　以下が三叉神経の3つの枝となる。

　ちなみに以下が神経系の全体像となる。

「三叉神経節から出てただちに蝶形骨大翼の卵円孔を通って側頭下窩に出て硬膜、咀嚼筋、頬粘膜、耳介、外耳道付近その他へ枝を与えた後、舌神経、下歯槽神経の２終枝に分かれる。」（船戸和弥のホームページ）

　下顎神経の枝には以下のものが挙げられる。また、その分布としては以下のようになる。

「 Wikipedia 」では以下のように解説している。

「 The mandibular nerve (V3) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V).
【 Structure 】
The large sensory root emerges from the lateral part of the trigeminal ganglion and exits the cranial cavity through the foramen ovale. The small motor root of the trigeminal nerve passes under the ganglion and through the foramen ovale to unite with the sensory root just outside the skull.
The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior and large posterior trunk.
The anterior division gives off branches to the four main muscles of mastication and a buccal branch which is sensory to the cheek. The posterior division gives off three main sensory branches, the auriculotemporal, lingual and inferior alveolar nerves and motor fibres to supply mylohyoid and the anterior belly of the digastric muscle.
【 Branches 】
The mandibular nerve gives off the following branches:
