If symptoms of exocrine pancreatic insufficiency are apparent, a number of pancreatic function tests can be done. A serum sample that measures the amount of the chemical trypsinogen (TLI) released into the blood from the pancreas should reveal problems in the pancreas. A dog with EPI will have reduced amounts of TLI.
Neuron Resting Potential-Resting Membrane Potential of the neuron. The voltage difference between the intracellular space and the extracellular space when a neuron is in its non-activated state, is the cells resting potential, which is around -- 70 mV. The resting potential is the electrical charge the cell has when it is resting and when it is not stimulated by any open ion channels.
Check Point g The Resting Membrane Potential is always negative (-70mV) 1  K+ pass easily into the cell. 2  Cl- and Na+ have a more difficult time crossing. 3  Negatively charged protein molecules inside the neurone cannot pass the membrane. 4  The Na+K+ATPase pump uses energy to move 3Na+ out for every 2K+ into neuron.
