What is the term for the structure that pertains to the eardrum and is used to measure temperature?

• A. Tympanic
• B. Bronchial
• C. Alveolar
• D. Coronary

Answer: (A)

The term that pertains to the eardrum and is commonly used in the context of measuring temperature is "tympanic." The tympanic membrane, or eardrum, is a thin tissue that separates the outer ear from the middle ear and plays a crucial role in the auditory system. Tympanic thermometers measure the temperature inside the ear canal. They work by detecting the infrared radiation emitted by the eardrum, providing a quick and generally accurate reading of the body's core temperature.

Understanding the function of tympanic thermometers is important in clinical settings, especially for patients who may be difficult to assess using traditional methods, such as oral or rectal thermometers. This method is often less invasive and can yield results rapidly, making it particularly useful in emergency and pediatric care. The other terms—bronchial, alveolar, and coronary—are related to other anatomical structures and physiological functions but do not pertain to the measurement of temperature using the eardrum.
