Abstract/OtherAbstract:
|
Lateral line neuromasts of the bullseye Parapriacanthus ransonetti and the cardinal fish Apogon cyanosoma were examined by scanning electron microscopy. Neuromasts showed large numbers of degenerating hair cells and immature hair cells, suggesting a high degree of hair cell turnover. New hair cells were mainly produced in pairs (fewer than 5% appear singly), the two cells of a pair having opposite but parallel orientations of their mechanosensitive axes. It is suggested that each pair results, directly or indirectly, from a single mitosis. The results further suggest that the axis of mitosis is one of the factors which determine the direction of the hair cell axis of mechanosensitivity. |
