structure, this tissue connects body parts, Found everywhere in the body and is the most abundant type, There are variations in blood supply, Most connective tissue is well vascularized, Exceptions are tendon and ligament…cartilage is avascular, Connective tissue is made up of a number of different types of cells. It also is made up of varying amount of nonliving substance found outside of cells, this is called the extra cellular matrix. The fibers can include collagen (white), elastic (yellow), and reticular (fine), Function, Primary function is protection, supporting, and binding together, types of tissue, bone- Composed of osteocytes sitting in pits called lacunae, The lacunae are surrounded by layers of a very hard matrix that contains calcium salts and a large number of collagen fibers, Has the ability to protect and support other organs, cartilage-There are 3 main types of cartilage: Hyaline, Fibrocartilage,Elastic Cartilage, Hyaline is the most abundant in the body and is found in joints, attaches ribs to sternum, growth plates, and in the larynx, Fibrocartilage is more rigid and it found between the vertebrae in the spinal column, Elastic Cartilage is found in the ear as well as tip of the nose, Tendons/ligaments- Collagen fibers are the main matrix element, This tissue forms strong, ropelike structures, Tendons – resistant to stretch, more collagen, Connect muscle to bone, Ligaments – will stretch more than tendons, contain more elastin, Connect bone to bone, parts of the body, bone and cartilage, tendons and ligaments, blood and lymph, fat, types of tissues 2, Areola – most widely distributed connective tissue, Resembles cobwebs, think of it as tissue or organ glue, Cushions and protects body organs, Because of the loose, fluid nature…it also serves as a reservoir for water and salts for surrounding tissues, When a body part is injured, the areolar tissue will soak up the excess fluid and become swollen…this is better known as edema, Adipose, or commonly known as fat, will form a subcutaneous layer, Acts to insulate the body against temperature differences and mechanical trauma, Can also surround specific organs for protection- kidneys, Stored in deposits around the body to be used for energy if needed- hips and breasts, types of tissues 3, Reticular connective tissue, Consists of a delicate network of reticular fibers associated with reticular cells, which resemble fibroblasts, Will form a stroma, which is an internal framework of an organ, Found in certain sites of the body that can support many free blood cells- lymph nodes, spleen, bone marrow, Blood or vascular tissue, Serves as the transport vessel for the cardiovascular system, as well as transporting nutrients, wastes, and respiratory gasses throughout the body, Is considered a connective tissue because it is made up of cells surrounded by a fluid matrix (blood plasma), Fibers are only evident during clotting
