The term "eminentia acustica" refers to a small elevation in the floor of the fourth ventricle of the brain. In IPA phonetic transcription, its pronunciation is /ˌɛmɪˈnɛnʃə əˈkʌstɪkə/. The first word starts with the stress syllable /ˈɛmɪ/ followed by a short vowel sound /ɪ/. The second word has the stress on the third syllable /ˈkʌstɪkə/ with a schwa sound /ə/ in the second syllable, and the letter combination "sc" is pronounced as /sk/. Being able to accurately spell medical terminology is critical for healthcare professionals to communicate and document information effectively.
Eminentia acustica is a term used in human anatomy to refer to a distinctive and prominent anatomical structure found within the human ear, specifically in the inner ear. Latin in origin, the term can be translated to mean the "acoustic prominence" or the "auditory eminence."
Located within the temporal bone of the skull, the eminentia acustica is a bulging ridge or prominence on the surface of the bone. It is situated just behind and slightly above the oval window, a membrane-covered opening that separates the middle ear from the inner ear. The eminentia acustica is an important landmark as it provides attachment for some of the tiny muscles that control the movement of the ossicles (ear bones) within the middle ear.
This anatomical feature plays a crucial role in the transmission of sound waves from the outer to the inner ear. When sound waves enter the ear canal, they cause vibrations, which in turn cause the eardrum to vibrate. This vibration is then amplified and transmitted through the ossicles, ultimately reaching the oval window. The eminentia acustica helps to maintain the proper positioning and movement of the ear bones, which is essential for the efficient transmission of sound waves to the inner ear.
Overall, the eminentia acustica serves as an important anatomical structure within the human ear, allowing for the proper functioning and transmission of auditory stimuli from the external environment to the sensory receptors in the inner ear.

The term "eminentia acustica" is of Latin origin.
- "Eminentia" derives from the Latin word "eminentia", meaning prominence or projection.
- "Acustica" is derived from the Latin word "acūsticus", which comes from the Greek word "akoústikos", meaning related to hearing or auditory.
When combined, "eminentia acustica" refers to the anatomical prominence in the brainstem known as the "acoustic prominence" or "acoustic tubercle".
