Stereocilia
The term Stereocilia is an unfortunate misnomer since these structures are in no way related to cilia.

Stereocilia (or stereovilli) are non-motile apical modifications of the cell, that are distinct from cilia and microvilli, but closely related to the latter.
In structure, they are much longer and thicker than typical microvilli, form single "finger-like" projections that may be branched, and have more of the characteristics of the cellular membrane proper. Like microvilli, they contain actin filaments and lack an axoneme, distinguishing them from 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)
