2017 Flashcards
spirometry of fibrosing alveolitis
FEV1 reduced, FVC reduced FEV1/FVC normal and PEF normal
what kind of lung disease is fibrosing alveolitis
restrictive
what acts on the post junctional muscarinic end plate receptor on airway smooth muscle to mediate constriction
acetylcholine
what acts on the membrane bound beta 2 adrenoceptor on airway smooth muscle to mediate relaxation
adrenaline
what is a metabolite of the arachadonic acid pathway and released from eosinophils and mast cells and mediates airway smooth muscle constriction increased vascular permeability and mucous secretion
leukotriene D4
what medications improve the survival in chronic congestive heart failure
ACEi and beta blocker s
what treats ascites quickly
paracentesis
what improves the itch associated with biliary cirrhosis
uresodeoxycholic acid
spirometry of copd
everything reduced
what nerve carries somatic sensory nerve fibres from the CNS to allow movement of the facial skin
V - trigeminal
what cranial nerve innervates the muscles that cause adduction of the vocal cords
X - vagus
at risk drinking for en is the regular consumption of
more than 3 units per day
how many units in a pink
2
chronic agonist induced stimulation of airway beta 2 receptors results in
beta 2 receptor down regulation and reduced receptor coupling to G protein - adenylyl cyclase
sensitisation of airway smooth muscle by asthmatic inflammatory mediators resullts in
reduced airway hyper reactivity on bronchial challenge testing
what is the venous angle between
the subclavian vein and the internal jugular vein
what drains into the right atrium
IVC
what do intercostal veins from the anterior aspect of the intercostal spaces drain into
internal thoracic vein
what do intercostal veins from the posterior aspect of the intercostal spaces drain into
azygous veins
what antimicrobial protein is secreted by epithelial cells at mucous surfaces
defensin
which is associated with the epiblast layer of the bilaminar embryo
amniotic cavity
what is associated with the hypoblast
yolk sac
