Dense connective tissue - want to learn more about it.
Adipocytes are cells that store lipids as droplets that fill most of the cytoplasm. Mast cells Mast cells are relatively large, rounded cells that contain numerous granules which often obscure the nucleus. This arrangement gives the tissue greater strength in all directions and less strength in one particular direction.
For example, collagen in skin, bone, tendons, and ligaments resists pulling forces, whereas collagen found in joint cartilage and between vertebrae resists compression.
Plasma cells Plasma cells produce antibodies, which are a kind of protein that combines with foreign substances called antigens in a highly specific manner. All connective tissues, including the loose variety, are composed of two basic components: The number and type of adipocytes depends on the tissue and location, and vary among individuals in the population.
Identify the space indicated by the yellow arrow. It makes up a template of the embryonic skeleton before bone formation. Tissue fluid When blood passes through a capillary, the hydrostatic pressure at the arterial end is greater than at the venous end. Adipose tissue also provides thermal insulation, and it contributes to body contours such as the female breasts and hips.
It is also located in the larynx. All of these fiber types are embedded in ground substance. In the light microscope, plasma cells exhibit a very distinctive appearance. The main property of elastin is that after being stretched or compressed, it will return to its original shape. What is function of the structures indicated by the red arrow.
In addition to its function of ingesting bacteria and other exogenous matter, macrophages play an important role in the immune response by presenting processed antigen to lymphocytes. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Young athletes, dancers, and computer operators; anyone who performs the same movements constantly is at risk for tendinitis.
In the absence of microfibrils, however, the elastin becomes deposited as sheets of elastin. In sheet arrangement collagen bundles and matrix are distributed in irregular patterns, sometimes in the form of a network. Cartilage The distinctive appearance of cartilage is due to polysaccharides called chondroitin sulfates, which bind with ground substance proteins to form proteoglycans.
The condition causes pain and tenderness in the area around a joint. Fibrocartilage is tough because it has thick bundles of collagen fibers dispersed through its matrix. Macrophages are derived from monocytes, which enter loose connective tissue from the blood and transform into macrophages.
What are 3 locations for this tissue. It is customary to describe dense conective tissue as "irregular" or "regular". Erythrocytes, red blood cells, transport oxygen and some carbon dioxide. Dense Connective Tissue Connective tissue is generally classified according to the density of its constituent fibers loose or dense and the orientation of those fibers irregular or regular.
In dense connective tissue, fiber occupies more space than the cells and ground substance, and appears closely packed in tissue sections. It allows water, salts, and various nutrients to diffuse through to adjacent or imbedded cells and tissues.
Reticular cells produce the reticular fibers that form the network onto which other cells attach. Identify the structure indicated by the dashed green circle. Identify the membrane indicated by the yellow arrow. Particularly strong forms make up the tough capsules around certain organs, such as the kidneys, the liver, and some glands.
Like blood cells, mast cells are derived from hematopoietic stem cells and are part of the immune system. Dense Connective Tissue a Dense regular connective tissue consists of collagenous fibers packed into parallel bundles. This tissue gives rigid support as well as elasticity. These long-lived cells lose the capacity to divide when they become filled with lipid.
A Fluid Connective Tissue Blood is a fluid connective tissue containing erythrocytes and various types of leukocytes that circulate in a liquid extracellular matrix. The fluid that collects in these vessels is referred to as lymph.
Dense connective tissue, on the other hand, has many more fibers densely arranged. In contrast, white fat adipocytes store lipids as a single large drop and are metabolically less active. dense regular connective tissue Tendon, which is a strap like body that connects bone to muscle, is made of dense regular connective tissue.
You can find an example in slide 9. Dense regular connective tissue consists of orderd and densely packed fibres and cells. The fibres are loose and very elastic in nature.
They are secreted by the surrounding connective tissue cells. It is composed of a dense fibrous connective tissue (type I collagen), and it is only innervated on its periphery. Behind the disc, however, there is a well-vascularized and innervated tissue called retrodiscal tissue, which when loaded can elicit pain.
The two types of dense connective tissue are the dense regular and dense irregular connective tissues. \n This tissue contains closely packed, parallel, often wavy bundles of collagen fibres, with scanty ground substance (figure 6).
Fibrous connective tissue also holds body parts together, but its structure is a bit more rigid than loose connective tissue. Fibrous connective tissue is found in ligaments, tendons, cartilage, and bone. Dense regular connective tissue provides connection between different tissues in the human body.
The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. 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 sheet arrangement.Dense fibrous connective tissue
