Abstract
The membranous layer of the lingual fascia is thickest in the area of the V-shaped sulcus terminalis and becomes thinner towards the tip and the sides of the tongue, fading away at the margins. There is a very thin layer only in the lingual tonsil, consisting of a network of collageneous fibers arranged diagonally to the longitudinal axis of the tongue. Through the meshes of the network pass the muscle fibers or their tendons and the vessels and nerves of the mucous membrane. The network is termed "stratum reticulare." There are variations in the width of the meshes, and the angles of the crossing fibers may be altered during different stages of contraction of the tongue. Some muscle fibers end in tendons in the network and the tendons can be traced to the stratum papillare. Other muscle fibers end in collageneous or elastic tendons in the connective tissue of the papillae after having passed the stratum reticulare. The stratum reticulare is probably a supporting plate, by the meshes of which the compression of the vessels and of the nerves will be prevented.
