Lectures 8-15 Flashcards
What part of the nervous system dominates the normal functioning of the lungs?
Parasympathetic
Persistent or unexpected coughing leads to what type of dysfx which complicates hemostasis?
Rib exhalation somatic rib dysfunctions
Pathophysiology of the pleura creates what structures?
Adhesions
What is dysfunctional about the receptors in the Hering-Breuer reflex?
They are unable to distinguish between fluid and air.
When the air sacs fill with fluid the Vagus. n sends a message to do what?
Decrease diaphragmatic excursion
What happens to the carotid body during this time?
It perceives the need for more O2 and sends signal to increase respiratory rate.
What is the ultimate result of the Hering-Breuer reflex?
Rapid, shallow breathing that can lead to loss of fluid.
What controls the sympathetics of the lungs?
T1-T6 (Parietal pleura may extend to T11)
What structures are stimulated by increased sympathetic tone and what does this lead to?
Stimulates bronchial glands, leading to increased numbers of Goblet cells and thick mucous secretions
Increased sympathetic tone does what to bronchiolar smooth muscle?
Relaxes it
What happens with prolonged sympathicotonia?
Vasoconstriction and hypoperfusion of the lung
What causes a Chapman point?
Increased sympathetic tone causes lymphatic stasis that is palpable as a tender myofascial, rubbery nodule. A primary visceral afferent produces a secondary myofascial tender point.

“The sympathetic nervous system is diffuse in distribution the and is the sole enervator of both the musculoskeletal and vasomotor systems. Therefore somatic dysfunction could impact on reflex patterns between both the musculoskeletal and autonomic nervous systems through the sympathetic intermediary, as well as the vasomotor system and could also become a common denominator in a wide variety of disease entities. The only way to alter sympathetic activity is osteopathic manipulative treatment.”
