EXPERT RATIONALES GRADED A+
⩥ Incidence. Answer: The number of new cases of a disease or condition
in a specific population or group.
⩥ Prevalence. Answer: The number of cases of a disease present in a
specified population at a given time.
⩥ Morbidity. Answer: The state of being diseased; the number of sick
persons or cases of a disease in a specific population.
⩥ Mortality. Answer: The death rate; the ratio of the number of deaths
from a given disease to the total number of cases of that disease.
⩥ Apex. Answer: The pointed portion of the heart, rests on the
diaphragm.
⩥ Base. Answer: The top portion of the heart directed upward to the
right.
,⩥ Tricuspid Valve. Answer: Separates the right atrium and the right
ventricle.
⩥ Pulmonary Valve. Answer: Between the right ventricle and pulmonary
artery, prevents backflow of blood into the right ventricle.
⩥ Mitral Valve. Answer: Separates the left atrium and left ventricle.
⩥ Aortic Valve. Answer: One-way structure with 3 cusps that prevents
backflow of blood from the aorta to the left ventricle.
⩥ Stenosis. Answer: The area of a passage or orifice that has been
constricted or narrowed.
⩥ Insufficiency. Answer: The condition of being inadequate for a given
purpose.
⩥ Regurgitation. Answer: The backward flow of blood through a
defective heart valve.
⩥ Chordae Tendineae. Answer: Fibrous strands which extend upward
from the papillary muscles and attach to the edges of the leaflets of the
AV valves.
, ⩥ Papillary Muscles. Answer: Conical muscular projections from the
walls of the cardiac ventricles attached to the cusps of the AV valves by
the chordae tendineae.
⩥ Mitral Annulus. Answer: The circular band surrounding the opening
of the mitral valve.
⩥ Coronary Arteries. Answer: Either of 2 arteries (one on the right and
one on the left) that arise from the aorta immediately above the
semilunar valves and supply blood to the tissues of the heart.
⩥ Left Main Coronary Artery (LCA). Answer: The initial portion of the
coronary artery system that supplies blood to the anterior/left side of the
heart.
⩥ LAD. Answer: Travels anteriorly down the interventricular septum
towards the apex.
⩥ Circumflex. Answer: Travels along the AV groove around the mitral
valve annulus from the anterior to posterior branches that feed the lateral
side of the left ventricle.
⩥ Right Main Coronary Artery (RCA). Answer: Usually arises from the
right coronary sinus off the aorta; supplies blood to the conducting
tissues and the right ventricle.
