'the connective tissue is characterized by filling the intracellular spaces of the body and the interphase between the other important tissue, giving them support and assembly.
Morphologically, presents great amount of extracellular material (matrix) consisting of a portion nonstructural , called structural amorphous substance (SFA), and another fibrous
portion.
amorphous substance: primarily composed of water, proteins and polysaccharides. Can assume rigid consistency, for example, in bone tissue, and more liquid, such as blood plasma.
Fibers: a protein nature, are distributed as tissue, particularly:Collagen fibers → Frequently tissue conjunctive, formed by the protein collagen of high strength (whitish); Elastic fibers → fundamentally formed by the protein elastin, possessing considerable elasticity (yellowing); Reticular fibers → with reduced thickness, formed by the protein called reticulin, similar to collagen. So besides the function of filling the spaces between the organs and maintenance, all the diversity of tissue in an organism plays an important role in defense and nutrition. Major types in vertebrates can be divided into two groups, based on a classification considering the composition their cells and the relative volume between the elements of the extracellular matrix: tissue itself (the loose and dense), and the special tissue (adipose, the cartilage, the bone and blood).
Loose Connective Tissue is characterized by abundant intercellular substances presence and relative amount of fiber loosely distributed. In this tissue are present all the typical connective tissue cells: fibroblasts active in protein synthesis, macrophages with high phagocytic activity and plasma cells in antibody production.
Dense Tissue Called fibrous connective tissue, features lots of collagen fibers, forming beams with high tensile strength and low elasticity. It is typically found in two situations: forming tendons, mediating the connection between muscles and bones, and ligaments, joining bones together. organization of the collagen fibers in this class of fabric allows it to distinguish: not modeled when the fibers are distributed in a diffuse (scattered), and patterned, if ordinates.
Tissue Blood (Reticular) This fabric has the function of producing the typical cells of blood and lymph. There are two variations: hematopoietic tissue myeloid and lymphoid hematopoietic tissue. myeloid: It is found in bone marrow red present inside the cancellous bone of the medullary canal, responsible for the production of red blood cells (RBCs), certain types of white blood cells and platelets. lymphoid: You are in isolation in structures such as the lymph nodes, spleen, thymus and tonsils;'s role is to produce certain types of white blood cells (lymphocytes and monocytes)
Adipose Tissue The adipose tissue is rich in cells that store fat, with essential function of energy reserves. In birds and mammals (warm-blooded animals), aids in thermoregulation (insulator) being distributed beneath the skin which is the hypodermis.
Tissue Cartilaginous tissue cartilage devoid of blood vessels and nerves is formed by cells called chondrocytes and chondroblasts. The chondroblast synthesizes large quantities of protein fibers, and gradual reduction of their metabolic activity, is now called chondrocytes. Bone Tissue Far more resistant than the cartilaginous tissue, bone tissue is composed of a rigid matrix, composed mainly of collagen fibers and calcium salts and various cell types: osteoblasts, osteocytes and osteoclasts. Osteoblasts are bone cells young existing in regions where the bone tissue is in process of formation, resulting osteocytes which store calcium. Osteoclasts in turn, are giant cells that promote the destruction of bone matrix.
