Why is it only possible to induce an extrasystole during relaxation? Because cardiac muscle is able to depolarize after repolarization takes place. 4) Explain why wave summation and tetanus are not possible in cardiac muscle tissue. How well did the results compare to your prediction? Cells do not show tetanus or summation because cardiac cells have both long action potentials and long twitches. Activity 2 1) Explain the effect that extreme vagus nerve stimulation had on the heart. How well

Why would the closure of a potassium channel in the presynaptic axon terminal change the amount of Ca2︎ entering and change the amount of neurotransmitter released? Serotonin(5-HT) receptor on the sensory axon terminals is a G-protein-coupled metabotropic receptor. Stimulation of this receptor leads to the production of intracellular second messengers‚ cAMP‚ which

Skeletal Muscle Fiber: Skeletal muscle cells that are composed of hundreds to thousands of individual cells that produce muscle tension. These fibers are what move our bodies and generate muscle tension/force that enables us to have manual dexterity. Motor unit: consists of one motor neuron and all of the skeletal muscle fibers that
