Labial Branches of the Inferior Mental Nerve

labial branches of the inferior mental nerve - (rami labiales inferiores, pna) depart from the lower trunk of the inferior alveolar nerve. They innervate the skin of the lower lip, the mucous membrane of the anterior parts of the floor of the mouth and the mucous membrane of the lower gum.

The labial branches of the inferior mental nerve are sensitive and innervate the area of ​​the lower lip, floor of the mouth and gums. Damage to these nerves can cause the area to become numb.

Introduction

The labial branches of the inferior mental nerves are paired nerve fibers that are responsible for transmitting signals from the mandibular nerve to the labial muscle and oral mucosa. They are part of the anterior maxillary branch of the mandibular neck. In this article we will consider the main characteristics and functions of the labial branches of the inferior mental nerves.

Description

The lower lip starts from the lip on the bone and goes into the space of the labial fissure between it and the upper teeth. The labial branch of the inferior mental nerve branches from the inferior lingual nerve in the mandible and travels to the anterior part of the tongue. Along the way, the nerves pass through the labial fissure, where they pass into the oral serosa.

The lips transmit signals down through the inferior mental nerves to the muscle located above them. These signals are associated with the forward and backward movement of the jaw, as well as the closing and opening of the mouth. The inferior mental nerves also control sensation in the lips and mucous membranes.

In addition, the lower mental branches are involved in controlling the position of the corners of the mouth and the movements of the upper and lower jaws. The lower lip also controls the triangular facial plate that lies beneath it and is involved in controlling the adjustment of the position of the soft tissues in the mouth.
