These are called microvilli which means shaggy hair. They are tiny hairlike folds in the plasma membrane that extend from the surface of some cells. They are be seen as a "brush border" with a light microscope.

What does microvilli do in a cell?
Microvilli (singular: microvillus) are microscopic cellular membrane protrusions that increase the surface area of cells. They are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.
Why are micro-villi an important modification?
Microvillus are tiny cellular membranes that through microscopic protrusions increase the surface area of cells and are involved in many cellular processes, such as absorption, secretion, and adhesion.
What are Factors that increase the secretion of antidiuretic hormone?
Water conservation and thirst center
The rate of secretion of parathyroid hormone increases when?
serum calcium levels increase
Is decrease GI motility and secretion has a cholinergic effect?
Acetylcholine is a neurotransmitter in the GI tract (among other places). An increase in acetylcholine activity (also known as cholinergic activity) results in an increase in GI motility and secretion, not a decrease.
Why cell needs microvilli like structures?
Microvilli are microscopic cellular membrane protrusions that increase the surface area of cells and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.

What type of cell functions does the presence of microvilli typically indicate?
Microviili increase the plasma membrane surface area. They are generally found in absorptive cells. (e.g. intestinal cells)
What is the function of the microvilli?
They are located in the small intestine and help with absorption of nutrients from digested food. They also increase a cells surface area
What is the purpose of the microvilli in the proximal convoluted tubule?
Microvilli are the finger like projections present on the outer surface of the cell. Their function is to increase the surface area of the cells through which the diffusion of materials both into and out of the cell occur. They are also involved in absorption, secretion and cellular adhesion.
What slender extensions of the plasma membrane that increase its surface area?
Microvilli:In some cells the membrane is thrown into minute fingerlike projections or folds called microvilli which greatly increase the surface area of the cell available for absorption or passage of materials and for the binding of signaling molecules.
How can you increase your absorption of dietary magnesium?
Vitamin A increases the absorption of magnesium.
Diuretics are administered to increase urine secretion?
Yes.
How can sodium losses in the urine during water-induced diuresis be replaced?
-Increase in alderstone secretion -Decrease in glomerular filtration rate (GFR) -Increase in ADH (antidiuretic hormone) secretion -Decrease in secretion of atrial natriuretic peptide
Can absorption of waves increase the temperature of objects?
Yes, thetemperature Will increase.
What are fingerlike projections of cytoplasm?
Fingerlike projections of cytoplasm and known as pseudopod(s). Pseudopd organisms are typically found on in the microscopic subkingdom of Protozoa( genus Amoeba).
