Q

Tuberculum intervenosum

A

A transverse ridge of tissue between the two caval openings of the interatrial septum. It diverts the inflowing blood from the two caval veins toward the Ostrium atrioventricularie dextrum.

Q

Fossa Ovalis and Foramen Ovale

A

A depression caudal to the intervenous tubercle. It is the remnant opening of the foramen ovale, which in fetus allows blood to pass from the right to the left atrium.

Q

Pectinate Muscles

A

Interlacing muscular bands which strengthen the interior wall of the right auricle. They radiate to the auricle from the crista terminalis. They are also located on the lateral wall of the atrium proper.

Q

Crista Terminalis

A

A smooth-surfaced, thick portion of heart muscle shaped like a semi-lunar crest at the entrance to the auricle. Pectinate muscles radiate from this crest to the auricle.
