Dictionnaire français - anglais

Insert the needle 1 cm above the occlusive surface of the teeth in the triangle at the lingula.

The living genus Lingula differs little from a Cambrian fossil relative more than 510 million years old.

The lingula is a bony projection on the medial surface of the ramus 1 cm above the occlusive plain.

The goal is to insert the needle just superior and posterior to the lingula; if the needle is inserted too low, anesthesia does not occur.

For example: Lingula (a brachiopod); stromatolites, which had been confined to marginal environments since the Ordovician; Pleuromeia (a small, weedy plant); Dicroidium (a seed fern).[78][79][80]
