CN V - Trigeminal Mandibular Branch
Branch | Comes From? | Goes to? | How? | Components |
---|---|---|---|---|
N. to Tensor Tympani | Foramen Ovale (Undivided Trunk) | Tensor Tympani | GSE | |
N. to Tensor Veli Palatini | Foramen Ovale (Undivided Trunk) | Tensor Veli Palatini | GSE | |
N. to Medial Pterygoid | Foramen Ovale (Undivided Trunk) | Medial Pterygoid | GSE | |
Recurrent Meningeal N. | Foramen Ovale (Undivided Trunk) | Dura Skull Mucosa of Mastoid Air Cells | GVA? | |
Masseteric N. | Foramen Ovale (Anterior Division) | Masseter Muscle | Between TMJ and Temporalis with Masseteric A. | GSE |
N. to Lateral Pterygoid | Foramen Ovale (Anterior Division) | Lateral Pterygoid | Branches off after Masseteric N. | GSE |
Deep Temporal N. | Foramen Ovale (Anterior Division) | Temporalis Muscle | Branches off after Lat. Pterygoid N. | GSE |
Buccal N. | Foramen Ovale (Anterior Division) | Skin and mucosa of cheek adjacent gingiva | Between Lateral and Medial Pterygoid through ramus and meets up with Buccal Branch of CN VII | GVA? |
N. to Mylohyoid | Foramen Ovale (Posterior DIvision) | Mylohoid Ant. Belly of Digastric | Branches off of Inferior Alveolar N.,goes through deep surface of ramus of mandible through mylohoid groove | GSE |
Auriculotemporal | Foramen Ovale (Posterior Division) | TMJ Tympanic Membrane skin over auricle, temporalis, parotid, external auditory canal | Branches off and goes backward over zygomatic process of temporal bone splits to let middle meningeal artery through | GVA |
Inferior Alveolar | Foramen Ovale (Posterior Division) | Alveolar Processes of Mandible Adjacent Gingiva | Goes with lingual between lateral and medial pterygoid muscles and through enters mandibular foramen, courses through mandibular canal, exits via mental foramen | GVA |
Mental N. | Mental Foramen | skin of chin and lower lip, mucosa and adjacent gingiva | exits mental foramen | GVA |
Lingual N. | Foramen Ovale (Posterior Division) | Mucosa of ant. 2/3 of tongue mucosa on floor of mouth adjacent gingiva | Between lateral and medial pterygoid muscles and anterior to Inferior Alveolar and then crosses ramus of mandible | GVA |
Mandibular Branch | Pons --> trigeminal ganglion | Foramen Ovale |
