Surrounding each muscle fiber (cell) is a delicate external lamina composed primarily of reticular fibers. This external lamina is produced by the muscle fiber and, when observed through the light microscope, cannot be distinguished from the cell membrane of the muscle fiber, the sarcolemma.
Epiretinal membrane. An epiretinal membrane (ERM) is scar tissue that has formed on the surface of the macula, located in the center of the eyeâs light-sensitive tissue called the retina.The macula provides the sharp, central vision we need for reading, driving, and seeing fine detail.hen this happens, the retina begins a healing process to the damaged area and forms scar tissue, or an epiretinal membrane, on the surface of the retina. This scar tissue is firmly attached to the retina surface.
