Connective tissue (CT) is a one of the four main classes of tissues. Dense Regular Connective Tissue Densely packed collagen fibers running mostly in the same direction; fibroblasts wedged in-between fibers. 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. Common examples of connective tissues include tendons, adipose tissue, and cartilage. These three types of fibers are combined in different levels to produced connective tissue with different properties. DENSE REGULAR CONNECTIVE TISSUE The collagen fibers are present in rows between many parallel bundles of fibers. Location: Tendons, Ligaments, Aponeurosis (similar to tendons).

Dense regular connective tissue in which the extracellular fibers all run in the same direction and plane. There are 2 types of dense connective tissue: Dense Regular and Dense Irregular Connective Tissue. The common cell types in connective tissue include: fibroblasts, mast cells, plasma cells, macrophages, adipocytes, and leukocytes. Connective tissue proper includes loose connective tissue and dense connective tissue. Types of Connective Tissues. Areolar (loose) Connective Tissue. ligaments (which link bone to bone at joints) and tendons (connections between bones or cartilage and muscle). Others, such as bone, are richly supplied with blood vessels. Its cellular content is highly abundant and varied. To understand why connective tissue is so important, lets take a close look at the various kinds of connective tissue, along with some examples. FUNCTION • Attach muscle with bones or with others muscle and attach bone to bones. Type # 2. The paucity of cells, most of which are fibroblasts, may account for the slow healing of torn tendons. Dense irregular: Much of the dermis layer of the skin … Dense Irregular Connective Tissue: Dense Connective Tissue. e.g. Dense Connective Tissue Dense CT is characterized by large, robust collagen fibres that provide a considerable amount of strength to this tissue.

When it comes to cell type, the cells found in connective tissues depends on the type of tissue they support. Fibres are so numerous that the key identifying trait of this tissue is the absence of open spaces between cells or fibres. This type of tissue gives the walls of large arteries and respiratory passages strength … Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. Thin fibroblast processes with sparse cytoplasm are visible extending from the tips of the nuclei. This type of body tissue makes up the dermis — … Loose connective tissue (LCT), also called areolar tissue, belongs to the category of connective tissue proper. 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). Function: Dense irregular tissue functions to support tissues in multiple directions. There are three major categories of dense connective tissue: regular, irregular, and elastic. Bone is a specialized connective tissue type. Cartilage is avascular, while dense connective tissue is poorly vascularized.

Found in ligaments, tendons, and sheets of connective tissue (e.g. The latter is sub-divided into two categories — regular and irregular — that are classified based on the arrangement of the tissue's fibers. The achilles tendon must be strong. This is because the fibers run in multiple directions. The fibers are mainly composed of type I collagen.Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. connective tissue: A type of tissue found in animals whose main function is to bind, support, and anchor the body. A connective tissue has two elements and these are the cell and the matrix. Dense connective tissue provides strength to the tissue, and the tissue is less flexible. There are 2 types of dense connective tissue: Dense Regular and Dense Irregular Connective Tissue. In the dense connective tissue, fibroblast cells and fibres are compactly packed. reticular tissue function. Appearance: Fibers are “regular” in the sense that they all run parallel to each other or in the same direction. ; adipose tissue: Connective tissue that stores fat and cushions and insulates the body. Dense regular connective tissue: In this type of tissue, the collagen fibres are densely packed, and arranged in parallel. Dense regular: Tendons and ligaments are examples of dense regular connective tissue. cartilage - (see the topic on bone and cartilage) adipose tissue (see adipose cells) (1, 2, and 3) They produce both fibers and amorphous ground substance. Connective tissue in which there are relatively few fibers and lots of cells is loose connective tissue. Collagen Fibers: Dense regular connective tissue has dark staining collagen fibers. The type of connective tissue shown in this photograph is is a type of loose connective tissue. The major cell component is the fibroblast (also called tendinocyte; blue arrow).

Types of cells Extracellular matrix fibers Dense regular connective tissue Dense irregular connective tissue Type of dense connective tissue 18 3. 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. 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. 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. Instead of an aqueous extracellular matrix, the ground substance is mineralized and hard. cartilage: A type of dense, non-vascular connective tissue, usually found at the end of joints, the rib cage, the ear, the nose, in the throat, and between intervertebral disks. ... dense regular tissue location. In connective tissue, cells that secrete the proteins of the fibers. Dense connective tissue contains more collagen fibers than loose connective tissue. Dense connective tissue. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. The fibers are mainly composed of type I collagen. Although it is the most abundant and widely distributed of the primary tissues, the amount of connective tissue … Loose connective tissue is the most abundant type. They are somewhat less flexible than loose connective tissue. They include white fibrous tissues such as tendon and sheath and yellow elastic tissues such as the ligaments. It consists of loosely arranged fibres and cells. Dense connective tissue.

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. The ECM is composed of a moderate amount of ground substance and two main types of protein fibers: elastic and reticular fibers. It has both collagen and elastic fibers, which provide great tensile strength and elasticity in one direction. This tissue is composed primarily of collagen fibers, a few elastic fibers and a few fibroblasts. Highly flattened, heterochromatic fibroblast nuclei are interspersed with collagen bundles oriented in parallel. fasciae and aponeuroses). The composition of dense irregular is much like dense regular; it is the arrangement of the fibers that distinguishes these two tissue types. Post was not sent - check your email addresses! Whereas, dense connective tissue is less abundant, and it consists of many fibres in the matrix.
