Slow Ca2+ dynamics in pharyngeal muscles in Caenorhabditis elegans during fast pumping.
The pharyngeal muscles of Caenorhabditis elegans are composed of the corpus, isthmus and terminal bulb from anterior to posterior. These components are excited in a coordinated fashion to facilitate proper feeding through pumping and peristalsis. We analysed the spatiotemporal pattern of intracellular calcium dynamics in the pharyngeal muscles during feeding. We used a new ratiometric fluoresce...
متن کاملOptical silencing of body wall muscles induces pumping inhibition in Caenorhabditis elegans
Feeding, a vital behavior in animals, is modulated depending on internal and external factors. In the nematode Caenorhabditis elegans, the feeding organ called the pharynx ingests food by pumping driven by the pharyngeal muscles. Here we report that optical silencing of the body wall muscles, which drive the locomotory movement of worms, affects pumping. In worms expressing the Arch proton pump...
متن کاملOptical Pumping
T he rather odd term optical pumping means just what it says. In general “pumping” is a process of raising matter from lower to higher energy; for example, raising the potential energy of water hy moving it from an underground well to an elevated tank. In this article we shall he concerned w i t h the pumping of individual atoms from lower to higher states of internal energy. The word optical r...

Optical pumping uses light to affect the internal degrees of freedom of a sample of atoms in a vapor. These internal degrees of freedom are angular momentum states of the atomic ground state, which are populated when light is absorbed and emitted. This experiment reveals many phenomena of quantum mechanics including angular momentum selection rules, the density matrix, and resonance. Optical pu...

The primary role of the ZIP13 metal transporter in flies is to move iron ions out of cells, rather than moving zinc ions into cells, as is the case in human cells.
