Question

The most widely distributed connective tissue proper is

• A. areolar tissue
• B. adipose tissue
• C. collagenous tissue
• D. reticular tissue

Answer 1

The correct option is A areolar tissue

Areolar connective tissue (or loose connective tissue) is the most widely distributed type of connective tissue in invertebrates. Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue. Collagen is the main structural protein in the extracellular matrix found in the body's various connective tissues.

Adipose tissue is a specialised connective tissue consisting of lipid-rich cells called adipocytes. The main function of adipose tissue is to store energy in the form of lipids (fat).

Reticular tissue, a type of loose connective tissue in which reticular fibers are the most prominent fibrous component, forms the supporting framework of the lymphoid organs, bone marrow and liver.

Hence, the correct answer is areolar tissue.
