dense regular elastic connective… Connective tissue cells. •Relate the functions of each connective tissue to their structural organization. Alpha units wrapped tight around each other, forming a fibril. Types of Connective Tissues. Dense connective tissue is often seen as the capsules enclosing organs and, in particular, tubular structures, but is most strikingly characterized in its appearance as tendons and ligaments. Dense regular connective tissue occurs where strong, flexible support is needed Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. dense regular collagenous connective tissue?c. In addition, they perform the work of connecting the body tissue, cell, and organs. Dense irregular connective tissue consists of tightly packer collagen fibers that appear less organized and less uniform that dense regular connective tissue tissue. Click here to find out more about the three different types of connective tissue.. Collagenous fibers. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers. 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. DENSE 2.1. Types of Collagen. Connective tissue: Connective tissues are the most abundant and widely distributed tissue in the body. Inactive fibroblasts are the predominate cell type in an adult tendon, which is classified as dense regular connective tissue. • In contrast, dense regular connective tissue contains densely packed collagen fibers that exhibit a regular and parallel arrangement. 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). All of these cells are developed during the embryonic life from the mesenchyme of the mesodermal layer of the embryonic germ layers. Then, many layers of fibrils form collagen. An example of regular dense connective tissue is that of tendons; an example of irregular dense connective tissue is that of the dermis. Dense regular connective tissue contains a predominance of collagen fibers than that of loose connective tissue which has a predominance of cellular contents. 4. All connective tissues consist of two basic elements: cells and _____. Create a table with the tissue type, what cells are found in that tissue type, what fibers are found in that tissue and what is the function of each fiber type, and briefly explain the matrix of that tissue. To define fibrous connective tissue, you normally separate it into two categories: regular and irregular. Cells of connective tissues. The nuclei in this tissue are stretch long and the tissue may appear wavy under a microscope. 1000x . C. loose, dense connective, dense regular, and dense irregular tissue. - Found beneath the epidermis layer and is also underneath the epithelial tissue 2. The dense irregular connective tissue contains collagen fibers that run in all directions. Areolar (loose) Connective Tissue. The three types of dense connective tissue are regular, irregular, and elastic tissue. 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. Space between the cells; a substance produced and secreted by connective tissues; composition differs with each type of tissue and consists of fibers and ground substance . Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. The membrane capsule surrounding several organs is also dense irregular tissue. Matrix: Also known as the ground substance. 3. Highly flattened, heterochromatic fibroblast nuclei are interspersed with collagen bundles oriented in parallel. 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. It has less fibrous tissue. The connective tissue is the glue that holds all other tissues together, it has the important function of ensuring that our body systems work in harmony. The dense regular connective tissue contains parallelly arranged collagen fibers in a single direction. It forms structures like tendons in which the forces are directed in a single direction. fibroblasts, macrophages, leukocytes, plasma cells, mast cells, and adipose cells. The ground substances are little and only found around the chondrocytes. It consists of regular parallel bundles of collagen fibers separated by encapsulated chondrocytes that occur singly, in pairs or sometimes form rows. D.... Posted one year ago. Loose and dense connective tissues differ from each other by the ratio of ground substance to fibrous tissue. In both connective tissue types, fibroblasts are the most abundant cells, which are located between the dense collagen bundles. B. bone, cartilage, glands, and adipose tissue. Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. Dense connective tissue Slide 15 Elastic connective tissue Slide 28 Mucus connective tissue Slide 87 . In this assignment I?m going to talk about the structure of the main tissues which are found within. Dense connective tissue contains more collagen fibers than does loose connective tissue. Loose connective tissue, also called areolar connective tissue, has a sampling of all of the components of a connective tissue. Connective tissue connects, separates & supports all other types of tissues in the body, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). There are three major categories of dense connective tissue: regular, irregular, and elastic. Loose connective tissue has some fibroblasts, although macrophages are present as well. Distinguish between loose irregular (areolar), dense irregular, or dense regular connective tissues on the basis of fiber packing and orientation. In regular dense connective tissue, the fibers are arranged in parallel bundles, and are often white or yellow colored. Connective tissue cells originate from the undifferentiated mesenchymal cells while others from hemopoietic stem cells. Dense connective tissue is again can be divided into two types dense regular and dense irregular connective tissues. The type of connective tissue shown in this photograph is is a type of loose connective tissue. Loose connective tissue Dense connective tissue (regular and irregular) Specialized connective tissues: Cartilage Bone Adipose Blood : For more details about connective tissue, take a look at the following study unit: Cells and tissues Explore study unit Characteristics. Fibroblasts are the primary cells present and they occur in rows parallel to the bundles of collagen fibers. Thin fibroblast processes with sparse cytoplasm are visible extending from the tips of the nuclei. Dense regular: Tendons and ligaments are examples of dense regular connective tissue. Loose connective tissue (LCT), also called areolar tissue, belongs to the category of connective tissue proper. Dense connective tissue is enriched in collagen fibers with little ground substance. 8. Is the dense fibrous connective tissue matrix made by cells? These are basically dense masses of collagenic fibers and fibroblasts arranged in an orderly manner, with the cells and fibers being oriented in the same direction (i.e. As a consequence, it displays greater resistance to stretching. Because this tissue is silvery white in appearance, it is sometimes called white fibrous connective tissue. Ligaments are a second type of regular dense connective tissue. What’s Inside Connective Tissue . This type of tissue is found in the tendons and ligaments. When a connective tissue has a high concentration of cells or fibers, it has a proportionally-less-dense matrix. Identify, at the light and electron microscopic levels, collagen, reticular, and elastic fibers. Dense irregular: Much of the dermis layer of the skin is composed of dense irregular connective tissue. There are seven types of connective tissues found in the body of people. CONNECTIVE TISSUE by Syahifa Najiha 1. If the closely packed bundles of fibers are located in one direction, it is called regular; if oriented in multiple directions, it is referred to as irregular. - It holds organ in place and attaches epithelial tissue to other underlying tissues. Matrix. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. Dense regular connective tissue is characterized by large amounts of densely packed collagenous fibers that run parallel to the direction of force placed on the tissue during body movement. Connective tissues contains a matrix and 3 types of fibers fibers. The major cell on dense irregular connective tissue is the fibroblasts. These are: Areolar Connective Tissue; Adipose Tissue ; Dense Irregular Tissue; Dense Regular Tissue; Cartilages; Bones; Blood; 1. -It plays a significant role in the diffusion of gases, nutrients and metabolic wastes between the cells and the vessels that perfuse the tissue. This type of tissue gives the walls of large arteries and respiratory passages strength and the ability to regain original shape after stretching. Loose connective tissue is full of ground substance.
