The meridional fibers, much the more numerous, arise from the posterior margin of the scleral spur (page 1007); they run backward, and are attached to the ciliary processes and orbiculus ciliaris.

They are attached by their periphery to three or four of the ridges of the orbiculus ciliaris, and are continuous with the layers of the choroid: their opposite extremities are free and rounded, and are directed toward the posterior chamber of the eyeball and circumference of the lens.
