Week 3 Flashcards
interventricular grooves
between
ventricles
crista terminalis
terminal crest, a crest of tissue separating the rough and smooth
portions of the right atrium
musculi pectinati
pectinate muscles, the ridges of the rough portion of the atrium
coronary sinus
drains blood from the coronary circulation back into the right
atrium.
where is the fossa ovalis
the oval depression in the thin interatrial septum
what can i find in the right atrium
crista terminalis
musculi pectinati
coronary sinus
fossa ovalis
what can i find in the right ventricle
tricuspid valve papillary muscles of the tricuspid valve chorda tendineae trabeculae carnae pulmonary valve outflow tract of the right ventricle
what is the pulmonary valve
a semilunar valve
rough part
trabeculae carnae
smooth part
infundibulum
how many cusps in the tricuspid valve
three
how many cusps in the mitral valve.
two
how can i tell its the left auricle
its muscular ridges
what is above the three aortic valuve cusps?
the aortic sinuses
where does the right coronary artery arise from
the anterior aortic sinus
where does the left coronary artery arise from
the left posterior aortic sinus.
what are the atrioventricular sulci
grooves between the atria and ventricles
where is the heart
in the mid thorax with 2/3 to the left of the sternum and 1/3 to the right.
where are the auscultatory areas on the skeleton
tricuspid area
pulmonary area
mitral area
aortic area
tricuspid area
located at the lower left sternal border
pulmonary area
Located at the left second intercostal space adjacent to the left
sternal border.
mitral area
located at the left fifth intercostal space in the left midclavicular line
aortic area
Located at the right second intercostal space adjacent to the right sternal border.
The visceral pericardium is known as
the epicardium.
