It addresses the way in which movement of ions controls the cell shape and regulates ph. This all results in a significant saving of atp by the hair cell.
Which Movement Of Ions Produces Epsps In Cochlea Hair Cells. The open channels pass inward current, carried primarily by potassium and calcium ions, which depolarizes the hair cell and initiates the sensory signal. A) influx of na+ b) efflux of ca++ c) influx of k+ and ca++ d) efflux of k+ Acting like motor cells, outer hair cells produce forces that are driven by graded changes in membrane potential. At the base of the hair cells is a network of cochlear nerve endings, which lead to the spiral ganglion of corti in the modiolus of the cochlea.

[solved] which movement of ions produces epsps in cochlea hair cells?
The inner ear and cochlea¶. Acting like motor cells, outer hair cells produce forces that are driven by graded changes in membrane potential. Vibration of the stapes in the inner ear causes the vibration of the oval window at the base of the cochlea [1]. The spiral ganglion sends axons. This protein, known as prestin, is a member of a transporter superfamily slc26. Whereas the perilymph is rich in sodium ions, the endolymph is rich in potassium ions, which produces an ionic, electrical potential.

Auditory hair cells, which reside in the sensory epithelium of the cochlea and utricle, have bundles of cilia that transduce the energy of sound and motion to electrical impulses that travel to the brain over the acoustic nerve. The hair cells are held in place by the reticular lamina, a rigid structure supported by the pillar cells, or rods of corti, which are attached to the basilar fibres. Hair cells adapt to sustained bundle deflections by adjusting channel open probability back toward the resting value.

The afferent, bipolar neurons that convey auditory information travel from the cochlea to the medulla, through the pons and midbrain in the brainstem, finally reaching the primary auditory cortex in the temporal lobe. Whereas the perilymph is rich in sodium ions, the endolymph is rich in potassium ions, which produces an ionic, electrical potential. As the footplate of the stapes presses on the oval window at the base of the cochlea, it pressurizes the fluid in the scala vestibule or vestibular canal, a channel that runs the length of the cochlear spiral.given that the cochlea is a closed system, this pressure has to be dissipated somehow, or the stapes footplate would be pushing.
