(29 cards)
where do the phrenic nerves lie
on top of the pericardium
where is the needle inserted in pericardiocentesis
via infrasternal angle and directed superoposteriorly
what is the infrasternal angle
lower border of costal cartilages
what is the transverse pericardial sinus
posterior to the ascending aorta and pulmonary trunk anterior to SVC
used by surgeons to idenfity and isolate great vessels
what makes up the base of the heart
L atrium
what makes up the R border of the heart
R atrium mainly
what makes up the inferior border of the heart
right ventricle
what groove indicates the surface marking for the tricuspid valve
coronary groove - the boundary between right atrium and right ventricle
what runs in the coronary groove
R coronary artery
coronary sinus
venous conduit in the AV groove posteriorly, drains deoxygenated blood from cardiac veins to the right atrium
oval fossa
the remnant of the foraman ovale found in the right atrium
crista terminalis
circular muscular ridge in the RA
what nerve begins at the ant scalene muscle
phrenic
what is the epicardium also called
the viscera serous pericardium
what is the intrapericardial pressure normally
around 0
what supplies the apex of the heart
LAD
what supplies the AVN
pos interventricular artery
what supplies the SAN
RCA
what are the coronary arteries embedded in
adipose tissue
what artery is most likely to be occluded
LAD (RCL)
which are the semilunar valves
aortic and pulmonary
decsribe the anatomy of the valves
have fibrous rings
have tendinous cords attached to papillary muscles to prevent prolapse during contraction
describe the anatomy of the aortic valve
has right, left and posterior cups
and spaces between the cups called sinuses
what do the aortic and pulmonary valves both develop from
truncus arteriosus
