18
Q

coronary sinus

A

enlarged venous return for most of the blood from the heart

19
Q

right atrioventricular orifice

A

large opening from the right atrium to the right ventricle

20
Q

intervenous tubercle

A

a transverse ridge of tissue between the caval openings

21
Q

fossa ovalis

A

slitlike depression caudal to the intervenous tubercle; is the foramen ovale in the fetus

22
Q

right auricle

A

blind, ear-shaped pouch of the right atrium that faces cranially and to the left

23
Q

endocardium

A

thin, glistening membrane that lines the inside of the heart

24
Q

crista terminalis

A

smooth-surfaced, thich portion of the heart muscle shaped like a semilunar crest at the entrance of the auricle

25
Q

parietal cusp

A

a wide but short flap that arises from the parietal margin of the orifice of the atrioventricular valve

26
Q

septal cusp

A

flap from the septal margin of the atrioventricular valve; nearly as wide as it was long

27
Q

chordae tendinae

A

attached to the septal wall by papillary muscles

28
Q

papillary muscles

A

conical muscular projections

29
Q

trabeculae incarnae

A

muscular irregularities of the interior of the ventricular walls

30
Q

trabecula septomarginalis

A

muscular strand that extends across the lumen of the ventricle from the spetal to parietal wall

31
Q

conus arteriosus

A

funnel-shaped; gives rise to the pulmonary trunk

32
Q

pulmonary valve

A

consists of 3 semilunar valves

33
Q

left atrium

A

situated on the left dorsocaudal part of the base of the heart dorsal to the left ventricle

34
Q

valve of the foramen ovale

A

thin, concave fold of tissue present on the cranial part of the interarterial septal wall; remnant of the passageway for blood from the right atrium to the left atrium in the fetus

35
Q

ligamentum arteriosum

A

fibrous connection between the pulmonary trunk and the aorta just caudal to the left subclavian artery

36
Q

aortic valve

A

consists of 3 semilunar cusps

37
Q

right coronary artery

A

leaves the right sinus of the aorta; encircles the right side of the heart in the coronary groove and often extends into the subsinuosal interventricular groove; sends many small and a few large descending branches over the surface of the right ventricle

38
Q

left coronary artery

A

twice as large as the right

39
Q

circumflex branch

A

part of the left coronary artery; extends caudally in the left part of the coronary sulcus and supplies the subsinuosal interventricular branch

40
Q

paraconal interventricular branch

A

part of the left coronary artery; obliquely crosses the auricular surface of the heart in the paraconal interventricular sulcus

41
Q

septal branch

A

part of the left coronary artery; courses into the interventricular septum

42
Q

coronary sinus

A

dilated terminal end of the great cardiac vein

43
Q

great cardiac vein

A

begins in the paraconal interventricular sulcus; returns blood supplied to the heart by the left cofronary artery
