(Hint: relate your response to the refractory period of the cardiac action potential) How well did the results compare with your prediction? The threshold doesn’t change because after the voltage was simulated the cardiac muscle cells Ca channels opened. You cannot open them anymore or reopen them before depolarization. This is due to the refractory period. 3) Why is it only possible to induce an extrasystole during relaxation? Because cardiac muscle is able to depolarize after repolarization takes

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

Therapeutic Hypothermia for Cardiac Arrest Jaime Bromley Jefferson College of Health Sciences Hypothermia is a decrease in the core temperature below 35 degrees Celsius or 95 degrees Fahrenheit. There are various medical uses for hypothermia. Therapeutic hypothermia is the only proven effective treatment for post cardiac arrest patients. Hypothermia decreases the amount of cerebral oxygen needed and also lessens the inflammatory response post cardiac arrest. This prevents brain damage and death

saline on cardiac output? HYPOTHESIS: Cardiac output is higher in a hot saline and low in cold saline temperature parameters. Educated Guess Answer: Phenomenally cardiac output is supposed to rise in hot saline conditions and drastically go down in cold saline conditions.

After this point‚ no additional voltage can cause the channels to open more‚ or again‚ prior to depolarization. 3.

goes into cardiac arrest‚ almost drowns or suddenly stops breathing. Anyone with a small child at home could benefit from knowing CPR. Small children can easily choke on a toy‚ food or even come close to drowning in the bath tub or any pool of water. Everyone in a household where there are adults in the home that are at risk of going into cardiac arrest‚ should take a training course on CPR because cardiac arrest victims that receive CPR have a better chance of survival.
