ANNULUS TYMPANICUS Meaning and
Definition
-
The term "annulus tympanicus" refers to a specific anatomical structure located within the ear. It is commonly known as the tympanic ring or tympanic sulcus. The annulus tympanicus is a circular or ring-shaped groove that surrounds the tympanic membrane, commonly known as the eardrum.
Anatomically, the annulus tympanicus can be found within the middle ear, specifically in the temporal bone. It provides support and attachment to the tympanic membrane, securing it in place. This structure acts as a stable framework for the eardrum and helps to maintain its integrity.
The annulus tympanicus consists of a fibrous connective tissue, composed of collagen fibers. It forms a complete loop, enclosing the lateral portion of the tympanic membrane. The anterior and posterior ends of the annulus tympanicus connect to the bony structure of the temporal bone, ensuring its fixation.
The importance of the annulus tympanicus lies in its role in maintaining the proper functioning of the eardrum. It helps to transmit sound waves from the external auditory canal to the middle ear, facilitating the process of hearing. Additionally, the annulus tympanicus plays a crucial role in protecting the delicate inner ear structures by providing support to the eardrum.
In summary, the annulus tympanicus is a circular groove or ring-shaped structure that surrounds the tympanic membrane. It is located within the middle ear and serves to support and secure the eardrum, facilitating the process of hearing.
