unique cell structures that represent the gate for stimulus detection and correlate anatomically with distinct cochlear functions, including mechanoelectrical transduction, cochlear amplification, adaptation, frequency selectivity and tuning [ 27 ]. Web5 Mar 2024 · The sense of hearing depends on mechanically sensitive ion channels located near the tips of the stereocilia on the sensory hair cells of the inner ear ( 1 ). When an acoustic stimulus causes these mechanoelectric transduction (MET) channels to be activated, the flow of potassium and calcium ions into the cell increases ( 2 ).
