Left auricle - Auricula sinistra

Description

The auricula (auricula sinistra; left auricular appendix) is somewhat constricted at its junction with the principal cavity; it is longer, narrower, and more curved than that of the right side, and its margins are more deeply indented. It is directed forward and toward the right and overlaps the root of the pulmonary artery.
