Hi!
An example of a membrane would be Pericardium. This membrane in particular will cover the heart.
What is the Pericardium?
This membrane is a thin, double layered membrane which protects the heart from injuries as well as external blows.In between the membranes, there is a fluid known as pericardial fluid that is present. The function of this is to also protect the heart.
Hope I could help!

<span>Erythrocytes, neurons, skeletal cells, and columnar cells are examples of: specialized cells.
cell, in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g., bacteria
and protozoans
, in which the single cell performs all life functions. In higher organisms, a division of labor has evolved in which groups of cells have differentiated into specialized tissues
, which in turn are grouped into organs and organ systems.
Cells can be separated into two major groups—prokaryotes, cells whose DNA is not segregated within a well-defined nucleus surrounded by a membranous nuclear envelope, and eukaryotes
, those with a membrane-enveloped nucleus. The cyanobacteria and bacteria (kingdom Monera
) are prokaryotes. They are smaller in size and simpler in internal structure than eukaryotes and are believed to have evolved much earlier (see evolution
). All organisms other than cyanobacteria and bacteria consist of one or more eukaryotic cells.
All cells share a number of common properties; they store information in genes
made of DNA (see nucleic acid
); they use proteins
as their main structural material; they synthesize proteins in the cell's ribosomes using the information encoded in the DNA and mobilized by means of RNA; they use adenosine triphosphate.
as the means of transferring energy for the cell's internal processes; and they are enclosed by a cell membrane, composed of proteins and a double layer of lipid
molecules, that controls the flow of materials into and out of the cell.</span>
