Connective tissues are the major supporting tissue of the body. In connective tissue, cells that secrete the proteins of the fibers. Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body. Fibroblasts or fibrocytes are the primary cell in elastic connective tissue. This arrangement gives the tissue greater strength in all directions and less strength in one particular direction. Leukocytes, white blood cells, are responsible for defending against potentially harmful microorganisms or molecules. Ligaments and tendons are made of dense regular connective tissue. Connective Tissue Practice Quiz. It fills the spaces between muscle fibers, surrounds blood and lymph vessels, and supports organs in the abdominal cavity. Epithelium / Connective Tissue / Cartilage / Bone / Joint - Coggle Diagram: Epithelium / Connective Tissue / Cartilage / Bone / Joint ... Hyaline cartilage, elastic cartilage, & fibrocartilage . The external ear contains elastic cartilage. Blood has two components:  cells and fluid matrix (Figure 4.13). There are several important cell types and three main fibers: collagen, reticular and elastic. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. Description about Elastic Connective tissue for Medical students. Classification of connective tissue into three broad types is based upon the composition of its cellular and extracellular components and its function in the body. It derives its name from the Latin reticulus, which means “little net.”. Know THIS Slide for the Practical! Description: This section of elastic connective tissue is from the wall of the aorta. Organs, blood vessels, endoneurium of nerves . Achetez neuf ou d'occasion Choose from 500 different sets of elastic connective tissue flashcards on Quizlet. Basement membrane of epithelial. E.g. Areolar connective tissue: These are simplest and most widely distributed connective tissues. Connective tissue: characteristics, functions and types. Matrix Adipose connective tissue; Reticular tissue; 1. Bone is a highly vascularized tissue. collagen fibers. Elastic fibers (or yellow fibers) are an essential component of the extracellular matrix composed of bundles of proteins (elastin) which are produced by a number of different cell types including fibroblasts, endothelial, smooth muscle, and airway epithelial cells. Most abundant are the fibres composed of the protein collagen. The three main types of cartilage tissue are hyaline cartilage, fibrocartilage, and elastic cartilage (Figure 4.11). Secreted by fibroblasts, ground substance is made of water, polysaccharides, specifically hyaluronic acid, and proteins. As a consequence, it displays greater resistance to stretching. Identify the function for each type of connective fiber: Reticular holds adipose together and lymphatic tissues Elastic makes up ligaments and tendons allows for the tissues to stretch with the mucles and joints Collagen is used as a filler in tissue to provide cushion 5. reticular tissue location . Elastic and reticular fibers are better distinguished with special stains. Hematopoietic tissue is a fluid connective tissue, and so is the lymphatic tissue. reticular tissue function. All of these fiber types are embedded in ground substance. Lymph drains into blood vessels, delivering molecules to the blood that could not otherwise directly enter the bloodstream. Retrouvez A Chemical Study of Yellow Elastic Connective Tissue et des millions de livres en stock sur Amazon.fr. All connective tissues are characterized by the presence of a matrix in addition to cells. Figure 4.7. Objectives •Describe each type of connective tissue (CT) and explain where they are found. These fibers are able to stretch many times their length, and snap back to their original length when relaxed without loss of energy. It provides mechanical strength, physical and metabolic support to all or any the opposite kinds of tissues. Connective tissue is derived from the third germ layer, the mesoderm, which is the same source of origin of muscle tissue. Elastin is the protein that allows for tissue to regain its shape after being compressed or warped. Causes and specific symptoms vary by the di… provides supporting framework/soft internal skeleton. Elastic connective tissue is a technical term for body tissue that contains a large amount of elastin, one of the proteins that make up connective tissue in general. (glycoprotein, mucin, hyaluronic acid and chondroitin sulphate). Cartilage also provides flexible support for certain structures in adult humans including the nose, trachea, and ears. Majority are fibroblasts and macrophages. Fascial tissues differ in terms of their density and directional alignment of collagen fibers. Bone formation, Bone, and Developing Tooth. These combine to form a proteoglycan with a protein core and polysaccharide branches. Connective tissue contains various types of cells such as fibroblast, myofibroblast, adipose cells, mast cells, tissue macrophages, white blood cells, osteoblast, chondroblast and lympocytes. •List the types of cells, fibers, and other extracellular matrix components found in connective tissues. Osteocytes, bone cells, are located within lacunae. Areolar Tissue. Dense connective tissue. A plate of hyaline cartilage at the ends of bone allows continued growth until adulthood. It makes up a template of the embryonic skeleton before bone formation. Reticular cells produce the reticular fibers that form the network onto which other cells attach. The extracellular matrix found in elastic tissue is made out of only a limited amount of ground substance. At the end of this class you should be able to… • Describe characteristics & components of CT • Classify CT • Correlate CT type with their function 3. Cartilage is a form of fibrous connective tissue that is composed of closely packed collagenous fibers in a rubbery gelatinous substance called chondrin. Loose Connective Tissue (LOCT) Loose connective tissue - delicate, flexible, not very resistant to stress, well vascularized. A large number of capillaries allow rapid storage and mobilization of lipid molecules. Compact bone is solid and has greater structural strength. Can you name the 10 tissue types shown in the histology slides? Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. The histology of transverse tissue from long bone shows a typical arrangement of osteocytes in concentric circles around a central canal (Figure 4.12). Wählen Sie aus erstklassigen Inhalten zum Thema Elastic Connective Tissue in höchster Qualität. Which letter is labeling the connective tissue and what is the connective tissue here histologically? Some white blood cells have the ability to cross the endothelial layer that lines blood vessels and enter adjacent tissues. Connective tissue (Textus connectivus): Clicking the underlined terms opens pages with image overviews / explanations. There are many different types of connective tissue, with loose and dense connective tissue … Collagen, the other main protein that makes up connective tissue, provides rigidity and structure. white blood cells. Connective (supporting) tissue may be a voluminous, strong, yet elastic sort of tissue with significant physical body roles. Loose irregular connective tissue contains numerous cells and a loose fiber arrangement in a moderately viscous fluid matrix. Function: Will resist compression forces . Bone’s rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate.
