To an insurance company, an insurable interest is the basic reason for issuing a legal insurance cover, to an insured (or beneficiary) it gives the legal right to enforce an insurance claim.
The change in membrane potential occurring in nerve, muscle, or other excitable tissue when excitation occurs. action potential. A momentary change in electrical potential on the surface of a neuron or muscle cell. Nerve impulses are action potentials.
Action Potential. The resting potential tells about what happens when a neuron is at rest. An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a spike or an impulse for the action potential.The action potential is an explosion of electrical activity that is created by a depolarizing current.This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about -55 mV a neuron will fire an action potential.he action potential is an explosion of electrical activity that is created by a depolarizing current.
