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.
What are the steps in muscle contraction. 1. Efferent motor cortex axons synapse on the spinal cord and generate an action potential in the Î±-motor neuron. 2. The action potential travels to the axon terminal, releasing acetylcholine into the synaptic cleft.3.Acetylcholine binds a receptor on the skeletal muscle cell and generates an action potential, increasing Ca++ release from the sarcoplasmic reticulum.4. Ca++ initiates contraction, resulting in shortening of the muscle cell and, consequently, movement.he action potential travels to the axon terminal, releasing acetylcholine into the synaptic cleft. 3. Acetylcholine binds a receptor on the skeletal muscle cell and generates an action potential, increasing Ca++ release from the sarcoplasmic reticulum.
