intima - the innermost membrane of an organ (especially the inner lining of an artery or vein or lymphatic vessel)
iris - muscular diaphragm that controls the size of the pupil which in turn controls the amount of light that enters the eye; it forms the colored portion of the eye
lamella - a thin membrane that is one of the calcified layers that form bones
meninges, meninx - a membrane (one of 3) that envelops the brain and spinal cord
mucosa, mucous membrane - mucus-secreting membrane lining all body cavities or passages that communicate with the exterior
