New growths also sometimes take this path, starting from theciliary body and growing forward into the anterior chamber in the region of its sinus(Fig. 192). 309. Aqueous Chamber.—The iris and ciliary body take part in theformation of the two chambers of the eye. The anterior chamber is bounded. Fig. 147.—Sinus or the Anterior Chamber. Magnified 83 X , the most posterior layers of the cornea; S, those of the sclera. The boundary between the twois marked by the elongated lumen of Schlemms canal. On the posterior surface of the cornea can beseen Descemets membrane, d, with its endothelium. It ends in a thinned-out edge and just before itcomes to a stop the lamellae of the cornea which lie directly in front of it can be seen to become fibrillatedand to merge into the anterior lamellae of the ligamentum pectinatum. The ligamentum pectinatumforms the posterior wall of Schlemms canal and apparently consists solely of short fragments of the lamellae of the ligament which have been cut transversely by the section appear under the formof fibers which must show an interruption at all spots where the section happens to enter gaps betweenthe lamella?
