Tendons and ligaments are made of dense connective tissue. This type of tissue is characterized by a high concentration of collagen fibers, which provide strength and support.
Tendons connect muscles to bones, allowing for the transfer of force during muscle contraction, while ligaments connect bones to other bones at joints, providing stability and support. The dense arrangement of collagen fibers in these tissues makes them resilient and capable of withstanding the tension and stress that occurs during movement.
In contrast, areolar tissue is a loose connective tissue, adipose tissue specializes in fat storage, and reticular tissue forms the framework of organs like the liver and spleen. Therefore, the correct answer is option A: Dense Connective Tissue.
