Bony structures of the mandible.
Mandibular notch
Incisura mandibulae
1/2
Synonyms: none

The mandibular notch, also known as the mandibular incisure or sigmoid notch, is the concave U-shaped groove found on the superior part of the ramus of the mandible. It is bounded by the two processes of the ramus of the mandible; the coronoid process anteriorly and the condylar process posteriorly.

The masseteric nerve, a branch of the mandibular nerve (CN V3), as well as the masseteric vessels all pass over the mandibular notch in order to reach the deep side of the masseter muscle to supply it. 

Terminology English: Mandibular notch
Latin: Incisura mandibulae
Definition Large notch between the coronoid and condylar processes of the mandible 
Function Allows for passage of the masseteric nerve, artery and vein
