Mandibular notch
Encyclopedia
The upper border of the ramus of mandible is thin, and is surmounted by two processes, the coronoid process
anteriorly and the condyloid process
posteriorly, separated by a deep concavity, the mandibular notch. It allows the passage of the masseteric nerve
(a branch of the mandibular nerve (V3)
division of the trigeminal nerve
), masseteric artery
and masseteric vein.
Coronoid process
The Coronoid process can refer to:* The coronoid process of the mandible, part of the ramus mandibulae of the mandible...

Condyloid process
The condyloid process is part of the mandible and is thicker than the coronoid, and consists of two portions: the condyle, and the constricted portion which supports it, the neck.-Condyle :...

Masseteric nerve
The masseteric nerve passes laterally, above the Pterygoideus externus, in front of the temporomandibular articulation, and behind the tendon of the Temporalis; it crosses the mandibular notch with the masseteric artery, to the deep surface of the Masseter, in which it ramifies nearly as far as its...

Mandibular nerve
The mandibular nerve is the largest of the three branches of the trigeminal nerve.-Roots:It is made up of two roots:* a large sensory root proceeding from the inferior angle of the trigeminal ganglion....
division of the trigeminal nerve
Trigeminal nerve
The trigeminal nerve contains both sensory and motor fibres. It is responsible for sensation in the face and certain motor functions such as biting, chewing, and swallowing. Sensory information from the face and body is processed by parallel pathways in the central nervous system...

Masseteric artery
The masseteric artery is small and passes laterally through the mandibular notch to the deep surface of the masseter muscle, which it supplies.It anastomoses with the masseteric branches of the external maxillary artery and with the transverse facial artery....
