What is the difference in effect of alpha 1 adrenergic receptors and beta 2 adrenergic receptors on smooth muscle in the blood vessel? How does that affect vasomotion and blood flow?
Step by step
Solved in 2 steps
- Following a large increase in sympathetic output from the vasomotor center, what tissues will get less blood (increased resistance, reduced flow), and which ones will continue to get plenty of flow? How is sympathetic control of skeletal muscle arterioles different from other vascular beds?Why, in physiological terms, does systolic blood pressure increase from rest to exercise and why would diastolic blood pressure remain relatively constant from rest to exercise? Discuss the roles of the nervous system, endocrine, and baroreceptorsWhy is it possible for acetylcholine to actually cause an increase in stroke volume, even though increased parasympathetic activity causes an overall decrease in cardiac output?
- What is the cause of reflex tachycardia?Knowing that a patient with chronic heart failure is using digoxin (digitalis) for more than 1 year, what effect has this treatment on the distribution of ions across the membrane of cardiac muscle cells? What is effect will be of digitalis on cardiac contractility? What is an inotropic effect? How does digitalis help to treat patients with heart failure?Epinephrine is released during vigorous exercise. How would epinephrine cause vasoconstriction in the digestive organs but vasodilation in the heart?
- How does the barorecptor reflex explain the decrease in heart rate during carotid sinus massage?Where are the cardiovascular control centers located? What 2 branched of the ANS are involved? Where do these branches insert on the heart to modulate heart rate? How does each branch modulate heart rate (include neurotransmitters, increased ion movement, and resulting action potentials in your answer)?Why is the rate of cardiac muscle relaxation faster when a positive inotropic agent is present?
- What effect would stimulating the acetylcholine receptors of the heart have on cardiac output?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.Fill in the following blanks (a - f) regarding the Baroreceptor Reflex Control: The baroreceptor reflex control is a negative feedback loop. If the patient is hypotensive, they are experiencing a decrease in blood pressure detected by (a.)_ located in the aortic and carotid bodies. The afferent pathways include the (b.)_ nerve and the (c.)__ nerve. These synapse at the cardioregulatory and vasomotor integration centers located in the (d.)_ These centers will cause the heart rate to (e.)(increase/decrease) and blood vessels to (f.) (vasodilate/vasocontrict). For the toolbar press ALT+510 (BC) or ALTHEN±+510/Mad
