Textbook of normal histology: including an account of the development of the tissues and of the organs . lymph-sinuses: a, capsule from which trabecular (b, b) extend ; c, masses of dense adenoid tissue composingthe cortical follicles ; d, the same, of the medullary cords ; e, lymph-sinuses. Fig. 145. number of simple nodules. These structures enjoy a wide distri-bution, and are represented by the numerous chains of deep and superficial lymph-glands, of which theaxillary and inguinal glands are familiarinstances. The periphery of these lymph-glandsis occupied by a firm capsule composedof fibrous connective tissue, inter-mingled with which, in the largestglands, bundles of involuntarymuscle are sometimes present. Atthe position of entrance and exit ofthe larger blood-vessels and the efferentlymphatic trunks, usually opposite themost convex surface of the organ, thecapsule dips deeply into the interior ofthe gland and forms the hilum. The space included within thecapsule is subdivided into a peripheral zone, the cortex, and acentrally situated part, the medulla, which at the hilum reaches. Section of lymphatic gland of child,including portion of cortex at periphery :c, capsule ; s, loose tissue of the lymph-sinus ; /, denser lymph-tissue of thecortical follicle. THE LYMPHATIC SYSTEM. 121 the exterior. The details of arrangement distinguishing these portionsof the gland depend primarily upon the distribution of the trabeculaewhich continue the tissue of the capsule into all parts of the Organ. The trabeculae, composed of stout bundles of fibrous tissue, ex-tend from the inner surface of the capsule towards the hilum anddivide the cortex into a number of imperfect spherical compartmentswhich enclose masses of adenoid tissue, the cortical follicles, whichcorrespond to simple lymph-follicles. The continuations of the tra-beculae towards the centre of the gland unite at much more frequentintervals and form throughout the medulla a series of incomplete par-titions which sep
