The spelling of the word "musculus obliquus auriculae" may seem intimidating at first, but understanding its phonetic transcription can make it more manageable. The first part, "musculus," is pronounced "ˈmʌskjʊləs." The second part, "obliquus," is pronounced "əˈbliːkwəs." Finally, "auriculae" is pronounced "ɔːˈrɪkjʊli." When put together, the word is pronounced "MUS-kyoo-luhs oh-BLEE-kwus aw-RIK-yoo-lee." This term refers to a muscle found in the ear, and it is commonly used in anatomical studies.
Musculus obliquus auriculae, also known as the oblique muscle of the auricle, is a small muscle located in the human ear. It is one of the intrinsic muscles that control the movement and positioning of the auricle, commonly referred to as the external ear.
The term "musculus" refers to a muscular structure, while "obliquus" signifies the muscle's direction or alignment. "Auriculae" refers specifically to the auricle or pinna, which is the visible, outer part of the human ear that extends from the head.
The musculus obliquus auriculae is situated in the posterior part of the auricle and consists of slender, oblique fibers. As one of the intrinsic muscles, it aids in the movement and stabilization of the external ear. When contracted, it can either pull the auricle upwards or downwards, contributing to the changes in the shape and orientation of the ear.
Although the musculus obliquus auriculae is relatively small and has limited mobility, it plays an essential role in individuals who have the ability to move their auricles voluntarily. This movement can assist in altering the position and direction of the ear, allowing for better sound reception in certain situations. Additionally, it may contribute to creating variations in the appearance or shape of the auricle, contributing to individual differences in ear morphology.
Oblique muscle of the auricle, a thin band of oblique muscular fibers extending from the upper part of the eminentia conchae to the convexity of the helix, running across the groove corresponding to the crus anthelicis inferior.
