The striated plateau, also known as the brush border, is a structure found on the apical surface of some cells, such as those in the intestines and kidneys. Here are the answers to your options:

A. False. The striated plateau is not a differentiation of the cells of the respiratory epithelium.

B. True. The striated plateau is made up of ordered and mobile microvilli.

C. False. Microvilli are not stabilized by myosin.

D. True. The striated plateau increases the surface area for absorption in the intestines.

E. True. The striated plateau can be seen under an electron microscope.

F. True. The striated plateau is an apical differentiation of the cells of the intestinal epithelium.

G. False. Microvilli are not composed of troponin.

H. False. The striated plateau is not visible under optical microscopy on standard stains.

I. False. The striated plateau is not an apical differentiation of the cells of the urothelial epithelium.

J. False. The striated plateau is not a constituent of the skeletal striated muscle cell.

K. False. The striated plateau is not a neuromuscular synapse.

L. False. The striated plateau is not made up of contractile myofibrils.

M. True. The striated plateau is an apical differentiation.

N. False. The striated plateau does not have an essentially protective role, its main function is to increase the surface area for absorption.

O. True. The striated plateau is rich in glycoproteins.

P. True. The striated plateau can be highlighted by PAS (periodic acid of SHIFF) in an optical microscope.
