The tubal tonsil (tonsilla tubaria) is a paired, aggregate of lymphoid tissue in the form of an interrupted plate in the thickness of the mucous membrane of the tube roller, in the region of the pharyngeal opening and the cartilaginous part of the auditory tube. The amygdala consists of diffuse lymphoid tissue and a few lymphoid nodules. The mucous membrane above the amygdala is covered with ciliated (multicellular ciliated) epithelium. Pipe tonsil is fairly well expressed in a newborn (its length is 7.0-7.5 mm), and its greatest development reaches 4-7 years. Children on the surface of the mucous membrane in the area of the tubal tonsil are seen small tubercles, under which there are accumulations of lymphoid tissue - lymphoid nodules. Lymphoid nodules and breeding centers in them appear on the 1st year of the child's life. The age-old involution of the tubal tonsil begins in adolescence and adolescence.
Development of tubal tonsils
The development of the tubal tonsil begins at the 7-8th month of the fetal life in the thickness of the mucous membrane around the pharyngeal opening of the auditory tube. First, separate clusters of the future lymphoid tissue appear, from which the tubular tonsil forms later.
[Vessels and nerves of the tubal tonsils
Blood to the tubal amygdala flows along the branches of the ascending pharyngeal artery. Venous blood from the amygdala flows into the veins of the pharyngeal plexus. Nerve fibers come in the composition of the branches of the facial, glossopharyngeal and vagus nerves, as well as from the periarterial sympathetic plexuses.
