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.
â¢ a wave of electricity that travels down the axon of neuron â¢ from the cell body to the axon terminals This wave of electricity is actually a brief change in the resting membrane potential of the neuron â¢ from -70mv to +35mv Then the membrane returns to its resting potential of -70mv. Briefly opening more membrane gates for Na+ and then for K+ â¢ Thus making the neuron cell membrane o More permeable first to Na+ o Then to K+ â¢ This causes a change in the numbers of plus charges inside and outside the cell membrane o Changing the cell membrane potential.
