The resting membrane potential of a typical animal cell arises predominantly through the action of the Na-K pump, which in each cycle transfers 3 Na ions out of the cell and 2 K into the cell, leaving an excess of negative charges inside the cell.? 正确错误 相关知识点: 试题来源: 解...
Bimodal oscillations (<1 Hz) of the cell resting membrane potential, typically cortical or thalamic neurons, between hyperpolarized (DOWN) and depolarized (UP) states. Thalamus A symmetrical collection of nuclei in the diencephalon, with functions including sensory relaying to neocortex, alertness, ...
Intracellular recordings of membrane potential, input resistance and time constant have been made in vitro from the follicular cells of the rat, rabbit and guinea-pig thyroid glands using glass microelectrodes. The passive permeability properties of these cells have been investigated by altering the co...

Fill in the blank: Specialized protein molecules that help control cell activity are ___. Fill in the blank: Cells that secrete mucin are called ___. Fill in the blank: Depolarization is a _ in resting membrane potential caused by _. In phagocytosis...
The dependence of ionic currents on membrane potential is used to introduce slope and chord conductance, and this is used to derive the chord conductance equation for resting membrane potential. This chapter ends with the conventions for potential and current flow....
Changes in the plasma membrane potential of two histanmine-releasing cells, rat peritoneal mast cells and basophilic leukemia cells 2H3 (RBL 2H3), were recorded with the potential-sensitive dye bis-oxonol. For mast cells, the presence of ouabain or the absence of K + increased the fluorescen...
of the membrane potential is allowed to be the resting potential or should be lower than this level15; however, the theoretical background behind this concept was lacking, and no study has analyzed the impact when the lower bound of the membrane potential is limited to the resting potential. ...
