Rheumatoid Arthritis (RA): Rheumatoid arthritis is one of the most common connective tissue diseases and can be inherited. RA is an autoimmune disease, meaning the immune system attacks its own body. In this systemic disorder, immune cells attack and inflame the membrane around joints.
Explanation: Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage. ... Any tissues can essentially be broken down into epithelium (or endothelium), muscle tissue, neural tissue, or connective tissue.
The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants—bone, ligaments, tendons, cartilage, and adipose (fat) tissue.
All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground substance and cells. Not all authorities include blood or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.
Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. ... Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide.
Skin is made up of connective tissue that consists of cellular components and an extracellular matrix. The extracellular matrix contains two main types of macromolecules: polysaccharide glycosaminoglycans and collagens.
Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. Connective tissues can have various levels of vascularity. Cartilage is avascular, while dense connective tissue is poorly vascularized.
Early signs and symptoms often involve the hands. Fingers might get puffy, and the fingertips become white and numb, often in response to cold exposure. In later stages, some organs — such as the lungs, heart and kidneys — can be affected. There's no cure for mixed connective tissue disease.
Fibromyalgia is one of a group of chronic pain disorders that affect connective tissues, including the muscles, ligaments (the tough bands of tissue that bind together the ends of bones), and tendons (which attach muscles to bones).
Collagen is found in the tendons, ligaments, skin, cartilage, bone and blood vessels. Elastin is found in the ligaments and skin. When these connective tissues become inflamed, this can harm the proteins and surrounding areas of the body. This is known as a connective tissue disorder.
