Connective tissue is one of the basic tissues of the body and is composed of cells and a large amount of extracellular matrix. The connective tissue of the head includes the intrinsic connective tissue of the head, bone tissue, blood, and lymph. The term connective tissue is generally used to refer to the intrinsic connective tissue, which is divided into lax connective tissue, dense connective tissue, adipose tissue, and reticular connective tissue. Connective tissues play a major role in the human body in connecting, supporting and protecting nutrient transport. There are multiple functions in connective tissue, depending on the type of cells and the different types of fibers involved. Briefly, the connective tissue of the head includes the skull, the blood and lymphatic tissues of the head, and some other subcutaneous tissues. The above information is for reference only.
