This allows accommodating the stretch that occurs in vessels and other organs during the movements of the body. Loose Connective Tissue: The loose connective tissue mainly contains fibroblasts. Loose connective tissue. Accordingly the proper connective tissue have been divided into two types-loose and dense connective tissue; Types of proper connective tissue. Table 5.1 lists some of the subcategories of connective tissue proper, along with some of their characteristics and properties. The dense connective tissues are then classified into two groups known as dense irregular connective tissue and dense regular connective tissue. Both dense regular and dense irregular connective tissue are inelastic. They are somewhat less flexible than loose connective tissue. - It holds organ in place and attaches epithelial tissue to other underlying tissues. The loose connective tissue is more cellular, with smaller caliber collagen and elastic fibers than the coarser, dense irregular connective tissue. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. It mainly surrounds the blood vessels and nerves. There are three main groups of connective tissues: Loose connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. “Anatomy and physiology of animals loose connective tissue” By The original uploader was Sunshineconnelly at English Wikibooks – Transferred from en.wikibooks to Commons by Adrignola using CommonsHelper.

Fibrous connective tissues contain large amounts of collagen fibers and few cells or matrix material. Dense Connective Tissue: The three types of dense connective tissue are dense regular, dense irregular, and elastic tissue. AREOLAR TISSUE 26. Whereas, the dense connective tissue is present on the outside of many organs, in the dermis of the skin and submucosa, within various organs as dense irregular connective, and in tendons, ligaments, and aponeuroses as dense regular connective tissue. Connective tissue fills the surfaces between the other types of tissues in the body. 3. The dense irregular connective tissue contains collagen fibers that run in all directions. Areolar connective tissue – The areolar connective tissue is a loose array of fibers consists of various types of cells. Dense connective tissue (dense regular, dense irregular, and elastic) What is the primary function of connective tissue? That means dense connective tissue consists of numerous protein fibers in the matrix. Fibres and fibroblasts are compactly arranged. The difference between loose connective tissue and dense connective tissue is how many fibers are present in the matrix. 1.“Loose Connective Tissues.” Loosects, Available here. On the basis of the … The dense connective tissues are then classified into two groups known as dense irregular connective tissue and dense regular connective tissue. In the case of loose connective tissue, the cells are very loosely packed and the tissue is quite soft, in contrast with fibrous or dense connective tissue, where the fibroblasts are very densely arranged and the tissue is extremely firm. In addition to fibroblasts, the cell population is heterogeneous, including both indigenous and emigrant connective tissue cells (see Fig. However, it consists of many cells. Elastic fibers. Loose Connective Tissue. Moreover, few loosely arranged fibres can be found in loose connective tissue, whereas in the dense connective tissue, fibres are abundant and densely arranged. “Normal Epidermis and Dermis with Intradermal Nevus 10x” By Kilbad – Own work (Public Domain) via Commons Wikimedia The bands called tendons and capsules in the joints are formed by dense connective tissue. 3.

Connective tissues are made up of two proteins: collagen and elastin. Both loose and dense connective tissues provide structural support and connect various types of tissues in the body. The most characteristic feature of areolar and adipose tissues is their elasticity. Dense Connective Tissue: The dense connective tissue mainly contains fibrocytes. They occur in places where vessels, nerves, and ducts pass through the tissues. Areolar tissue, found in the hypodermis of the skin and below the epithelial layers of the digestive, respiratory, and urinary tracts, is a loose connective tissue proper, as is adipose tissue, also known as fat. Loose connective tissue is found around every blood vessel, helping to keep the vessel in place. Areolar tissue, reticular tissue, and adipose tissue are some categories of loose connective tissue. -It plays a significant role in the diffusion of gases, nutrients and metabolic wastes between the cells and the vessels that perfuse the tissue. The dense regular connective tissue contains parallelly arranged collagen fibers in a single direction. 1.
