11. The profuse binding of ricin to surface membranes allows internalization with all types of membrane invaginations . 12. During the first formation of an invagination in the cytoplasmic membrane is triggered by a GTPase. 13. Repeated invagination of the cytomeres gives rise to the merozoites which also have a trilaminar membrane. 14. This occurs by invagination , meaning the inward folding of the lysosomal membrane, or cellular protrusion. 15. Over-excitation of this receptor induces receptor remodeling and the eventual invagination of the GABA receptor. 16. The stomatedeum and proctodeum are invaginations of the epidermis and are lined with cuticle ( intima ). 17. The aim is to produce a self-cleansing cavity, which becomes an invagination of oral tissues. 18. Besides ingression, two other types of internalizing cell movements may occur during gastrulation : invagination and involution. 19. The foreskin of a capybara is attached to the anus in an unusual way, forming an anogenital invagination . 20. Like rods, the outer segments of cones have invaginations of their cell membranes that create stacks of membranous disks.
