Alveolar ridge

The Alveolar ridge (/ælˈviːələr rɪdʒ/) is a term used in anatomy and phonetics to refer to the bony ridge located at the roof of the mouth, just behind the upper front teeth (the incisors).

Etymology

The term "alveolar" is derived from the Latin word alveolus, meaning "small cavity". This is in reference to the socket in the jawbone where the root of a tooth is embedded. The term "ridge" refers to the raised or protruding section of the alveolar process.

Anatomy

The alveolar ridge is a part of the maxilla and mandible that contains the sockets (alveoli) of the teeth. It is divided into two parts: the maxillary alveolar ridge and the mandibular alveolar ridge, corresponding to the upper and lower jaw respectively.

Phonetics

In phonetics, the alveolar ridge is an important place of articulation. Many consonants (such as /t/, /d/, /n/, and /l/) are described as "alveolar", meaning they are articulated with the tip of the tongue against the alveolar ridge.
