AURICLES Meaning and
Definition
-
Auricles refer to the specific anatomical structures found in the heart and ears. In the realm of cardiac anatomy, the auricles are two small, conical structures that are present on the upper surface of the atria. These structures, also known as auricular appendages or atrial appendages, resemble small ear-like projections that extend from the main body of the atria. The human heart consists of two auricles – the left auricle and the right auricle. The purpose of the auricles is to help increase the capacity and efficiency of the atria by providing them with more space for blood collection and storage. The auricles play a crucial role in the contraction and expansion of the atria, aiding in the proper circulation of blood within the heart.
In the field of otology, the term auricles is used to describe the external part of the ear. Commonly known as the pinna, the auricles are the visible, outermost part of the ear in humans and many animals. These structures consist of cartilage covered by skin and are responsible for collecting sound waves and directing them into the ear canal. The auricles, along with the ear canal, play a crucial role in the process of sound localization and transmission, aiding in the reception and interpretation of auditory stimuli.
