Anatomy Flashcards
epicardium =
visceral serous pericardium
where is needle for a pericardiocentesis placed
infrasternal/subcostal angle
transverse pericardial sinus =
posterior to aorta and pulmonary trunk
used to isolate great vessels to start cardiopulmonary bypass
Right border of the heart =
right atrium
Left border of the heart =
left ventricle
base/posterior of heart =
mainly L atrium
diaphragmatic surface of the heart =
R ventricle
coronary groove/sulcus=
boundary of R atrium and ventricle - contains RCA
Anterior interventricular groove contains
LAD
Posterior interventricular groove contains
post. interventricular vein
Lies in the posterior atrioventricular groove and drains cardiac veins to RIGHT atrium
coronary sinus
L mainstem artery lies in ____
branches =
L atrioventricular groove
circumflex
marginal
LAD->lateral/diagonal branch
RCA lies in ___
branches =
R atrioventricular groove
R marginal
Posterior interventricular
pulmonary valve =
anterior, left and right
semilunar
aortic valve =
posterior, left and right cusps
semilunar
coronary arteries lie just superior
tricuspid valve =
anterior, posterior and septal cusps
moderator band/septomarginal trabecula =
muscle in RV carries part of RBB to anterior papillary muscle - facilitates conduction and allows coordinated papillary contraction so valves shut
Carries conduction from R -> L atrium
Bachmann’s bundle
__ internodal tracts carry signal from SAN to AVN =
3 - anterior, middle (of Wenchenbach), posterior (of Thorel)
Symp, Para and visceral afferents reach heart via ___
cardiac plexus behind the aortic arch
Post-synaptic nt in sympathetic system
noradrenaline
Parasympathetic flow to the heart =
CNX
Nerve endings for stretch and chemicals in blood are located at:
inner aortic arch PT around SAN ventricles papillary muscles vena cava
Pain sensations from different soma reach consciousness at different points on the ____
band of post central gyrus of parietal lobe
(after central sulcus between frontal and parietal lobes
