What part of the tympanic membrane is referred to as the pars tensa?

• A. A small triangular area at the top edge
• B. The greater part of the tympanic membrane
• C. The center of the tympanic membrane
• D. The area where the malleus is attached

Answer: (B)

The pars tensa is indeed referred to as the greater part of the tympanic membrane. This area constitutes the majority of the membrane's surface area and is characterized by its tight, tense structure, which effectively vibrates in response to sound waves. The significance of the pars tensa lies in its role in facilitating sound transmission to the inner ear. In contrast, the pars flaccida is the smaller portion of the tympanic membrane, located above the pars tensa. This area is less taut, which makes it more susceptible to conditions such as cholesteatomas. The remaining options refer to specific anatomical features that do not encompass the entirety of the pars tensa, thus highlighting why the understanding of the tympanic membrane's anatomy is essential in audiology and hearing instrument specialization.
