Hairy Hearing

Courtesy SPL / Photo Researchers, Inc.

Inner ear hair cells. Colored scanning electron micrograph (SEM) of sensory hair cells from the organ of corti, in the cochlea of the inner ear. These cells are surrounded by a fluid called the endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause these hairs to move. The movement is converted into an electrical signal, which is passed to the brain. The V-shaped arrangement of hairs lies on the top of a single cell. Magnification: x21,000 when printed 10cm wide.
