Description

The present observations revealed the ultrastructural differences between the receptor cell of the lateral-line canal organ and that of the small pit organ.The chief differences are asfollows: 1.While the sensory hairs protruding from the top of the receptor cell of the former organ are composed of a few number of stereocilia and one kinocilium, those of the receptor cell of the latter organ are made up of a number of microvilli (stereocilia) only, and apical part of the cell lacks the dense material, cuticle.2.Nerve endings on the basal surface of the receptor cell of the former organ are separated into two different types, viz., non-granulated and granulated.However, nothing but the non-granulated type of the nerve ending is discernible in the latter organ.
