Which one of the following is NOT composed of dense connective tissue?

Adipose tissue is indeed not composed of dense connective tissue. Instead, it is a type of loose connective tissue that primarily serves as a fatty tissue for energy storage, insulation, and protection of organs. The primary component of adipose tissue is adipocytes (fat cells), which store lipids and are supported by a network of collagen fibers, but do not have the dense structure characteristic of dense connective tissues.

Tendons, on the other hand, are composed of dense regular connective tissue, which consists of tightly packed collagen fibers that provide strength and resilience to withstand the forces of muscle contraction. Elastin is a protein found in various connective tissues that allows them to resume their shape after stretching or contracting, and while elastin itself is part of the connective tissue framework, it is typically present in more elastic forms of connective tissue rather than dense connective tissue. Cartilage is a type of connective tissue that provides support and flexibility, and while it is not classified as dense connective tissue, it is still a specialized form of connective tissue distinct from the other types mentioned.

In summary, adipose tissue stands out as the option that does not belong to the category of dense connective tissue due to its loose structure and primary function related to fat storage rather than providing tensile
