Functions: The pigmented connective tissue gives colour to the structures. TENDON L.S. Connective tissue proper; Loose (areolar) connective tissue - highly cellular with a sparse, random arrangement of collagen fibers (and some elastic fibers) Dense connective tissue - collagen fibers with little ground substance; Dense regular connective tissue - collagen fibers oriented in the same direction Dense regular connective tissue provides connection between different tissues in the human body. It takes various forms as it supports, insulates, and protects the body. Connective tissue Adult Ordinary Loose Areolar Adipose Reticular Dense Regular Tendon Ligament Aponeurosis Irregular Subcutaneous tissue Specialized Blood Cartilage Bone Fetal 24. Dense connective tissue is divided into 1) dense regular, 2) dense irregular, 3) elastic. It is customary to describe dense conective tissue as "irregular" or "regular". AREOLAR TISSUE 26. The cells sit in a matrix made up of glycoproteins, fibrous proteins and glycosoaminoglycans , which have been secreted by the fibroblasts, and the major component of the matrix, is in fact, water. Reticular layer : Dense irregular connective tissue. Connective tissue can be classified as loose or dense. Medimolt describe about connective tissue. Function of Dense Regular Connective Tissue:-Tightly bind body parts. Dense connective tissue contains more collagen fibers than loose connective tissue. ADIPOSE TISSUE 27. Dense Irregular Connective Tissue Definition. General connective tissue is either loose, or dense, depending on the arrangement of the fibres. In the knee, these bones are the femur and tibia. They provide internal support as well as give and maintain form to the body. Dense connective tissue. Dense regular connective tissue: In this type of tissue, the collagen fibres are densely packed, and arranged in parallel. (E) Mucoid Connective Tissue: In addition to above mentioned connective tissues, mucoid tissue occurs as a foetal or embryonic connective tissue. As the name suggests a connective tissue acts as a connecting medium, with some specialized functions. 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. reticular. Connective tissue includes several types of fibrous tissue that vary only in their density and cellularity, as well as the more … Location of Dense Regular Connective Tissue:-Tendons-Ligaments. 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. Characteristics of Dense Irregular Connective Tissue:-Dense connective tissue-Fluid-gel matrix-Random collagen fibers. Functions of connective tissue; 1. Dense regular connective tissue The fibers of this tissue are tightly packed into par­allel bundles, between which are a few highly attenuated, spindle-shaped fibroblasts. Dense regular connective tissue is composed of fibroblasts that excrete high amounts of collagen fibers. Dense Connective Tissue: The three types of dense connective tissue are dense regular, dense irregular, and elastic tissue. It provides strong attachment between different structures. The latter is sub-divided into two categories — regular and irregular — that are classified based on the arrangement of the tissue's fibers. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis. ADIPOSE TISSUE 28. The small, cigar-shaped nuclei of the fibroblasts are oriented parallel to the fibers; the cytoplasm is difficult to … Transporting fluids and dissolved materials. Dense connective tissue, also called dense fibrous tissue, forms the body’s tendons, ligaments, joint capsules, and aponeuroses, as well as the dermis of the skin. Dense connective tissue contains more collagen fibers than does loose connective tissue. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane.

