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.
Do Chapman points radiate?
No
How do you manipulate a Chapman point?
With mild-moderate pressure in small circles; do this until modularity and tenderness dissipates
Where is the anterior Chapman point for the Bronchus?
2nd intercostal space near the sternum
Where is the anterior Chapman point for the Upper Lung?
3rd intercostal space near the sternum
Where is the anterior Chapman point for the Lower Lung?
4th intercostal space near the sternum
Where is the posterior Chapman point for the Bronchus?
In the soft tissue between spinous process of T2 and transverse process of T2
Where is the posterior Chapman point for the Upper Lung?
In the soft tissue between spinous process of T3 and transverse process of T4
Where is the posterior Chapman point for the Lower Lung?
In the soft tissue between spinous process of T4 and transverse process of T5
What is the parasympathetic nerve of the lung?
Vagus (CN X)
What do CN IX/X, and the carotid body control?
BP, CO2, and O2 regulation
What effect do the parasympathetics have on the bronchial cells?
Inhibition of bronchial cells decreases the number of Goblet cells and leads thinning of mucous
How do parasympathetics effect the bronchiolar smooth muscle?
Cause constriction
Typical ribs have _____ articulation with the transverse process but have ______ articulation(s) some the same vertebrae
