After her workout, Arlene lies down on a mat to stretch out her leg muscles. She stands up suddenly after stretching and feels a bit light-headed. However, the lightheaded feeling passes quickly. What physiologic process occurred that resulted in the passing of her light-headed feeling? a. The aortic bodies detected an increase in blood pressure in the head and initiated a chemoreceptor reflex that decreased blood pressure. b. The carotid bodies detected low CO2 and high O2 levels from exercising and stimulated the vasomotor center to vasoconstrict the vessels of the head and neck. c. Only α receptors in the head and neck initially were being stimulated, resulting in the light-headed feeling. d. The baroreceptors within the carotid detected decreased stretch in the carotid vessel wall and initiated an autonomic reflex to increase blood flow to the head and neck.

If blood pressure was to drop, how is the signal transmitted to the central nervous system? a) The baroreceptors decrease the generation of action potentials below their normal level. b) The glassopharyngeal nerve increases the transmission of action potentials, while the vagus nerve does not. c) The baroreceptors increases the generation of action potentials past their normal level. d) The glassopharyngeal nerve decreases the transmission of action potentials, while the vagus nerve does not.

What is true about carotid arteries? a. Carotid arteries carry oxygenated blood to the brain b. Carotid arteries carry oxygenated blood away from the brain c. Carotid arteries carry deoxygenated blood to the brain d. Carotid arteries deoxygenated blood away from the brain
