The cephalic sensory organ is a superficial sensory receptor located between the velar lobes at the level of the shell aperture. Three cell types make up this sensory area: (1) six flask-shaped cells bearing numerous cilia: (2) adjacent supporting or accessory cells which have numerous, often branched, microvilli; and (3) vacuolated cells which occupy the center of the area. The flask-shaped cells appear to be the sensory units. These cells have a deep invaginated lumen, with ciliar arising… CONTINUE READING
