Connective Tissue
Question | Answer |
---|---|
3 componets of all connective tissue | Amorphois Ground substance, Tissue fluid and fibers |
Ehlers Danos Syndrome | heritable, affects collagen structure and function |
Marfan syndrome | hereditary defect of elastin and fibrillin |
What is a GAG? name the four groups | Glycosaminoglycans are long unbranched polysaccaride chains with repeating disacaride units. Hyluronic acid, chonroitin sulfate, heparin sulfate, and keatin sulfate |
What is a proteoglycan | contain more sugar than protien |
What is a glycoprotein | lots of protien with little sugar, organizes elastin into fibers, and if absent causes elastin to form sheets |
Fibronectin | involved in wound healing and clotting, plasma form is disolved in blood. Mediates cell adhesion and uses integrins. also binds collagen and heparin |
Laminin | component of basement membranes, uses integrins, and binds to type IV collagen and entactin |
chondronectin | attaches chondrocytes to type II collagen. Functions in development and maintainence of cartilage |
Osteonectin | Found in bone, links minerals to type 1 collagen |
Type 1 cartilage | Bone, Dense and loose connective tissue, tendons and fasia |
Type II cartilage | Hyaline and elastic caritlage |
Type III cartilage | Liver lymph nodes, connective tissue, vessels |
Type IV and VII | Basement membranes, signal where one tissue ends and another begins |
Where is loose connective tissue found | Adentitia o blood vessels, propria of GI |
Adipose tissue location | subcuanteous layer, covers some organs |
Elastic fiber location | Elastic cartilage, major arteries, some lung, some dermis, and elastic ligaments |
Dense Irregular | no partiular orientation, most abundant |
dense regular location | tendons and ligaments |
two types of elastic fibers | elastin and fibrillin |
location of reticular fibers and associated collagen type | liver, bone marrow, endorcrine glands, TYPE III |
What is heterotropic ostification | formation of bone within soft tissue |
benign tumor suffix | "oma" |
malignant tumor suffix | "sarcoma" |
