The inferior alveolar artery (inferior dental artery) is an
Structure
Course
It passes inferior-ward through the infratemporal fossa[1] as part of a neurovascular bundle with the inferior alveolar nerve and vein to the mandibular foramen.[2] In the infratemporal fossa, it is situated posterior to the inferior alveolar nerve, lateral to the skull, and medial to the sphenomandibular ligament.[1]
It enters the
Branches
The inferior alveolar artery and its incisor branch during their course through mandibular canal issue a few twigs which are lost in the
Lingual branch
Near to its origin, the inferior alveolar artery issues a lingual branch which passes inferior-ward alongside the lingual nerve. It provides arterial supply to the mucous membrane of the tongue.[1]
Incisor branch
The incisor branch is continued anterior-ward inferior to the incisor teeth as far as the midline where it anastomoses with its contralateral partner (sometimes an incisor branch continue across the midline to the other side).[1]
Mental branch
The mental branch exits the mandibula anteriorly at the
Mylohyoid branch
The inferior alveolar artery emits the mylohyoid branch before entering the
