This tissue can withstand multidirectional forces and it is found in large connective tissue sheets. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. Loose Connective Tissue: Loose connective tissue consists of loosely arranged fibers. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } - It holds organ in place and attaches epithelial tissue to other underlying tissues. If it has a lot of fibers, it is dense. ADIPOSE TISSUE 28. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue . The difference between regular connective tissue and irregular connective tissue. In dense irregular connective tissue, the fibres have no specific direction of the arrangement. Loose connective tissue consists of a sparse extracellular matrix of hyaluronan and proteoglycans supported by a few collagen fibrils and elastic fibrils. TENDON L.S. 30. The tissue is also found around and between most body organs. 2019. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. It mainly surrounds the blood vessels and nerves. Dense routine connective tissue is identified by an abundance of securely loaded collagen fibers and fairly couple of cells The collagen fibers exist in big packages that are “frequently” set up, indicating they are normally parallel to each other. What is the Difference Between Loose and Dense Connective Tissue       – Comparison of Key Differences, Key Terms: Adipose, Areolar, Collagen, Dense Connective Tissue, Dense Irregular, Dense Regular, Elastin, Loose Connective Tissue, Reticular. They are spindle-shaped cells and are scattered mostly throughout the matrix. Reticular, collagen, and elastin are the three types of protein fibers that specifically occur in the connective tissue. That means dense connective tissue consists of numerous protein fibers in the matrix. TENDON L.S. Dense Connective Tissue: The dense connective tissue mainly contains fibrocytes. Fibroblasts are widely dispersed in the loose connective tissue, secreting protein fibers and proteoglycans to the extracellular matrix. Pigmented connective tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin. The three types of dense connective tissue are regular, irregular, and elastic tissue. Dense connective tissue (dense regular, dense irregular, and elastic) What is the primary function of connective tissue? The three types of loose connective tissue are areolar, adipose, and reticular tissues. Areolar and adipose connective tissues also absorb the shocks to protect the internal body tissues. ADIPOSE Ts SUDAN IV 29. The dense connective tissue is classified based on the weave of the collagen fibers in the tissue. – Attaches epithelium to the underlying tissues, – Provides oxygen and nutrients to the epithelium, – Forms the structural framework of the soft organs. The three types of loose connective tissue are areolar, adipose, and reticular connective tissue. Vipin Sharma Biology Blogs for more information regarding every national level competitive exam in which biology is a part . The dense connective tissues are then classified into two groups known as dense irregular connective tissue and dense regular connective tissue. “Dense connective tissue-400x” By J Jana – Own work (CC BY-SA 4.0) via Commons Wikimedia, Filed Under: Biology Tagged With: Dense Connective Tissue, loose connective tissue. The reticular connective tissue forms the framework around organs, glands, and the lymph nodes. Compare the Difference Between Similar Terms. The dermis of the skin is composed of loose connective tissue interfacing with an underlying dense irregular connective tissue. Functions: The pigmented connective tissue gives colour to the structures. They are somewhat less flexible than loose connective tissue. Characteristics. Thus, this is the summary of the difference between loose and dense connective tissue. Loose (areolar connective tissue) is the most abundant form of collagenous connective tissue. The areolar tissue and the adipose tissue are classified under the loose connective tissue. In addition to fibroblasts, the cell population is heterogeneous, including both indigenous and emigrant connective tissue cells (see Fig. The main difference between loose connective tissue and dense connective tissue is that loose connective tissue consists of protein fibers packed with spaces whereas dense connective tissue consists of tightly packed protein fibers. Their main function is to support and transmit mechanical forces. Loose connective tissue is named as such due to the loose arrangement of fibres and cells in the matrix. If it has a lot of fibers, it is dense. They are somewhat less flexible than loose connective tissue. Besides, their location is also a distinct another difference between loose and dense connective tissue. Dense connective tissue is reinforced by bundles of fibers that provide tensile … 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. Depending on the arrangement of fibres, dense connective tissue exists in two distinct forms: dense irregular connective tissue and dense regular connective tissue. Also, dense regular tissue has further two types as dense collagenous connective tissue and dense elastic connective tissue. Loose connective tissue (areolar, adipose, reticular) 2. The main fiber component of the dense connective tissue is the collagen fibers. Side by Side Comparison – Loose vs Dense Connective Tissue in Tabular Form It is usually located under the epithelia; which is the outer covering of the blood vessel including the esophagus, fascia between muscles, pericardial sacs, and other organs of the body. It also helps to supply nutrients and oxygen to the epithelial tissue. Fibroblasts lie in rows between the collagen packages. Accessed 10 Sept. 2017. Loose connective tissues are present beneath the epithelial tissue that lines the internal body surfaces, glands, and around small vessels. This video explains how dense connective tissue differs from loose connective tissue. “411 Reg Dense-Irregular Dense” By OpenStax College – Anatomy & Physiology, Connexions Web site. In loose connective tissue, the fibers are loosely organized, leaving large spaces in between. 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. A connective tissue disease is any disease that affects the parts of the body that connect the structures of the body together. The location and the function of each type of loose connective tissue are described in table 1. 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. 28.1). In the dense connective tissue, fibroblast cells and fibres are compactly packed. Tendons are an example of dense connective tissue. Dense Connective Tissue. The loose connective tissue is more cellular, with smaller caliber collagen and elastic fibers than the coarser, dense irregular connective tissue. Another significant difference between loose and dense connective tissue is that loose connective tissue has more vessels than dense connective tissue. Since the loose and dense connective tissues are part of the connective tissue, people get confused regarding the main differences between them. Tendons attach skeletal muscles to bones. 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. Loose connective tissue and dense connective tissue are the two types of connective tissues in the body. However, it consists of many cells. Muscles are covered by layers of dense connective tissue. 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..
