What function does fibrous connective tissue serve in the body?

Fibrous connective tissue plays a crucial role in providing structural support throughout the body. Its primary function is to hold body structures together, which includes connecting muscles to bones (tendons), and bones to other bones (ligaments). This type of tissue is composed of densely packed collagen fibers, which give it strength and flexibility. As a result, fibrous connective tissue is essential for maintaining the integrity and stability of various organs and systems within the body, ensuring that they function properly and are able to withstand stresses and strains.

In contrast, the other options highlight various functions not associated with fibrous connective tissue. Insulation is primarily a function of adipose tissue, energy storage is associated with adipose cells, and hormone production is typically the role of endocrine glands and specific tissues within the body, not connective tissue.
