The term "suprameatal spine" is commonly used in the field of anatomy, particularly with reference to the human ear. It refers to a small bony protrusion located just above the ear canal. The spelling of this word can be broken down using IPA phonetic transcription, which would be /suːprəmiːtəl/spaɪn/. The first syllable "su" represents the prefix "super-", meaning "above", while "meatal" refers to the ear canal. "Spine" of course, refers to a bony projection or ridge. Together, these terms describe the location and shape of the suprameatal spine.
The term "suprameatal spine" refers to a specific anatomical structure found within the human skull. It is located in the temporal bone, specifically in the area above the opening known as the external acoustic meatus, which is the passage leading to the ear canal. The suprameatal spine is typically a small projection or bony ridge that extends horizontally across the temporal bone, serving as a landmark for various anatomical and surgical references.
Functionally, the suprameatal spine is crucial for medical professionals, particularly those specializing in otology or neurosurgery. Its precise location aids in identifying adjacent structures during surgical procedures, such as cochlear implantation or mastoidectomy. Additionally, the suprameatal spine plays a role in determining the depth of penetration during these interventions, contributing to accurate and safe surgical outcomes.
From a descriptive standpoint, the term "suprameatal" is derived from the combination of two Latin words: "supra" meaning above or on top of, and "meatus" referring to an opening or passage. Therefore, the suprameatal spine can be understood as a bony prominence situated above the external acoustic meatus.
In conclusion, the suprameatal spine is a small bony projection located above the external acoustic meatus in the temporal bone. It serves as an anatomical reference for surgical procedures involving the ear and adjacent structures.

The word "suprameatal spine" is a specialized medical term, consisting of two separate terms: "suprameatal" and "spine". Let's break it down:
1. Suprameatal: The term "suprameatal" is derived from two parts:
- "Supra-" is a prefix in Latin, meaning "above" or "over".
- "Meatus" is a Latin word meaning "opening" or "passage".
Hence, when combined, "suprameatal" refers to a location or position above or over a meatus or opening.
2. Spine: The term "spine" is derived from the Latin word "spina" which means "thorn" or "spike". In anatomy, "spine" generally refers to a bony projection or process.
