anatomy 1 Flashcards
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
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
describe the layers surrounding the heart
what is found between the ventricles
interventricular septum
what is found in the left arterioventricular groove
LCA
what is the anterior interventricular groove
marks the boundary between the 2 ventricles and where the LAD lies
