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.
The action potential occurs as a result of a stimulus to the neuron This means that some event (a stimulus) causes the resting potential to move toward 0 mV When a neuron is not sending a signal, it is at rest..hen a neuron is at rest, the inside of the neuron is negative relative to the outside Action potentials are caused by an exchange of ions across the neuron membrane. A stimulus first causes sodium channels to open.