Connective tissue is present throughout the human body and serves a variety of crucial functions beyond connecting body parts. In animals, the connective tissue is very complex has a vital role. AREOLAR TISSUE 25. 31. Tendons are dense connective tissues that join muscle to bone and play a vital role in overall joint stability and function. It is also in the sclera and in the deeper skin layers. Protecting delicate organs. Papillary layer : Loose connective tissue. Connective tissue, group of tissues that maintain the form of the body and its organs and provide cohesion and internal support. 4. Our skin has two principal layers : epidermis and dermis. If the matrix consist mainly of collagen, it provides great tensile strength and can withstand tremendous pull in the direction that the fibers run without stretching. Other types include epithelial tissue, muscle tissue, and nervous tissue.They are developed from the mesoderm.Connective tissues are present in between another type of tissues that establish … Dense Connective Tissue. Like many other joints in the body, the knee has a dense, fibrous, connective tissue that seals the joint space between the bones. Collagen type I fibrils are described as long crystals that are arranged in an anisotropic fashion [1–8].These collagen fibrils are organized into primary, secondary, and tertiary bundles, responsible for the mechanical resilience of the tissue (Table 1). As a consequence, it displays greater resistance to stretching and a higher tensile strength. TENDON L.S. Dense Irregular Connective Tissue. Function Loose Connective Tissue: The major function of the loose connective tissue is to serve as a supporting matrix for the blood vessels, lymphatic vessels, nerves, muscle fibers, organs, and the skin. Dense irregular CT is used to form the capsules that surround our internal organs such as the pericardium or the renal capsule. The collagen fibers are densely packed together and arranged in parallel to each other. Let us learn about some connective tissues - … Dense connective tissue is dense because of the high proportion of fibers that run parallel to each other. ADIPOSE Ts SUDAN IV 29. Dense regular connective tissue. 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. The collagen fibers travel in all directions which is vital to this tissue's function. As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. Regular fibrous connective tissue, shown in the figure below, is found in tendons (which connect muscles to bones) and ligaments (which connect bones to … Key Difference – Dense Regular vs Dense Irregular Connective Tissue. Dense regular connective tissue in which the extracellular fibers all run in the same direction and plane. Function. Helps to provide structural strength. Connective tissue provides support to the organs and tissues of the body and is separated into two types: loose connective tissue, which is more abundant, and dense connective tissue. ligaments (which link bone to bone at joints) and tendons (connections between bones or cartilage and muscle). Finden Sie perfekte Stock-Fotos zum Thema Dense Regular Connective Tissue sowie redaktionelle Newsbilder von Getty Images. Dense regular tissue is found in tendons, ligaments, and muscle fascia. The epidermis is composed of epithelial tissue, and the dermis is connective tissue. Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. Dense connective tissue can be characterized as regular or irregular on the basis of fiber arrangement. Dense regular connective tissue is also known as Regular Fibrous Connective Tissue and it is a type of general connective tissues consisting of type I collagen bundles that are arranged according to a definite pattern in which the fibers and fibroblasts align parallel to prolonged resistant forces that are exerted in the same direction. The dermis supports the epidermis and binds it to the subcutaneous tissue (hypodermis), the loose connective tissue directly under the skin. Key: Collagen fibers cut longitudinally (along the length of the fiber) Collagen fibers cut transversely (across the width ... Function: Able to withstand tension applied from many different directions. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. This type of tissue gives the walls of large arteries and respiratory passages strength and the … From the functional viewpoint it must be understood that even in "irregular" dense connective tissue, the collagen bundles are arranged to resist stretching in specific directions, and though the fibre bundles appear to run haphazardly, there is "order in the madness". The functions of areolar connective tissue include the support and binding of other tissues. There are three major categories of dense connective tissue: regular, irregular, and elastic. Loose connective tissue has relatively fewer cells and fibers per area than dense connective tissue, in which the cells and fibers are tightly packed. 30. e.g. 2. It has both collagen and elastic fibers, which provide great tensile strength and elasticity in one direction. This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. Forms tendons, ligaments and aponeuroses. It is further classified relative to function and by the type of fibers present. Pigmented connective tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin. Areolar Connective Tissue. Dense irregular connective tissue is a type of general connective tissue that is mostly composed of densely packed type 1 collagen fibers in diverse orientations with much less ground substance and sparse fibrocytes. Among the four main basic types of animal tissues, connective tissue is one of the major types present. 3. Dense connective tissue Dense regular tissue:- consist of collagen fibers regularly arranged in bundle and the matrix present is shiny white and fibroblasts are also present. Dense regular connective tissue is mainly made up of type I collagen fibers. In this post write about what is connective tissue, their classification, structure, location and function.. connective tissue basically five types - loose connective tissue, dense connective tissue, skeletal connective tissue, vascular connective tissue and muscular connective tissue.
