A 22-year-old student stands up after studying at her desk all morning. As soon as she stands, she becomes light headed and has to hold the back of her chair because she feels as though she may faint. Within a few seconds, she feels fine and walks to the water fountain. What anatomic structure was responsible for measuring her drop in blood pressure? Carotid body Carotid sinus Cervical plexus Choroid plexus Ciliary ganglion Submandibular ganglion

Step 1
The question describes a scenario where a person experiences a temporary drop in blood pressure upon standing (orthostatic hypotension) and asks which anatomical structure is responsible for *measuring* this drop. This points to a baroreceptor function. Show more…

A patient faints if he gets up out of bed too quickly. Which one of the following events would most likely account for such fainting? A) Reduced baroreflex function. B) Exaggerated increase in renal sympathetic nerve activity. C) A baroreflex-mediated reduction in heart rate. D) Increased blood pressure. E) Activation of the Cushing response. 2. Mean arterial pressure readings over 3 months are between 95 and 105 mmHg for patient X and between 140 and 150 mmHg for patient Y. What is the effect of a rapid decrease in carotid sinus pressure? A) Increase in both sympathetic and parasympathetic nerve activity only in patient X. B) Increase in sympathetic and decrease parasympathetic nerve activity only in patient X. C) Increase in firing in the baroreceptor afferents about equally in both patients. D) Increase in plasma renin activity only in patient Y. E) Decrease in parasympathetic nerve activity about equally in both patients.

Case 11 Responses to Changes in Posture Case Joslin Chambers is a 27-year-old assistant manager at a discount department store. One morning, she awakened from a deep sleep and realized that she was more than an hour late for work. She panicked, momentarily regretting her late-night socializing, and then jumped out of bed. Briefly, she felt light-headed and thought she might faint. She had the sensation that her heart was "racing." Had she not been so late for work, she would have returned to bed. As she walked toward the bathroom, she noticed that her light-headedness dissipated. The rest of her day was uneventful. QUESTIONS When Joslin moved rapidly from a supine (lying) position to a standing position, there was a brief, initial decrease in arterial pressure that caused her light-headedness. Describe the sequence of events that produced this transient fall in arterial pressure. Joslin's light-headedness was transient because a reflex was initiated that rapidly restored arterial pressure to normal. Describe the specific effects of this reflex on heart rate, myocardial contractility, total peripheral resistance (TPR), and capacitance of the veins. What receptors are involved in each of these responses? How does each component of the reflex (e.g., the effect on heart rate) help to restore arterial pressure? (Hint: It may help to write the equation that relates arterial pressure, cardiac output, and TPR.) In addition to the reflex correction of blood pressure, the fact that Joslin walked to the bathroom helped return her arterial pressure to normal. How did walking help?
