Calcium channel blockers are drugs used to treat people with high blood pressure. They mostly affect the smooth muscle in blood vessels. Why would blockage of calcium channels in these cells lead to a decrease in blood pressure. These drugs also can affect the myocardial muscle of the hear, where they decrease the strength of myocardial contraction. Explain why they have this effect. In some people, these drugs have a side effect of decreasing intestinal motility, but are not likely to have side effects of decreasing skeletal muscle contraction. Yet muscles in both places require calcium. Explain why side effects are more likely in intestine than in skeletal muscle.

People with diabetes can experience macrovascular complications. Explain (paragraph) 3 each of these macrovascular complications (easy and simple)
A patient came to a dental clinic with complaints of dry mouth and multiple dental caries lesions. In the course of collecting anamnesis, it was found that an allergic patient takes antihistamines that block the H2 histamine receptors of smooth muscle cells of the salivary glands. It is known that histamine is a mediator that stimulates the secretion of saliva. Explain the mechanism of action of these drugs if it is known that the next day after discontinuation of the drug, the patient's dryness disappeared. For this: а) write the classification of inhibitors according to the mechanism of action b) indicate what type of inhibitors the drugs are taken by the patient; confirm your conclusion in writing c) guess what structure this drug may have d) give a picture illustrating the action of this type of inhibitors.

An obese patient comes to the clinic complaining of swollen feet and ankles, fatigue, shortness of breath, and often feeling “spaced out.” She is a cashier in a grocery store, a job that requires her to stand all day. Outside of work, she engages in no physical activity. She confesses that, because of her weight, she finds even walking uncomfortable. Explain how the skeletal muscle pump might play a role in this patient’s signs and symptoms.An obese patient comes to the clinic complaining of swollen feet and ankles, fatigue, shortness of breath, and often feeling “spaced out.” She is a cashier in a grocery store, a job that requires her to stand all day.

The characteristics of vitamin P include the followings except: Select one: a. It increases the level of hyaluronidase which prevents the oxidation of ascorbic acid and adrenaline, as result it increases the strength of the blood vessels and capillaries b. It is related to flavonoids and phenolic compounds c. It decreases the capillary fragility and their permeability d. Vitamin P acts synergistically with ascorbic acid
You decide to do a series of experiments to determine where the toxin has its effect. You accomplish this by using a good, old- fashioned sciatic nerve/gastrocnemius preparation from a frog leg. This preparation dissects out the sciatic nerve (which contains the alpha-motor neuron fibers) still connected to the gastrocnemius (calf) muscle as shown below. The prep is placed in artificial ECF. Muscle Nerve Femur When you stimulate the nerve electrically, the muscle contracts. When you directly stimulate the muscle electrically, it also contracts. You then add the curare to the artificial ECF. Now, when you stimulate the nerve, the muscle no longer contracts. However, when you stimulate the muscle directly, it does contract. Based solely on these data, this means curare is potentially acting on: O Either the alpha motor neurons' ability to conduct action potentials, or the muscle's ability to conduct action potentials, but not on the neuromuscular junction. O Either the alpha motor…
