AURICULARIS MAGNUS Meaning and
Definition
-
The term "Auricularis Magnus" refers to a specific muscle located in the human body. This muscle, also known as the "Greater Auricular Muscle," is situated in the head and neck region. It is one of the three muscles that make up the auricular muscles group, alongside the anterior and posterior auricular muscles. The Auricularis Magnus muscle is responsible for certain movements of the ear.
The Auricularis Magnus muscle arises from the temporal bone, specifically from the external acoustic meatus, and extends downward to insert into the lateral surface of the auricle or external ear. Its main function is to move the ear in a variety of directions. When contracted, it causes the ear to move upwards and backwards, while relaxing the muscle brings the ear back to its natural position.
The Auricularis Magnus muscle plays a role in enhancing the reception of sound by directing the ears towards the source of the sound, thus assisting in sound localization. It also contributes to facial expressions, particularly in certain emotions like surprise or fear, where the ears move backward reflexively.
Understanding the anatomy and function of the Auricularis Magnus muscle is significant in various medical fields, such as plastic surgery or otolaryngology. Additionally, the muscle can be targeted during certain facial exercises or massage techniques aimed at toning or relaxing the surrounding facial muscles.
