Question
Chapter 23.4, Problem 1AWYK
Summary Introduction
To explain:
The autonomic respiratory rhythms and the effecting organs of the nervous system. Highlight the role of the effector organs that facilitate ventilation in the lungs.
Introduction:
Respiratory rhythms are involuntary in action. The rhythms make sure the continuous exchange of gases in the body alongside the oxidation of glucose or food. Autonomous refers to the processes which occur on their own and are not consciously controlled.

Which one of the following statements about the afferent components of the respiratory control system is INCORRECT?
Select one:
a.
In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent.
b.
In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres.
c.
Chemoreceptor cells can be found in the carotid body.
d.
The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.
which of the following would not be a characteristic of respiratory responses to parasympathetic dominance?
a. brochiodialation
b. increased bronchial tone
c. decreased breathing depth
d. reduced breathing rate
Neural output from the brain stem regulated breathing including respiratory rate and depth. In a patient with damage to the medulla oblongata and subsequently to the phrenic nerve, which of the following would be true?
a. the diaphragm may not be able to contract, resulting in respiratory arrest
b. the respiratory rate and depth would increase as signals from the pons would increase
c. the diaphragm will begin to contract on its own via autorhythmic cells

Physical examination revealed that the patient had a mean heart rate of 55 beats/min. His physician noted that the patient's cardiac rhythm varied substantially with the phases of respiration; the heart rate increased during inspiration and decreased during expiration. QUESTION: What changes in cardiac sympathetic and parasympathetic activity take place during the respiratory cycle? QUESTION: Are the respiratory fluctuations in heart rate produced by the rhythmic changes in sympathetic activity, in parasympathetic activity, or both? The physician diagnosed this patient's headaches as migraine. He advised the patient to take propranolol, a ß-adrenergic receptor antagonist, to relieve the headaches. The physician noted that after the patient had taken the propranolol, the mean heart rate diminished very slightly, and the respiratory fluctuations in heart rate were not…arrow_forward
- You have both peripheral chemoreceptors (aortic arch and carotid bodies) and central chemoreceptors (medulla). You were informed earlier that the central chemoreceptors are the primary sensors for blood CO2. Both sets of chemoreceptors detect the concentration of H+ in blood or cerebral spinal fluid (CSF).
