Stereocilia of frog inner ear

Stereocilia (or stereovilli) are non-motile apical modifications of the cell, which are distinct from cilia and microvilli, but closely related to the latter.

In structure, they are longer than typical microvilli, and have more of the characteristics of the cellular membrane proper. Like microvilli, they contain actin filaments, distinguishing them from microtubule-containing cilia.

They are found in three regions of the body:

• the ductus deferens
• the epididymis (see stereocilia (epididymis) for more details). Some sources consider epididymal stereocilia to be a variant of microvilli,^[1] rather than their own distinct type of structure.
• the sensory (hair) cells of the inner ear (see stereocilia (inner ear) for more details)
