Descriptions
The rightmost ventral row four develops in an unique way. For opisthe it is entirely generated by the oral primordium, for proter from a basal bodies field, mainly originating from oral primordium. The old long ventral row four does not contribute to the forming of new row four, but is resorbed while the new row is generated. (ref. ID; 7423)
