OMM cardio Flashcards
75% of parasympathetic influence on heart is from?
CN 10
parasympathetics involved
Cranial: CN 3,7,9,10
sacral: S2-S4
result of parasympath innervation to CV system
- heart decr rate & contractility
2. coronary arteries constrict
is there any effect of parasymp activation on blood vessels?
NO
sympathetic ganglia involved in CV
cervical ganglia
lumbar splanchnic nerves
result of sympathetic innervation to CV system?
- blood vessels constrict (except skeletal)
- heart increases rate & contractility
- coronary arteries dilate
things to check for CV?
inlet, thoracoabdominal, inominates, sacrum
Found in the myocardium and vasculature and relay information of pressure and stretch back to CNS via visceral afferents.
mechanoreceptors
Move along the same afferent pathways and terminate on interneurons that also process somatic nociceptive information.
chemoreceptors
Stimulation of chemo- and mechanoreceptors located in the thoracic viscera results in what type of pain?
visceral pain
Pain fibers are found in skin, subcutaneous tissue, muscles, and bones in the chest wall.
somatic pain
somato-visceral: heart & neck
C6
somato-visceral: heart, lower neck, arm, posterior cranial arteries
C7
viscero-somatic sympathetics: head & neck
T1-4
viscero-somatic sympathetics: lungs
T1-6
viscero-somatic sympathetics: stomach
T5-9
what sympath innervates the deep cardiac plexus & AV nodes?
left
what sympath innervates he deep cardiac plexus, right heart, SA node?
right
overstimulation of left sympathetics?
ectopic foci & v fib
overstimulation of the right sympathetics?
supraventricular tachyarrhytmias
hyperactivity of left vagus?
AV block
hyperactivity of right vagus?
sinus bradycardia-arrhythmia
drainage from heart & lungs is carried by which lymphatics?
left thoracic duct
what is the chief factors for lymphatic return?
diaphragm
