QUESTION: 4. Discuss major causes of heart valvular defects
Below are drawings of three different action potentials. Two of these occur in the heart, and one occurs in skeletal muscle. Which one comes from a contractile cardiac muscle cell? A skeletal muscle cell? A cardiac pacemaker cell? For each one, state which ion is responsible for the depolarization phase and which ion is responsible for the repolarization phase.

One medication used in treating COVID patients who have been placed on mechanical ventilators is Vecuronium, an acetylchone antagonist at skeletal muscle neuromuscular junctions (NMJs). Vecuronium is used on sedated patients to provide skeletal muscle paralysis, which allows the mechanical ventilator to work without the patient’s diaphragm contracting on its own and potentially working against the ventilator. Please do two things: Explain the way in which the NMJ would cause skeletal muscle contraction in the absence of the medication. Start by describing the mechanism of neurotransmitter release in the presynaptic cell and stop when the first crossbridge cycle is complete. Explain the specific way in which the medication impacts the functionality of the NMJ and skeletal muscle contraction. Please make sure to include 1.NT release 2.AP 3.Calcium release/binding 4.Crossbridge cycling 5.Med impact
A large grasshopper and a small mouse may be similar in size. However, the total length of blood vessels is much greater in the mouse, and the mouse’s heart pumps at much higher pressure than the grasshopper’s hearts. Which statement is most useful for explaining these observations?

30. Early defibrillation is critical for individuals with sudden cardiac arrest for the following reasons EXCEPT: O A common initial rhythm in out-of-hospital witnessed sudden cardiac arrest is ventricular fibrillation (VF). The most effective treatment for ventricular fibrillation (VF) is electrical defibrillation. O Individuals in asystole respond well to early defibrillation. O The probability of successful defibrillation decreases quickly over time.

Question 33 2 Commen Which of the following statements about blood vessel compliance is true? O A. Blood vessel compliance is defined as the ability of a blood vessel to contract and relax in response to changes in sympathetic stimulation. O B. Compliance is defined as the change in volume divided by the change in pressure, for a particular blood vessel. O C. Blood vessel compliance increases with age due to changes in the structure and composition of the vessel wall. OD. Increased blood vessel compliance leads to an increase in systolic blood pressure. O E. All of the following are true
