Function of baroreceptors in controlling blood pressure
Question
Answer
True or False: When blood pressure rises, baroreceptors send barrages of nerve impulses to the brain.
True
True or False: When blood pressure rises, impulses sent by baroreceptors to the brain inhibit the vasomotor center.
True
True or False: When blood pressure rises, the vasomotor center decreases the number of impulses transmitted to the heart and blood vessels.
True
True or False: When blood pressure rises, the lack of impulses sent from the the vasomotor center to the heart causes diminished pumping activity by the heart and dilation of peripheral blood vessels.
True
True or False: The baroreceptor system controls homeostasis of blood pressure.
True
True or False: When blood pressure falls, baroreceptors signaling frequency decreases.
True
True or False: When blood pressure falls, there is increased signaling from the vasomotor center to the blood vessels.
True
True or False: When blood pressure falls, there is constriction of vascular smooth muscle.
True
True or False: Rate of signaling by baroreceptors is proportional to blood pressure.
True
True or False: When blood pressure falls, the stretch receptors of the baroreceptors relax.
True
True or False: When blood pressure falls, the vasomotor center becomes more active.
True
True or False: When blood pressure falls, you get vasoconstriction and increased heart pumping.
True
True or False: When blood pressure rises, baroreceptor signaling decreases.
False
True or False: When blood pressure rises, signals sent by the barorecptors activates the vasomotor center.
False
True or False: When blood pressure rises, the vasomotor center increases the number of impulses transmitted to the heart and blood vessels.
False
True or False: When blood pressure rises, the increase of impulses causes increased pumping activity by the heart and vasoconstriction of the peripheral blood vessels.
False
True or False: When blood pressure rises, the vasoconstriction of the blood vessels decreases flow of blood through the vessels and increases arterial pressure.
False
True or False: When blood pressure rises the baroreceptors are stimulated by the stretch of the arterial wall.
True
True or False: When blood pressure falls, the vasomotor center becomes less active.
False
True or False: When blood pressure falls, baroreceptors signaling increases.
False
True or False: When blood pressure falls the vasomotor center decreases number of impulses to the heart and blood vessels.
False
True or False: When blood pressure falls, the decreased impulses from the vasomotor center increases the pumping activity of the heart and constriction of blood vessels.
False
True or False: When blood pressure falls, there is vasodilation of vascular smooth muscle.
False
True or False: When blood pressure falls, baroreceptors signaling frequency increase.
False
True or False: When blood pressure rises, baroreceptors signaling frequency falls.
False
True or False: Blood pressure and baroreceptor signaling are inversely proportional.
False
True or False: Blood pressure and baroreceptor signaling are directly proportional.
True
True or False: When blood pressure rises, the stretch receptors of the baroreceptors relax.
False
True or False: When blood pressure falls the baroreceptors are stimulated by the stretch of the arterial wall.
