What is "auricle"?
The auricle refers to the small, muscular pouch-like structure located on the superior surface of each atrium. It is commonly known as the atrial appendage or atrial auricle.

What is "auricle"?
The auricle, also known as the external ear or pinna, is the visible part of the ear that protrudes from the side of the head. It is composed of cartilage and is responsible for collecting sound waves and directing them into the ear canal. The auricle plays a crucial role in the localization and amplification of sound, allowing us to perceive and interpret the auditory information in our environment.
