This video explains how dense connective tissue differs from loose connective tissue. Dense connective tissue has two further subdivision, Dense regular connective tissue, and Dense irregular connective tissue. Connective tissue is one of the basic animal tissue. Dense regular connective tissue comprises structures such as ligaments and tendons, whilst dense irregular tissue is more widely distributed throughout the body. Dense regular connective tissue is a type of connective tissue in which collagen fibers are arranged parallel in the form of a bundle. Two types of connective tissues can be found such as dense regular and dense irregular. The difference between regular connective tissue and irregular connective tissue. 1. It could be classified into two sub types of connective tissues namely; dense regular white fibrous connective tissue and dense regular yellow fibrous connective tissue. Available here, 1.’411 Reg Dense-Irregular Dense’By OpenStax College – Anatomy & Physiology, Connexions Web site. In dense connective tissue, the nuclei will usually be outside the fibers. Dense regular connective tissue, in which there are regularly arranged bundles packed with fibers running the same way in one direction, makes up tendons, which connect muscles to bones, and ligaments, which connect bones to bones. Dense irregular connective tissue is another type of connective tissues in which collagen fibers are arranged irregularly. This is the border of smooth muscle and dense irregular connective tissue. Connective tissues are present in between another type of tissues that establish connections between them. Areolar tissue IS fibrous connective tissue, but there are also other kinds—reticular, dense irregular, and dense regular fibrous connective tissues. In dense regular connective tissue, collagen fibers are arranged parallel to each other in the form of a bundle that is arranged in a specific orientation. Dense irregular connective tissue Dense regular connective tissue forms tendons (seen here) and ligaments. However, they are organized differently. 6. dense irregular connective tissue; SPECIALISED CONNECTIVE TISSUES. makes up tendons, ligaments, sclera of eye.

They are developed from the mesoderm. tissue able to withstand tension from many directions. Dense regular connective tissue comprises structures such as ligaments and tendons, whilst dense irregular tissue is more widely distributed throughout the body. The main distinction between the two is the fact that in dense irregular connective tissues the fibres are arranged without any specific direction, whereas, in dense regular connective tissues the fibres are arranged in one direction clearly parallel to each other. Dense connective tissue is often further divided into two main categories; dense irregular connective tissue and dense regular connective tissue. Similarities Between Dense Regular and Dense Irregular Connective Tissue A typical connective tissue consists of three main components which include fibers, ground substance, and cells. In dense regular connective tissue, the collagen fibers are present in rows between many parallel bundles of fibers. Type I collagen fiber bundles composing dense irregular connective tissue Dermis Epidermis Rete pegs Dermal papilla Epithelium is avascular and must get its nourishment (oxygen, nutrients, and metabolites) from that diffused through the blood capillaries located in the underlying connective tissue. The fibers consist of elastin and collagen fibers. Dense regular connective tissue: Dense irregular connective tissue : In this tissue, collagen fibres are present in a regular manner: In this tissue, collagen fibres are found irregularly : These are found in tendons and ligaments: These are found in the skin. 2.Dense Irregular Connective Tissue, histologyolm.stevegallik.org/node/103. Both tissues establish connections between different tissues. The latter is sub-divided into two categories — regular and irregular — that are classified based on the arrangement of the tissue's fibers. Fibers could be stretched in many different directions in dense irregular connective tissue. 1)Dense irregular is not dark-staining, 2)the collagen fibers aren't parallel. Therefore, these connective tissues are present in structures that require higher mechanical strength. Figure 01: Dense Regular Connective Tissue of the Tendon. These connective tissues are specialized to protect the skin by making the skin resistant to tearing due to the application of higher forces from different directions. Dense Connective Tissue: It is of two types; dense regular connective tissue and dense irregular connective tissue. Degree in Plant Science, M.Sc. Connective tissues that possess a large quantity of collagen fibers often provide the framework for organs such as the spleen and lymph nodes. The eosinophilic collagen of the dense regular connective tissue and the fibrocartilage is regular and densely packed. 3. Periosteum and perichondrium could be included as other examples for this type of connective tissue. 5)It provides connections between bone-to-bone and muscle-to-bone. However, not all connections are by dense regular connective tissues. The dense irregular connective tissue contains collagen fibers that run in all directions. Connective Tissue Definition. ... dense irregular connective tissue function. Other types include epithelial tissue, muscle tissue, and nervous tissue. The three types of dense connective tissue are regular, irregular, and elastic tissue. Dense regular connective tissue is found in tendons and ligaments. Please download PDF version here Difference Between Dense Regular and Irregular Connective Tissue, 1.Study.com, Study.com. They fill the spaces between organs and tissues by providing structural and mechanical support. In dense connective tissue, the nuclei will usually be outside the fibers. It is also in the sclera and in the deeper skin layers. 4)Dense regular can be found in ligaments and tendons (i.e. In dense irregular connective tissue, collagen fibers are arranged irregularly as the name itself suggests. Figure 02: Dense Irregular Connective Tissue.

Side by Side Comparison – Dense Regular vs Dense Irregular Connective Tissue in Tabular Form The eosinophilic collagen of the dense regular connective tissue and the fibrocartilage is regular and densely packed. This type of connective tissue is present where force is applied for stretching of different tissues where they could be extended and return to the same level as before without causing any damage. Dense regular connective tissue provides connection between different tissues in the human body. In yellow fibrous connective tissue, elastic fibers are present as the dominant content. ... dense irregular connective tissue function. is how the fibers are arranged. FALSE; possess a large quantity of reticular fibers The basic difference between dense irregular and dense regular connective tissues is in the amount of elastic fibers and adipose cells present. Remember that smooth and skeletal muscle "fibers" are cells, while connective tissue "fibers" are cables of acellular collagen. Dense regular connective tissue (DRCT) is divided into white fibrous connective tissue and yellow fibrous connective tissue, both of which occur in two forms: cord arrangement and sheath arrangement. 3.Paxton, Steve, et al. Other than the dermis of the skin, the dense irregular connective tissue is present in the submucosa of the digestive tract, fibrous capsule present in the joints and the lymph. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Remember that smooth and skeletal muscle "fibers" are cells, while connective tissue "fibers" are cables of acellular collagen. It forms structures like tendons in which the forces are directed in a single direction. Dense regular has dark-staining collagen fibers that run parallel to each other. The collagen fibers … 1 0 obj In addition, they perform the work of connecting the body tissue, cell, and organs. This is happens as a result of the collagen fibers which are present in higher quantities. Dense regular connective tissue provides for strong attachment between various structures. White fibrous connective tissue consists of a higher proportion of white inelastic fibers when compared with elastic fibers. Connective tissues are present in between another type of tissues that establish connections between them. The other specialised types of connective tissue are covered in other topics. In dense irregular connective tissue, the fibres have no specific direction of the arrangement. makes up tendons, ligaments, sclera of eye. Dense regular connective tissue, in which there are regularly arranged bundles packed with fibers running the same way in one direction, makes up tendons, which connect muscles to bones, and ligaments, which connect bones to bones. endobj Its collagen bundles are all oriented in parallel and the fibroblasts are also dispersed in rows between the collagen. Mostly these types of connective tissues are found in tendons and ligaments. Function. It provides connections between bone-to-bone and muscle-to-bone, and it is strong and can stand great tensile stress.
