part of neuromast hair cell differentiation anterior lateral line neuromast development anterior lateral line neuromast hair cell differentiation GO:0048903 The process in which a relatively unspecialized cell acquires specialized features of an anterior lateral line neuromast hair cell. Neuromast hair cells are the sensory receptors of the neuromast and are located in a portion of the neuromast called the sensory strip. Each hair cell of the neuromast is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. There are approximately seven hair cells within each neuromast, with each hair cell innervated by afferent and efferent neurons. biological_process
