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.
In most resting neurons, the potential difference across the membrane is about 30303030 to 90909090 mV\text{mV}mVm, V (a mV\text{mV}mVm, V is 1/10001/10001/10001, slash, 1000 of a volt), with the inside of the cell more negative than the outside.
