Information about the connective tissue in the human body
Connective tissue is one of the four main types of tissues in the human body, which support and connect various types of tissues and organs. This tissue is growing from the medium lobe. The three types are epithelial tissue, muscle tissue, and nervous tissue. It is found among other tissues anywhere on the body, including the nervous system. In the central nervous system, the three outer membranes covering the brain and spinal cord (meninges) are made of connective tissue.
All connective tissues consist of three main components: fibers (elastic, collagen), the underlying material, and cells. Not all blood or lymph documents are considered connective tissue; Because it lacks fiber. All of them are immersed in the water of the body.
Connective tissue cells include: juvenile fibroblasts, fat cells, large macrophages, mast cells, and white blood cells
Connective tissue is divided into special connective tissue and special connective tissue. A specific connective tissue consists of soft connective tissue and thick connective tissue, and the thick connective tissue is divided into regular and irregular. The special connective tissue consists of retinal connective tissue, adipose tissue, cartilage, bone, and blood. Other types of connective tissue include: fibrous, elastic, and lymphoid. Granular tissue is the new vascular connective tissue that forms in the process of wound healing. Fibroblasts are the cells responsible for producing some connective tissue.
The first type of collagen, it is found in several forms of connective tissue, and constitutes 25% of the total protein content in the body of mammals.
The cells spread through the fluid outside the cells.
The base material, which is clear and viscous liquid, contains glycose aminoglycan and proteinoglycan to stabilize body water and collagen fibers in intercellular spaces. The staple substance slows the spread of nurses.
The fibers. Not all connective tissue is fibrous. Examples of non-fibrous connective tissue: adipose and blood tissue. Fatty tissue gives a mechanical support to the body and has other functions. Although there is no dense collagen network in adipose tissue, adipose tissue groups are kept together using collagen fibers and plates to keep them compressed in place, such as: the sole of the foot. The tissue (matrix) of blood is plasma.
Both the base material and proteins (fibers) form the connective tissue matrix. Collagen fibers connect the bones and other tissues together to the polypeptide chains alpha ligaments, tendons, skin, cornea, cartilage, bone, blood vessels, gut, and intervertebral discs.
Flexible fibers allow organs (such as the arteries and lungs) to bounce back estin and elastic fibers outside the cells
Reticular fibers form the scaffold of other cells, the third type of collagen the liver, bone marrow, and lymph organs.
Connective tissue has many functions, depending on the cell types and different classifications of fibers. The dense, irregular, loose connective tissue consists mainly of juvenile fibroblasts and collagen fibers, providing the appropriate medium for oxygen and nutrients to travel from capillaries to cells, carbon dioxide and waste from cells to circulation, and allowing members to resist tear and tensile forces. The dense connective tissue with regular structures forms the regular structures, and is the main functional component of the ligaments, tendons and broad muscle tendons, and is also found in specialized organs at a high level like the cornea. Elastic fibers consist of elastin and fibrillin, and help resist tensile forces. They are found in the walls of large blood vessels and some ligaments, especially the yellow ligaments.
In the hematopoietic and lymphoid tissues, the retinal fibers form the parenchyma (structural support) of the visceral tissue (functional part) of the organ.
The mesenchyme (intermediate fetal layer) is one of the types of connective tissue that is found in the developing organs in the fetus and has the ability to differentiate into all types of mature connective tissue. Mucous connective tissue is another type of relatively undifferentiated connective tissue found in the umbilical cord.
Different types of specialized tissue and cells are classified under the connective tissue spectrum, and they are as diverse as brown and white fatty tissue, blood, cartilage, and bone. Immune system cells, such as macrophages, mast cells and plasma cells, scatter in the soft connective tissue, providing the ground for initiating inflammatory and immune responses when antigens are detected.
Connective tissue disease and connective tissue tumor. One in ten people has connective tissue disorder. Connective tissue diseases include:
Connective tissue tumors: sarcomas, such as papillomas and peripheral neurodegenerative tumors in the nervous tissue.
Congenital diseases: Marfan syndrome and Danlos-Ahlers syndrome.
Degeneration of mucosal tumor: a pathological weakness of the connective tissue.
Mixed connective tissue disease: autoimmune disease, undifferentiated connective tissue disease.
Systemic lupus erythematosus: the main autoimmune disease in the connective tissue.
Scurvy: It occurs due to a lack of vitamin C, which is important for collagen production.
Characteristics of retinal and fatty connective tissue
Its cells are non-contiguous (there are spaces between cells).
Abundant interstitial material which is in three forms: liquid, semi-solid and solid.
The presence of fibers (white, yellow and retina).
It contains several types of cells (fibrous, corrosive, mast, fatty, plasma, and color-carrier).
It contains blood vessels and nerve cells.
Connective tissue is found in the blood, cartilage, and bone. It is usually considered connective tissue, but it differs from other connective tissues. The common phrase "special connective tissue" is used to combine these three tissues.
There are three types of connective tissue:
Special connective tissue.
Cartilage.
Bones
