Elongate, usually colorless cells or extensions of cells found at branch apices, increases surface area for nutrient and gas exchange and may protect the cells from herbivory

The receptor cells found in the inner ear. Hair cells bear hair-like projections, cilia, which vibrate in response to sound or movement of the head. Movement of the cilia leads to the opening of ion channels in the cells and to the production of brief electrical signals.

Also known as cilia, these line the cochlea and, in a person with normal hearing, transmit the incoming sound signal to the auditory nerve, which in turn sends it to the brain. In many people with hearing loss, the hair cells are diminished in number, damaged, or even totally missing.

Sensory cells in which bending of stereocilia (the "hairs") causes a change in membrane potential.

sensory cells of the inner ear, which are topped with hair-like structures (stereocilia), which transform the mechanical energy of sound waves into nerve impulses.

The hair cells in the inner ear sense the pitch and intensity of sound waves that travel through the fluid of the inner ear. In most instances of deafness, the hair cells or some part of the anatomy associated with them do not function properly and cannot send signals accurately to the brain. The cochlear implant attempts to mimic the function of the hair cells by generating a signal similar to what the brain might normally receive from the inner ear.

Cells present in the cochlea that convert the mechanical energy present in sound vibrations into electrical activity. Hair cells have cilia on one side which are stimulated by movement and on the other side are connected to fibers of the VIIIth cranial nerve, which carries the impulse to the brain.

The auditory receptors in the cochlea, lodged between the basilar membrane and other membranes above.

Found in the organ of Corti in the cochlea of the inner ear, these are the specialized receptors of hearing. The name refers to stereocilia, bundles of hairlike projections jutting upward from the cells. When the stereocilia are moved by sound vibrations, the hair cells translate this mechanical stimulation into an electrical nerve impulse that is carried to the brain by the auditory nerve.

In audition, hairlike receptors in the cochlea that bend due to vibration of the basilar membrane and then send electrical impulses to the brain. See also basilar membrane, cochlea.

Sensory cells in the cochlea which transform the mechanical energy of sound into nerve impulses. Each ear has 23,500 hairs in the cochlea.

Sensory cells in organ of Corti; transducers of sound waves into nerve impulses.

Epithelial cells with stereocilia or kinocilia found in the vestibulocochlear system
