The capillary blood-vessels supplying the adenoid tissue receive a more or less distinct special investment from the adenoid reticulum; this is the capillary adventitia. 123, The adenoid tissue occurs as : (1) Diffuse adenoid tissue, without any definite grouping or arrangement. This is the case in the sub- epithelial layer of the mucous membrane of the trachea, in the mucous membrane of the false vocal cords and the ventricle of the larynx, in the posterior part of the epiglottis, in the soft palate and tonsils, at the root of the tongue, in the pharynx, in the mucosa of the small and large intestine, including the villi Fier. 57.—Adenoid Eeticulum shaken out; most of the Lymph-corpuscles are removed.
