Finger-like extensions of the cell surface membrane are found in epithelial cells, particularly in the form of microvilli. These structures increase the surface area of the cell, enhancing its ability to absorb nutrients and other substances. Microvilli are commonly found in cells lining the intestines and the kidneys, where they play a crucial role in absorption and secretion.
Microvilli are plasma membrane extensions that create the most surface area for the cell. These finger-like projections are found in cells involved in absorption, such as the cells lining the small intestine, and increase the cell's ability to transport nutrients.

The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
cytoskeleton is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to, as well as forming organelles that extend from the cell. Indeed, cytoskeletal elements interact extensively and intimately with the cell membrane.[4] Anchoring proteins restricts them to a particular cell surface - for example, the apical surface of epithelial cellsthat line the vertebrate gut - and limits how far they may diffuse within the bilayer. The cytoskeleton is able to form appendage-like organelles, such as cilia, which are microtubule-based extensions covered by the cell membrane, and filopodia, which are actin-based extensions. These extensions are ensheathed in membrane and project from the surface of the cell in order to sense the external environment and/or make contact with the substrate or other cells. The apical surfaces of epithelial cells are dense with actin-based finger-like projections known as microvilli, which increase cell surface area and thereby increase the absorption rate of nutrients. Localized decoupling of the cytoskeleton and cell membrane results in formation of a bleb.Source(s):VV....I...I
the cellular membrane is the hard surface that surrounds the cell.
Microvilli are slender extensions of the plasma membrane that increase its surface area. They are found in cells involved in absorption, such as in the small intestine, where they help in increasing the efficiency of nutrient absorption.
Fingerlike projections of cytoplasm are known as pseudopodia. These structures are temporary extensions of the cell membrane that are used for cell movement, phagocytosis, and capturing prey in some organisms like amoebas.

cell membrane is the most outer part of a cell. cell membrane is very big in surface.
In plant cell the cell surface membrane is right against the cell wall
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
