Which of the following is NOT an example of dense regular connective tissue?

• A. Tendons
• B. Ligaments
• C. Adipose tissue
• D. Aponeuroses

Answer: (C)

Dense regular connective tissue is organized with densely packed collagen fibers aligned in the same direction, giving high tensile strength along that axis. This structure is ideal for transmitting force, as seen in tendons (muscle to bone), ligaments (bone to bone), and aponeuroses (flat sheets). Adipose tissue, by contrast, is a type of loose connective tissue specialized for fat storage. Its matrix is loose and dominated by large adipocytes, with relatively sparse collagen fibers not arranged in parallel. This makes adipose tissue poorly suited for resisting pulling forces in a single direction, unlike dense regular tissue. So, adipose tissue is not an example of dense regular connective tissue.
