External lamina is a structure similar to basal lamina that surrounds the sarcolemma of muscle cells. It is secreted by myocytes and consists primarily of Collagen type IV, laminin and perlecan (heparan sulfate proteoglycan). Nerve cells, including perineurial cells and Schwann cells also have an external lamina-like protective coating.
Adipocytes also have an external lamina

“Without free, self-respecting, and autonomous citizens there can be no free and independent nations. Without internal peace, that is, peace among citizens and between the citizens and the state, there can be no guarantee of external peace.”
