General Information
Term	stereocilium	ID (Ontology)	GO:0032420 (Gene Ontology)
Definition	An actin-based protrusion from the apical surface of auditory and vestibular hair cells and of neuromast cells. These protrusions are supported by a bundle of cross-linked actin filaments (an actin cable), oriented such that the plus (barbed) ends are at the tip of the protrusion, capped by a tip complex which bridges to the plasma. Bundles of stereocilia act as mechanosensory organelles.[ PubMed:15661519 PubMed:7840137 ]
