Adipose tissue is specialised to store fats. 3. Types of Connective Tissue. Loose (areolar connective tissue) is the most abundant form of collagenous connective tissue. Connective tissue proper includes loose connective tissue and dense connective tissue. ? What are the Similarities Between Loose and Dense Connective Tissue – Outline of Common Features 4. It mainly surrounds the blood vessels and nerves. If it has a few fibers, it is loose. The dense regular and irregular connective tissue are shown in figure 2. - It holds organ in place and attaches epithelial tissue to other underlying tissues. That means dense connective tissue consists of numerous protein fibers in the matrix. Dense Connective Tissue. However, it consists of many cells. It consists of loosely arranged fibres and cells. Overview and Key Difference Dense Connective Tissue: The dense connective tissue mainly contains fibrocytes. Even though fibres are not abundant in loose connective tissue, collagen fibres are the main fibre type present in loose connective tissue. The tissue is also found around and between most body organs. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue . They are somewhat less flexible than loose connective tissue. 2. Loose Connective Tissue. Non-specialized or general connective tissue, sometimes called connective tissue proper, is subdivided into two groups: loose and dense. ? In summary, areolar tissue is tough, yet flexible, and comprises membranes. Loose connective tissue is the most common type of connective tissue in vertebrates and it holds the organs in place and attaches the epithelial tissue to the underlying tissues. Reticular, collagen, and elastin are the three types of protein fibers that specifically occur in the connective tissue. Dense Connective Tissue: Dense connective tissue produces tendon and ligaments by forming strong, rope-like structures. Furthermore, a large proportion of ground substance and cells are present in loose connective tissue, whereas these substances are present in small quantities in dense connective tissue. It forms structures like tendons in which the forces are directed in a single direction. The location and the function of each type of loose connective tissue are described in table 1. Depending on the arrangement of fibres, dense connective tissue exists in two distinct forms: dense irregular connective tissue and dense regular connective tissue. 2.“Loose Connective Tissue Types, Location, and Function.” Quizlet, Available here.
