What is mandibular foramen?

Mandibular foramen is an opening in the lower jaw or jaw. It acts as an input for blood vessels and mandibular nerve. The lower alveolar nerve and lower alveolar artery also enter through mandibular foramen.

Specifically, mandibular foramen is placed in Ramus. Also known as "Ramus jaws" or "perpendicular part of the jaw", it has a quadrilateral shape and covers the back of the lower jaw. Ramus has two surfaces: medium or medium, surface and side surface that carries mandibular foramen, which appears around its center. This area also has coronoid and condyloid processes that are separated by a mandibular notch.

Lower alveolar nerve and lower alveolar artery enter the lower jaw through mandibular foramen. This area of ​​the passage is the reason why the term "alveolar" is applied to both, because one meaning of the term refers to the area near the ridge of the jaw. Each structure has a distinctive function on the jaw.

also known as the lower dental nerve, the lower alveolar arteryIt is one of the branches of the mandibular nerve. This structure is the largest of the branches of the trigeminal nerve or the fifth skull nerve. The trigeminal nerve, sometimes shortened CN5, acts as the main source of facial innervation. He is also responsible for several engine functions, including biting and chewing.

Before entering the mandibular foramen, the branch of the lower alveolar nerve called mylohyoid nerves innervates mylohyoid and digastric muscles. These muscles are found between the jaw and the hyoid bone on the neck and under the lower jaw. After entering the lower alveolar nerve, it passes through the mandibular channel to become part of the sensory net called the lower dental plexus, which innervates lower teeth and gums; This reason is obtained by the lower alveolar nerve “lower dental nerve”. It also branches like a mental nerve and enters mental foramen to innervate the chin and lower lip.

As far as the lower alveolar artery is concerned, it enters intoMandibular foramen with lower alveolar nerve and travels along the mandibular canal. Like the nerve, it is also called the lower dental artery, but instead of innervation gives the lower jaw with blood. When it reaches premolar teeth, it is divided into a branch of incisors and a mental branch. The branch of incisors - so named for their way directly under the cutting teeth - is responsible for supplying blood to teeth and gums. Meanwhile, the mental branch follows the mental nerve across the mental foramen to the chin.
