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. Types of Connective Tissues. Connective tissue cells originate from the undifferentiated mesenchymal cells while others from hemopoietic stem cells. Loose connective tissue, also called areolar connective tissue, has a sampling of all of the components of a connective tissue. Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. d. extracellular matrix. Dense connective tissue contains more collagen fibers than does loose connective tissue. Connective tissues contains a matrix and 3 types of fibers fibers. Alpha units wrapped tight around each other, forming a fibril. 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 . All of these cells are developed during the embryonic life from the mesenchyme of the mesodermal layer of the embryonic germ layers. This type of tissue is found in the tendons and ligaments. 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. B. bone, cartilage, glands, and adipose tissue. Dense irregular: Much of the dermis layer of the skin is composed of dense irregular connective tissue. Solution for What is the primary component in:a. loose connective tissue?b. • In contrast, dense regular connective tissue contains densely packed collagen fibers that exhibit a regular and parallel arrangement. dense regular elastic connective… This tissue has very few fibroblasts and almost no other cells. Connective tissue consists of cells that are often characteristic of a particular type of connective tissue. a. collagen fibers b. chondrocytes c. adipose tissue d. extracellular matrix e. reticular fibers. Loose connective tissue has some fibroblasts, although macrophages are present as well. Inactive fibroblasts are the predominate cell type in an adult tendon, which is classified as dense regular connective tissue. As a consequence, it displays greater resistance to stretching. Dense regular: Tendons and ligaments are examples of dense regular connective tissue. Connective tissue cells. C. loose, dense connective, dense regular, and dense irregular tissue. All connective tissues consist of two basic elements: cells and _____. It forms structures like tendons in which the forces are directed in a single direction. It is a transitional form between hyaline cartilage and dense regular connective tissue. Then, many layers of fibrils form collagen. Collagen . The ground substances are little and only found around the chondrocytes. There are seven types of connective tissues found in the body of people. It has less fibrous tissue. Connective Tissue Cells. Dense connective tissue is again can be divided into two types dense regular and dense irregular connective tissues. This type of tissue gives the walls of large arteries and respiratory passages strength and the ability to regain original shape after stretching. Made of . Dense irregular connective tissue consists of tightly packer collagen fibers that appear less organized and less uniform that dense regular connective tissue tissue. 4. 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). CONNECTIVE TISSUE by Syahifa Najiha 1. Identify and list the cell types found in the various kinds of general connective tissues, and describe their origins and functions. The membrane capsule surrounding several organs is also dense irregular tissue. D.... Posted one year ago. What’s Inside Connective Tissue . The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. Dense connective tissue forms strong, rope-like structures such as tendons and 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. In addition, they perform the work of connecting the body tissue, cell, and organs. Dense regular connective tissue provides connection between different tissues in the human body. fibroblasts, macrophages, leukocytes, plasma cells, mast cells, and adipose cells. Objectives •Describe each type of connective tissue (CT) and explain where they are found. 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. - It holds organ in place and attaches epithelial tissue to other underlying tissues. Matrix. There are three major categories of dense connective tissue: regular, irregular, and elastic. The three types of dense connective tissue are regular, irregular, and elastic tissue. The type of connective tissue shown in this photograph is is a type of loose connective tissue. Loose connective tissue (LCT), also called areolar tissue, belongs to the category of connective tissue proper. 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. Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. Dense regular connective tissue is found in tendons and ligaments. The dense irregular connective tissue contains collagen fibers that run in all directions. - Found beneath the epidermis layer and is also underneath the epithelial tissue 2. Identify, at the light and electron microscopic levels, collagen, reticular, and elastic fibers. •Relate the functions of each connective tissue to their structural organization. Dense Regular CT. Function: Make up: Elastic Connective Tissue. 1000x . Ligaments are a second type of regular dense connective tissue. Collagenous fibers. In regular dense connective tissue, the fibers are arranged in parallel bundles, and are often white or yellow colored. Loose and dense connective tissues differ from each other by the ratio of ground substance to fibrous tissue. To define fibrous connective tissue, you normally separate it into two categories: regular and irregular. 8. It has both collagen and elastic fibers, which provide great tensile strength and elasticity in one direction. Types of Collagen. Dense connective tissue is enriched in collagen fibers with little ground substance. An example of regular dense connective tissue is that of tendons; an example of irregular dense connective tissue is that of the dermis. The major cell on dense irregular connective tissue is the fibroblasts. Dense regular connective tissue occurs where strong, flexible support is needed 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. Cells of connective tissues. 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. Thin fibroblast processes with sparse cytoplasm are visible extending from the tips of the nuclei. The fibers are mainly composed of type I collagen. In this assignment I?m going to talk about the structure of the main tissues which are found within. It consists of regular parallel bundles of collagen fibers separated by encapsulated chondrocytes that occur singly, in pairs or sometimes form rows. Because this tissue is silvery white in appearance, it is sometimes called white fibrous connective tissue. When a connective tissue has a high concentration of cells or fibers, it has a proportionally-less-dense matrix. Loose connective tissue is full of ground substance. The nuclei in this tissue are stretch long and the tissue may appear wavy under a microscope. DENSE 2.1. 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. Where would you be able to find dense regular connective tissue in the body? Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. Fibroblasts are the primary cells present and they occur in rows parallel to the bundles of collagen fibers. 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 both connective tissue types, fibroblasts are the most abundant cells, which are located between the dense collagen bundles. 3. -It plays a significant role in the diffusion of gases, nutrients and metabolic wastes between the cells and the vessels that perfuse the tissue. Dense connective tissue Slide 15 Elastic connective tissue Slide 28 Mucus connective tissue Slide 87 . Click here to find out more about the three different types of connective tissue.. Matrix: Also known as the ground substance.
