- In connective tissues cells typically account for only a small fraction of the tissue volume. The extracellular substance consists of fibres which are embedded in ground substance containing tissue fluid. Fibres in connective tissue can be divided into three types: collagen fibres, reticular fibres and elastic fibres.

- A bunch of collagen fibers forms a primary fiber bundle, and a group of primary fiber bundles forms a secondary fiber bundle. A group of secondary fiber bundles, in turn, forms a tertiary bundle, and the tertiary bundles make up the tendon.

Muscle The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber. The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.keletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis. Muscle fibres are cylindrical, and multinucleated.

Extracellular matrix COLLAGEN 1 a 1 and COLLAGEN 1 a 2. The major collagen of skin, tendons, and bone is composed of two chains of collagen 1 a 1 and one chain of collagen 1 a 2. Different tissues can modify this collagen after it is produced (by varying the degree of cross-linking between chains).ollagen is the most abundant protein in the human body. There are at least 19 kinds of vertebrate collagen coded by at least 33 genes. In humans, collagens are synthesized by a number of cells including fibroblasts and a number of epithelial cells.

Reticular Connective Tissue Reticular connective tissue is a type of connective tissue. It has a network of reticular fibers, made of type III collagen. Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures. (from wikipedia)

Reticulocyte Reticulocytes are immature red blood cells, typically composing about 1% of the red blood cells in the human body. In the process of erythropoiesis (red blood cell formation), reticulocytes develop and mature in the bone marrow and then circulate for about a day in the blood stream before developing into mature red blood cells. Like mature red blood cells, in mammals reticulocytes do not have a cell nucleus.

- Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries.These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.he elastic fiber is formed from the elastic microfibril (consisting of numerous proteins such as microfibrillar-associated glycoproteins, fibrillin, fibullin, and the elastin receptor) and amorphous elastin.

The Tendinosis/Tendinopathy Injury Tendons and ligaments also contain proteoglycans, elastin, and fibroblast cells. The collagen, elastin, and proteoglycans form the extracellular matrix. The fibroblast cells are embedded in the matrix and in fact synthesize and secrete the matrix collagen, elastin, and proteoglycans.

Collagen Collagen, in the form of elongated fibrils, is mostly found in fibrous tissues such as tendons, ligaments and skin. It is also abundant in corneas, cartilage, bones, blood vessels, the gut, intervertebral discs and the dentin in teeth.In muscle tissue, it serves as a major component of the endomysium.ollagen is not only a structural protein. Due to its key role in the determination of cell phenotype, cell adhesion, tissue regulation and infrastructure, many sections of its non-proline-rich regions have cell or matrix association / regulation roles.

Connective Tissue Study Guide EXTRACELLULAR MATRIX. The extracellular matrix of connective tissue is composed of ground substance and fibers. In ordinary connective tissue, the ground substanc e consists mainly of water. The principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element.The extracellular materials which comprise the matrix are produced by fibroblasts.he extracellular fibers of connective tissue are traditionally classified into three types: 1  Collagen fibers confer main tensile strength, and are the stuff of scars. 2  Elastic fibers confer elasticity. 3  Reticular fibers (really, a special form of collagen) provide a delicate supporting framework for loose cells.

12V solar panel The time it takes for your solar panel to charge your battery depends on the current of the panel you choose. As battery capacity is measured in A/h (amp-hours), you need to know the solar panel current to estimate how quickly it will charge your battery.For example, A 100W motorhome solar panel normally produces 4-5A per hour in bright sunshine.If you have a 100A/h battery, this will take approximately 100/5 = 20-25 hours of sunshine to charge from 0% to 100%. The current of 12 volt solar panels or charging kits is typically proportionate to their wattage.s battery capacity is measured in A/h (amp-hours), you need to know the solar panel current to estimate how quickly it will charge your battery. For example, A 100W motorhome solar panel normally produces 4-5A per hour in bright sunshine.

- Collagen is created by fibroblasts, which are specialized skin cells located in the dermis. Fibroblasts also produce other skin structural proteins such as elastin (a protein which gives the skin its ability to snap back) and glucosaminoglycans (GAGs).

Structure and Function of Skeletal Muscle Near the end the collagen merges to form the tendons, which attach the muscle to the bone. It is through this connective tissue that the force generated by the individual cells is transmitted to the bone. A group of muscle cells are bundled together by collagen to form a fascicle.Since muscle cells are elongated and cylindrical, each muscle cell is usually called a muscle fiber.In skeletal muscle, the muscle fibers are very large, multinucleated, and up to several millimeters in length. group of muscle cells are bundled together by collagen to form a fascicle. Since muscle cells are elongated and cylindrical, each muscle cell is usually called a muscle fiber.

Histology Testbank: Connective Tissue 1a There are three types of fibers found in connective tissue: collagen fibers, elastic fibers, and reticular fibers. Collagen fibers are the most abundant fiber type in connective tissue. Purkinje fibers are seen in the heart. Purkinje fibers are specialized muscle fibers. 3. Which connective tissue cell type contains properties of smooth muscle cells? a. Fibroblast b. Myofibroblast c. Histiocyte d. Plasma cell e. Mast cell. Answer: b. Myofibroblasts contain properties of both fibroblasts and smooth muscle cells. Fibroblasts, histiocytes, plasma cells, and mast cells are routinely seen in loose connective tissue. Fibroblasts produce collagen. The fibroblast also produces the ground substance in connective tissue.

Histology@ Yale Cells of the Connective Tissue Proper. Although the connective tissue has a lower density of cells than the other tissues you will study this year, the cells of these tissues are extremely important. Fibroblasts are by far the most common native cell type of connective tissue. The fibroblast synthesizes the collagen and ground substance of the extracellular matrix. These cells make a large amount of protein that they secrete to build the connective tissue layer. Some fibroblasts have a contractile function; these are called myofibroblasts. Chondrocytes and osteocytes form the extracellular matrix of cartilage and bone.

Collagen fibers, reticular fibers and elastic fibers. A comprehensive understanding from a morphological viewpoint. Individual collagen fibrils (i.e., unit fibrils) in collagen fibers have a characteristic D-banding pattern whose length is ranges from 64 to 67 nm, depending on tissues and organs.During fibrogenesis, collagen fibrils are considered to be produced by fusing short and thin fibrils with tapered ends.lectronmicroscopically, reticular fibers are observed as individual collagen fibrils or a small bundle of the fibrils, although the diameter of the fibrils is thin (about 30 nm) and uniform.
