Loose connective tissue is found around every blood vessel, helping to keep the vessel in place. They occur in places where vessels, nerves, and ducts pass through the tissues. Depending on the arrangement of fibres, dense connective tissue exists in two distinct forms: dense irregular connective tissue and dense regular connective tissue. The dense connective tissues are then classified into two groups known as dense irregular connective tissue and dense regular connective tissue. I. loose connective tissue Fibroblasts lie in rows between the collagen packages. It holds organs in place and attaches epithelial tissue to other underlying tissues. Compare the Difference Between Similar Terms. Even though fibres are not abundant in loose connective tissue, collagen fibres are the main fibre type present in loose connective tissue. Loose connective tissue. 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. Fibrous connective tissues contain large amounts of collagen fibers and few cells or matrix material. Dense Connective Tissue. The dermis of the skin is composed of loose connective tissue interfacing with an underlying dense irregular connective tissue. It also helps to supply nutrients and oxygen to the epithelial tissue. 3. The lamina propria of this fallopian tube is pale pink. – Attaches epithelium to the underlying tissues, – Provides oxygen and nutrients to the epithelium, – Forms the structural framework of the soft organs. The connective tissue proper is further divided as loose connective tissue and dense connective tissue.In contrast, specialized tissue consists of the adipose tissue, hematopoietic tissue, bone tissue, and blood tissue. Their main function is to support and transmit mechanical forces. We also talked about the three cartilage types, It mainly surrounds the blood vessels and nerves. 1. - It holds organ in place and attaches epithelial tissue to other underlying tissues. Areolar and adipose connective tissues also absorb the shocks to protect the internal body tissues. ? In summary, areolar tissue is tough, yet flexible, and comprises membranes. The difference between regular connective tissue and irregular connective tissue. Muscles are covered by layers of dense connective tissue. “Dense Connective Tissue.” Histology of Connective Tissues – 4 Available here. This tissue can withstand multidirectional forces and it is found in large connective tissue sheets. Irregularly arranged fibrous connective tissues are found in areas of the body where stress occurs from all directions, such as the dermis of the skin. 3. Presence of extracellular matrix with ground substances and fibres is the unique characteristic feature of this special tissue. Pigmented connective tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin. Dense Connective Tissue: The dense connective tissue mainly contains fibrocytes. Areolar tissue provides the support framework for epithelium. Tendons are an example of dense connective tissue. 1. What is the Difference Between Cuboidal and Columnar...

Dense Connective Tissue: Dense connective tissue produces tendon and ligaments by forming strong, rope-like structures. Side by Side Comparison – Loose vs Dense Connective Tissue in Tabular Form Thus, this is the summary of the difference between loose and dense connective tissue. Tendons are another structure produced by dense connective tissue to connect muscles to bones. Based on the types and relative abundance of cells as well as the organization of fibres and ground substances, connective tissue can be classified into several categories. ADIPOSE Ts SUDAN IV 29. 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. 2. They are somewhat less flexible than loose 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. (E) Mucoid Connective Tissue: In addition to above mentioned connective tissues, mucoid tissue occurs as a foetal or embryonic connective tissue. Besides, their location is also a distinct another difference between loose and dense connective tissue. Considering its structure and the wide variety of functions, the connective tissue is the most known diverse tissue out of all basic tissues. Tendons attach skeletal muscles to bones. They are spindle-shaped cells and are scattered mostly throughout the matrix. Fibres and fibroblasts are compactly arranged. Connective tissue, as the name implies, is a term given to several different tissues of the body that serve to connect, support and help bind other tissues in the body. The difference between regular connective tissue and irregular connective tissue. AREOLAR TISSUE 26. It consists of loosely arranged fibres and cells. Dense connective tissues are completely dominated by fibres. of loose and dense connective tissue, including areolar, adipose, reticular, tendons, ligaments, 09:01 dense irregular, and dense elastic tissue.

Accessed 10 Sept. 2017. Loose Connective Tissue: The three types of loose connective tissue are areolar, adipose, and reticular tissue. is how the fibers are arranged. Dense Connective Tissue: Dense connective tissue is a type of connective tissue that contains numerous collagen fibers and provides a strong connection between the tissues that mainly form the structural parts of the body. Elastic connective tissue is a modified dense connective tissue that contains numerous elastic fibers in addition to collagen fibers, which allows the tissue to return to its original length after stretching Figure 4.10). Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. The three types of loose connective tissue are areolar, adipose, and reticular tissues. There are three primary types of connective tissues and these are the proper connective tissues, supporting connective tissues, and fluid or liquid connective tissues. In loose connective tissue, the fibers are loosely organized, leaving large spaces in between. Another significant difference between loose and dense connective tissue is that loose connective tissue has more vessels than dense connective tissue. A connective tissue disease is any disease that affects the parts of the body that connect the structures of the body together. All rights reserved. Dr.Samanthi Udayangani holds a B.Sc. Since the loose and dense connective tissues are part of the connective tissue, people get confused regarding the main differences between them. AREOLAR TISSUE 25. The connective tissue can be classified into three categories. Hence, they are present in places where force is applied in one direction. Since the dense connective tissue is resistant to stretch, it provides strength to organs and tissues. The lungs and arteries have a layer of elastic connective tissue … There are four types of basic tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. 3. Loose connective tissue is a category of connective tissue which is abundant in our body and has a few fibres in the matrix while dense connective tissue is a type of connective tissue that has abundant fibres in the matrix. The structure of connective tissue varies from soft gel-like loose (areolar) connective tissue to hard bones. 1. In proper connective tissues, the matrix is soft, less rigid and shows varying degree of toughness. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue . Loose connective tissue is a category of connective tissue which includes areolar tissue, reticular tissue, and adipose tissue.Loose connective tissue is the most common type of connective tissue in vertebrates. Connective tissue mainly provides structural support to the soft organs. The key difference between loose and dense connective tissue is that loose connective tissue has loosely arranged fibres and cells in the matrix, while dense connective tissue has densely arranged fibres in the matrix. The dense connective tissue is classified based on the weave of the collagen fibers in the tissue. In dense irregular connective tissue the fibres do not show a clear orientation within the tissue but instead form a densely woven three-dimensional network. 2. On the basis of the … If it has a few fibers, it is loose. Therefore, the main difference between loose and dense connective tissue is the density of fibers in the extracellular matrix in each type of connective tissue. There are four types of basic tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. The dense elastic tissue is the only type of dense connective tissue that is elastic and it is mainly composed of elastin fibers. Tendons are an example of dense connective tissue. Loose irregular connective tissue includes, but is not limited to, the superficial fascial sheath of the body directly under the skin, the muscle and nerve sheaths, and the bed and framework of the internal organs. 1. To protect, support, insulate, and bind other tissues of the body. The three types of dense connective tissue are dense regular, dense irregular, and elastic tissues. 6. The dense irregular connective tissue contains collagen fibers that run in all directions. Connective tissue fills the surfaces between the other types of tissues in the body.
