The periodontist will also take a small measuring instrument called a probe and place it between the teeth and gums to determine the depth of those spaces, known as periodontal pockets; this helps the periodontist assess the health of the gums.
The ground substance of connective tissue is different from all of these fluids; it is the liquid medium through which these other fluid exchanges take place.
The answer is connective tissue. Connective tissue is one of the four main tissue types; the others are epithelial tissue, muscle tissue and nervous tissue. Connective tissue includes tissues such as cartilage, bone, blood and fat. In this lesson, we'll be specifically looking at fibrous connective tissue. The primary purpose of connective tissue is to hold our organs and other tissues together, as well as provide support for our body as a whole.
