AI Article Synopsis
- The study examined the ultrastructure of pit organs and neuromasts in the skin of adult giant salamanders (Andrias davidianus) using transmission electron microscopy.
- Neuromasts and pit organs exhibit differences in synapses, kinocilia arrangement, and the extent of separation between sensory cells and supporting cells, suggesting they have complementary functions.
- The neuromasts in A. davidianus have unique features compared to other salamanders, including kinocilia orientation, supporting cell intrusion, thickened synaptic membranes, varied synaptic sphere distribution, and lack of a cupula.
Article Abstract
The ultrastructure of two kinds of mechanoreceptive organs, pit organs and neuromasts, in the skin of adult giant salamanders (Andrias davidianus) was studied by transmission electron microscopy. Neuromasts and pit organs differ in their types of synapses, the spatial distribution of kinocilia on sensory cells, and in the degree to which sensory cells are separated by processes of the supporting cells; the two organs probably serve complementary functions. The neuromasts in A. davidianus differ from those of other salamanders in the orientation of kinocilia, in the extent of intrusion of supporting cells into the sensory layer, in the degree of thickening of the synaptic membranes, in the distribution of synaptic spheres, and by the absence of a cupula.
