Basic Substance

Ground substance is the nonliving material secreted by and surrounding connective tissue cells. It often contains a dense felt-like network of microscopic fibers.

The main substance performs many important functions. It fills the space between cells, providing them with support and fixation. Also, the main substance is penetrated by blood and lymphatic vessels, through which tissue cells are nourished.

The composition of the main substance varies depending on the type of connective tissue. For example, loose fibrous connective tissue is dominated by collagen and elastic fibers. And in cartilage tissue, the main component of the main substance is cartilage tissue.

Thus, the ground substance is the most important structural component of connective tissues, ensuring their functioning.
