Mechanosensation in an adipose fin.
Adipose fins are found on approximately 20% of ray-finned fish species. The apparently rudimentary anatomy of adipose fins inspired a longstanding hypothesis that these fins are vestigial and lack function. However, adipose fins have evolved repeatedly within Teleostei, suggesting adaptive function. Recently, adipose fins were proposed to function as mechanosensors, detecting fluid flow anterio...
متن کاملHydrodynamic and phylogenetic aspects of the adipose fin in fishes
The adipose fin on fishes is a highly conserved and enigmatic, small, non-rayed fin that has persisted from the Mesozoic on some basal teleosts such as salmonids. Using juvenile steelhead, Oncorhynchus mykiss (Walbaum, 1792), ranging from 5 to 18 cm standard length, we experimentally test the effects of adipose fin removal on swimming performance in a variable velocity flow chamber and quantify...
متن کاملAssaying mechanosensation.
C. elegans detect and respond to diverse mechanical stimuli using neuronal circuitry that has been defined by decades of work by C. elegans researchers. In this WormMethods chapter, we review and comment on the techniques currently used to assess mechanosensory response. This methods review is intended both as an introduction for those new to the field and a convenient compendium for the expert...
متن کاملMechanosensation * Miriam
Wild C. elegans and other nematodes live in dirt and eat bacteria, relying on mechanoreceptor neurons (MRNs) to detect collisions with soil particles and other animals as well as forces generated by their own movement. MRNs may also help animals detect bacterial food sources. Hermaphrodites and males have 22 putative MRNs; males have an additional 46 MRNs, most, if not all of which are needed f...
متن کاملTRP channels in mechanosensation.
Channels of the TRP superfamily have sensory roles in a wide variety of receptor cells, especially in mechanosensation. In some cases, the channels appear to be directly activated by mechanical force; in others, they appear to be downstream of a messenger pathway initiated by force on a non-channel sensor. A remaining challenge for most of these mechanosensory TRPs is to clarify the specific me...
