Term | Definition |
Connective Tissue Classes | Connective tissue, cartilage, bone and blood |
Extracellular Matrix (ECM) | cells are suspended/ embedded in this. Sugar mesh |
Structural Elements Connective Tissues | Ground substance, fibers and Cells |
Ground Substance | Gel like material that fills space between cells. supports weight. |
Connective Tissue Fibers | In between bones and organs. |
Collegen | most abundant connective tissue. Tough |
Elastic Fibers | Bugy cords, stretch and recoil |
Reticular | Short ones. fine highly branched fibers |
Blast cells | Cell providing. |
Fibroblast | found in connective tissue proper. Fibers and collegen |
Chondroblast | found in cartilage |
Osteoblast | found in bone. |
Hematopietic | In bone marrow. early cells that come out before blood cells. |
Cyte | Means cells. Mature cells |
Fat cells | Hollow energy source. |
White blood cells | Tissue response to injury |
Mast cells | Release histamine |
Macrophages | Eat, big eater. |
Connective tissue Proper | except bone, cartilage and blood. |
CT proper Loose | Areolar, Adipose and Reticular |
CT proper Dense | Dense regular, Irregular and elastic |
Areolar Connective Tissues | Most widely distributed ct |
Adipose Tissue | White Fat, Brown Fat |
Reticular Connective Tissue | Fibers are thinner reticular fibers, Lymph nodes, spleen, and bone marrow |
Dense regular connective tissue | Poorly vascularized, Tendons and ligaments. |
Dense irrgular connective tissues | Dermis. Fibrous joint capsules. |
Elastic connective tissue | Walls of many large arteries. Has to give aroitia |
Cartliage | 80% water with packed collagen fibers. |
Chondrocytes | Cells of cartliage |
Avascular | receives nutrients from membrane surrounding it, Prolonged healing time |
Hyaline Cartilage | Most abundant. Found in tips of long bones, nose and on the ribs. |
Elastic Cartilage | More Elastic, Ears and Eplglottis |
Fibrocartilage | Strong found in Intervertbral Discs. Bones of spine. Front of pelvis |
Bone | also called osseous tissue |
Osteons | Individual structural units |
Blood | type of connective tissue. fluid |
Muscle tissue | Skeletal, Cardiac and Smooth |
Skeletal Muscle Tissue | Control of brain. Voluntary Muscle |
Muscle Fibers | Multi nucleated, Muscle activity |
Cardiac Muscle Tissue | walls of heart. one nucleus per cell. contracts on own. |
Smooth Muscle Tissue | walls of hollow organs. no Visible strations. Anything you can control, Flushed |
Nurons | conduct nerve impulses, Transport |
Gilia | Supportive cells |
Cutaneous membrane | Skin, Epidermis and Dermis |
Mucous Membranes | Mouth, anus and vagina |
Serous Membranes | Line body cavity thin secretion. |
inflammation | release of chemicals, dilation of blood vessels, Clotting of blood. |
Organization | restores blood supply, blood clot is replaced with granulation tissue. |
Regeneration | the scab detaches, skin thickens, some scar tissue. |
