The permeability to ions of the neural lamella and the extracellular spaces in the C.N.S. of Anodonta cygnea.
Rapid axonal depolarization follows the elevation of [K+]o in the Ringer bathing the surfaces of the connectives of both intact and desheathed cerebrovisceral connectives of Anodonta cygnea. Potassium movements between the blood or medium bathing the surface of the connectives and the axonal membranes can be accounted for in terms of a first-order diffusion process. No visible structural barrie...
متن کاملThe ionic basis of axonal conduction in the central nervous system of Anodonta cygnea (Mollusca: eulamellibranchia).
The bivalve mollusc Anodonta cygnea appears to be unique in possessing the most dilute body fluids so far described in the Animal Kingdom. The osmotic concentration of the blood of this species has been found to amount to only about 44-0 m-osmole, with a sodium concentration which averages 15-6 mM/kg. (Potts, 1954). It is difficult to explain the ionic basis of electrical activity of excitable ...
متن کاملStudy of Linear Alkyl Benzene (LABs) as molecular marker of sewage pollution in Bivalves Mollusk “AnodontaCygnea” in Anzali lagoon
Tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. In this research, in four stations of Anzali Lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured and evaluated with molecular indicator Lin...
متن کاملThe ionic basis of the fast action potentials in the isolated cerebro-visceral connective of Anodonta cygnea.
Previous communications from this laboratory have been concerned with an attempt to elucidate the ionic basis of action potential production in the central nervous system of Anodonta cygnea. This eulamellibranch mollusc was chosen for these studies as it appears to be the possessor of the most dilute blood so far described in the Animal Kingdom (Potts, 1954) and, for this reason, presents some ...
متن کاملAssessment of Anodonta cygnea as a Biomonitor Agent for Copper and Zinc in Anzali Wetland, Iran
Background: Anzali wetland has been subjected to high levels of pollution due to contamination from several industrial sites in addition to agricultural chemicals. Mussels have been widely used for monitoring pollution in aquatic ecosystems, because they, as filter feeders, bioaccumulate pollutants. Therefore we decided to evaluate Anodonta cygnea for its application as a bio-monitor for copp...
