posterior lateral line neuromast hair cell morphogenesis
The change in form (cell shape and size) that occurs when a posterior lateral line neuromast hair cell progresses from its initial formation to its mature state. A neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface.
