The auricle or auricula is the visible part of the ear that is outside the head. It is also called the pinna (Latin for ' wing ' or ' fin ', pl.: pinnae), a term that is used more in zoology. The diagram shows the shape and location of most of these components:

Jan 22, 2025 · The auricle, also known as the pinna, is the external, visible part of the ear. It is composed primarily of elastic cartilage covered by skin, giving it a flexible yet durable structure. The auricle plays a role in shaping the external ear ’s contour and is involved in directing sound waves into the ear canal.

The auricle (or pinna, pinna of ear, auricle of ear, auricula, latin: auricula) is the external, visible component of the ear around the outer opening of the ear canal. The auricle is musculocutaneous tissues attached to the skull. The main function of the auricle is to collect, amplify and direct sound waves into the external auditory canal.

Nov 9, 2017 · The main difference between atrium and auricle is that atrium is a compartment of the heart whereas auricle is a small out-pouching of the atrium. Heart is composed of two atria and two ventricles. Atria are the upper compartments while ventricles are the lower compartments. Left atrium and right atrium are the two types of atria.

Oct 21, 2024 · Explore the anatomy and circulatory roles of heart auricles, including insights from recent research and comparative vertebrate studies. The auricles of the heart, small ear-like projections located on each atrium, contribute significantly to maintaining efficient blood flow and overall cardiovascular health.

Aug 16, 2020 · The auricle is a paired structure found on either side of the head. It functions to capture and direct sound waves towards the external acoustic meatus. It is a mostly cartilaginous structure, with the lobule being the only part not supported by cartilage. The cartilaginous part of the auricle forms an outer curvature, known as the helix.

auricle, in human anatomy, the visible portion of the external ear, and the point of difference between the human ear and that of other mammals. The auricle in humans is almost rudimentary and generally immobile and lies close to the side of the head. It is composed of a thin plate of yellow elastic cartilage covered by a tight-fitting skin.

2 days ago · Explore Innerbody's 3D anatomical model of the left auricle, a vital component of pumping blood within the heart. The left auricle, also known as the left atrial appendage (LAA), is a flap of heart wall on the anterior surface of the left atrium of the heart.

(also called auricula) an ear-shaped part or appendage, such as that occurring at the base of some leaves. The external structure of the ear.

Feb 12, 2025 · In humans the auricle is an almost rudimentary, usually immobile shell that lies close to the side of the head. It consists of a thin plate of yellow elastic cartilage covered by closely adherent skin. The cartilage is molded into clearly defined hollows, ridges, and furrows that form an irregular shallow funnel.
