Fish neuromast
WebJun 1, 1997 · To clarify when the free neuromasts of fish become functional, the neuromast formation in the embryonic development of the cod fish Gadus macrocephalus Tilesius was investigated. The initial appearance of placodes and an increase in the number and distribution of free neuromasts were followed using light microscopy and scanning … WebJan 1, 2013 · The fish lateral line system is unique in its ability to sense water flow with two types of receptors, the canal neuromast (CN) and superficial neuromast (SN). Both include mechanosensory hair cells in the skin that are coupled to an extracellular cupula, which is deflected by flow. Differences in the biophysics of these receptors cause them to ...
