Question

Which of the following cells are found in areolar tissue?
A.Mast cells
B.Plasma cells
C.Histiocytes
D.All of these

Answer 1

Under the epidermis layer, the areolar tissue is located and is also below the epithelial tissue in all body systems that have external openings. It makes the skin elastic and allows it to withstand the pain of pulling.

Complete Answer:
Areolar tissue is a common form of loose connective tissue (and invertebrates are the most widely distributed type of connective tissue). "It is so-called because its fibres are far enough apart to leave sufficient open space between them for interstitial fluid (areolar for a" little open space "is Latin). It is powerful enough to bind various types of tissue together, but soft enough to provide flexibility and cushioning. It exhibits interlacing, poorly arranged fibres, plentiful blood vessels, and interstitial fluid-filled with the substantial room.
Many neighbouring epithelial tissues (which are avascular) derive their nutrients from the areolar tissue interstitial fluid; in many-body places, the lamina propria is areolar. Its fibres pass in random directions and are primarily collagenous, but there are also elastic and reticular fibres.In appearance, Areolar tissue is highly variable. It occurs as a loose arrangement of collagenous and elastic fibres in several serous membranes, dispersed cells of different kinds; abundant ground substance; multiple blood vessels. It is more compact and often hard to differentiate from thick irregular connective tissue in the skin and mucous membranes.

Hence the correct answer is option “D”.

Note: Areolar connective tissue locks organs in place and connects other underlying tissues to epithelial tissue. For surrounding tissues, it often acts as a source of water and salts. Nearly all cells get their nutrients from the isolar connective tissue and release their waste into it.
