Autoimmune Diseases Connective tissue disease refers to a group of disorders involving the protein-rich tissue that supports organs and other parts of the body. Examples of connective tissue are fat, bone, and cartilage. These disorders often involve the joints, muscles, and skinbut they can also involve other organs and organ systems, including the eyesheartlungskidneysgastrointestinal tract, and blood vessels.
Connective tissue is made up of a small fraction of cells and a majority of extracellular substance which keeps the cells separated.
The two types of cells found in connective tissue include fibrocytes or fibroblasts and fat cells, which are fixed cells. Additionally, the extracellular substance separating the cells is made up of three types of fibers, including collagen fibers, reticular fibers and elastic fibers.
Cartilage Cartilage is a type of supporting connective tissue. Cartilage is a dense connective tissue, consisting of the chondrocyte cells. Cartilage connective tissue includes hyaline cartilage, fibrocartilage and elastic cartilage. The fibers in the cartilage connective tissue include collagen and elastic fibers.
Cartilage connective tissue has limited ground substance and can range from semisolid to a flexible matrix. Bone Bone is another type of supporting connective tissue. Bone, also referred to as osseous tissue, can either be compact dense or spongy cancellousand contains the osteoblasts or osteocytes cells.
Bone connective tissue is made up of collagen fibers and has rigid, calcified ground substance. Sciencing Video Vault Adipose Adipose is another type of supporting connective tissue that provides cushions and stores excess energy and fat. It contains reticular cells and is made up of reticular fibers.
The extracellular substance of adipose connective tissue is made up of a tight pack of cells with a small amount of gelatinous ground substance.
Blood Blood, also referred to as vascular tissue, is a type of fluid connective tissue. Blood connective tissue contains three types of cells including erythrocytes, leukocytes, and thrombocytes. The fibers found in blood connective tissue are soluble proteins that form during clotting and the extracellular substance making up blood connective tissue is the liquid blood plasma.
Lymphatic connective tissues are responsible for the manufacture of all the blood cells and immunological capability. It contains leukocytes cells and is made of fibers which are soluble liquid proteins that form during clotting. The extracellular substance of hemapoetic tissue is blood plasma.
Elastic Elastic connective tissue helps maintain blood pressure and promotes normal exhalation. Elastic connective tissues consist of chondrocytes cells and are made up of elastic fibers. The extracellular substance of elastic connective tissue is composed of limited ground substance and is structured in a flexible, but firm matrix.
Fibrous The fibrous connective tissue functions to provide strength to the inner layer of skin and strength, allowing it to handle forces of joint movements. Fibrous connective tissue contains fibroblast cells and is made up of fibrous fibers.
It is a dense connective tissue, with its extracellular substance consisting of parallel or irregularly arranged bundles of fibers with few cells and little ground substance.Video: Bone Tissue: Functions and Types In this lesson, we will explore bone as a connective tissue. We will discuss the anatomy of bone, as well as the cell types which make up bone, including.
Bone Tissues: Connective tissue. Lines their external surfaces and internal cavities.
Bone Tissues: Nervous tissue. Found in nerves. Bones are quite innervated. Outer layer is dense connective tissue which unsheathes the bone. Inner layer is primarily bone-building osteoblasts. Sharpey's fibers. Attach periosteum to underlying compact bone.
CONNECTIVE TISSUE. Connective tissue consists of cells separated by varying amounts of extracellular substance.
In connective tissues cells typically account for only a small fraction of the tissue . Hyaluronic acid is a natural substance produced by the human body. It is present in every tissue of the body, with the highest concentrations occurring in connective tissues such as skin and cartilage.
Mixed connective tissue disease damages the muscle fibers, so the muscles may feel weak and sore, especially in the shoulders and hips. Tasks such as lifting the arms above the shoulders, climbing stairs, and getting out of a chair can become very difficult.
Connective tissue is an essential part of a body. It helps hold our body together, supports other tissues and even transports substances. Learn more about its importance and take a quiz at the end.
