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.
Receptor potential is the same as resting membrane potential. For an impulse to take place there must be a state of readiness in the neuron, so the resting membrane potential is an electrical charge brought about by the difference between positive and negative ions outside and inside the cell, if the ions were distributed equally inside and outside there would be no charge and no potential.
