Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. Dense regular connective tissue (green square) consists of bundles of parallel collagen fibers (yellow arrow). As with dense regular connective tissue, when elastic fibers running in random directions outnumber collagen fibers, the tissue is a dense irregular elastic connective tissue.

Appearance: Fibers are “irregular” in the sense that they run in multiple directions. Function: Attaches muscles to bones or to other muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction. Fibres are so numerous that the key identifying trait of this tissue is the absence of open spaces between cells or fibres. Location: Dermis, fibrous capsules, fascia (periosteum and pericondrium). They are mostly located in the dermis layer of … The latter is sub-divided into two categories — regular and irregular — that are classified based on the arrangement of the tissue's fibers. Type # 2. Dense Regular Connective Tissue Primarily parallel collagen fibers; a few elastic fibers; major cell type is the fibroblast. Dense Connective Tissue: It is of two types; dense regular connective tissue and dense irregular connective tissue. The matrix is a substance in which the cells are embedded. Dense Regular Appearance : Fibers are “regular” in the sense that they all run parallel to each other or in the same direction. Dense regular connective tissue is mainly made up of type I collagen fibers. Function: Dense irregular tissue functions to support tissues in multiple directions. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. They are somewhat less flexible than loose connective tissue. The composition of dense irregular is much like dense regular; it is the arrangement of the fibers that distinguishes these two tissue types. Location: Tendons, Ligaments, Aponeurosis (similar to tendons). Loose connective tissue is the most abundant type. DENSE REGULAR CONNECTIVE TISSUE The collagen fibers are present in rows between many parallel bundles of fibers. Dense regular connective tissue in which the extracellular fibers all run in the same direction and plane. It is further classified relative to function and by the type of fibers present.

Connective tissue proper includes loose connective tissue and dense connective tissue. There are seven types of connective tissues found in the body of people. Used where strength of attachment is important, especially when stress will be along a predictable line. Cloudflare Ray ID: 6172e2428e33747e This tissue is composed primarily of collagen fibers, a few elastic fibers and a few fibroblasts. Dense connective tissue is another type of connective tissue proper that contains more fibers and the fibers are thicker and more densely packed with considerably fewer cells than in loose connective tissue. • Greatly stand stress when pulling force but only in … These three types of fibers are combined in different levels to produced connective tissue with different properties. Your IP: 132.148.182.88 The other specialised types of connective tissue are covered in other topics. connective tissue: A type of tissue found in animals whose main function is to bind, support, and anchor the body. This type of tissue gives the walls of large arteries and respiratory passages strength … If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Connective tissue is distinguished from the other types in that the extracellular material (matrix) usually occupies more space than the cells do, and the cells are relatively far apart. Dense connective tissue is reinforced by bundles of fibers that provide tensile … From Wikipedia, the free encyclopedia Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. Dense connective tissue contains more collagen fibers than loose connective tissue. Explore the 3D anatomical views in Modules 4.11 Special Connective Tissue: Bone and Cartilage and 4.13 Cartilage to learn about where bone and cartilage can be found in the body. Their main function is to support and transmit mechanical forces. The achilles tendon must be strong. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance.
The major cell component is the fibroblast (also called tendinocyte; blue arrow). There are 2 types of dense connective tissue: Dense Regular and Dense Irregular Connective Tissue. Slide 13 Trachea. 3 epithelial cells squamish , cubocial, and columnar. fat cells. For example, if a tissue has more elastin it will be stretchy. Instead of an aqueous extracellular matrix, the ground substance is mineralized and hard. Inactive fibroblasts are the predominate cell type in an adult tendon, which is classified as dense regular connective tissue. They can also be regular and irregular dense connective tissues. Thin fibroblast processes with sparse cytoplasm are visible extending from the tips of the nuclei. In the dense connective tissue, fibroblast cells and fibres are compactly packed. They include white fibrous tissues such as tendon and sheath and yellow elastic tissues such as the ligaments. Dense connective tissue has the same makeup as loose connective tissue except there is less space occupied by cells, and more densely packed with fibers. Types of Dense Connective Tissue Simplified, Can Synesthesia Reveal We Dont See The Same Colors. The fibers are mainly composed of type I collagen. Collagen Fibers: Dense regular connective tissue has dark staining collagen fibers. To understand why connective tissue is so important, lets take a close look at the various kinds of connective tissue, along with some examples. ... loose connective tissue types. Post was not sent - check your email addresses! Found in ligaments, tendons, and sheets of connective tissue (e.g. Performance & security by Cloudflare, Please complete the security check to access. It can be a fluid, semi-fluid, a ground substance, a gelatinous one, or a protein fiber.

FUNCTION • Attach muscle with bones or with others muscle and attach bone to bones. The collagen fibers are densely packed together and arranged in parallel to each other. These are: Areolar Connective Tissue; Adipose Tissue; Dense Irregular Tissue; Dense Regular Tissue; Cartilages; Bones; Blood; 1. It contains collagen fibres, fibroblasts and adipocytes (these cells are 'empty looking' as the process of making the stained section extracts the lipid from these cells). In many sources, this type is listed as connective tissue proper; however, it is found in specific locations and can fit into either category. They produce both fibers and amorphous ground substance. Dense irregular: Much of the dermis layer of the skin … Highly flattened, heterochromatic fibroblast nuclei are interspersed with collagen bundles oriented in parallel. The common cell types in connective tissue include: fibroblasts, mast cells, plasma cells, macrophages, adipocytes, and leukocytes. When it comes to cell type, the cells found in connective tissues depends on the type of tissue they support. Dense irregular connective tissue features the same basic structures as dense regular connective tissue, but its collagen fibers are irregularly arranged bundles and are significantly thicker than those of the regular variety. This is because the fibers run in multiple directions. (A) Dense Regular Connective Tissue: In the dense regular connective tissue, the collagen fibres are present in rows between many parallel bundles of fibres. Types of Connective Tissues. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis.
