Connective Tissue
Cards in this deck (16)
- 1Connective tissue consists offew cells
ECM
-GAGs and proteoglycans
-fibres - elastin and fibrillin - flexibility
-collagen - 2CollagenType I - thick bundles
Type II - thin, interwoven, cartilage
Type III - delicate branching reticular fibres
Type IV - basement membrane, not distinctive - 3BloodECM
-ground substance = blood plasma
-fibres = fibrin clots (fibrinogen = liver)
Circulating cells
-erythrocytes, leucocytes, granulocytes (BEN), lymphocytes, monocytes, thrombocytes - 4Adipose tissueECM - Type I collagen
Cells - adipocytes, fibroblasts - 5White adiposeadult
widespread
uniocular
energy store, insulator, shock absorber - 6Brown adiposeneonates
restricted
mutliocular
-using production using mitochondria - 7CartilageECM - Type II collagen
chondroitin sulphate, proteoglycans
Cells
-chondroblasts surrounding mature cartilage in its perichondrium
-chondrocytes - found in spaces called lacunae - 8Elastichas elastic fibres but only visible with Verhoff stain
Ear and Epiglottis
dark staining
really densely packed - 9Hyalinecells are separated into little groups (isogenous groups)
nose
trachea
larynx
costal cartilages (ribs) - 10Fibrocartilagerows of chondrocytes in lacunae
Type I and Type II cartilage - 11BoneECM
-osteoid, Type I, calcium binding glycoproteins
Cells
-osteoblasts - form bone
-osteocytes in lacunae connected by canaliculi
-osteoclasts - macrophage-like, resorb bone - 12Woven boneformed first
weak
collagen randomly orientated - 13Lamellar bonemature bone
collagen organised
compact or cancellous
-cancellous receives blood from bone marrow
-compact organised into osteons that receive blood from vessels in Haversian canals - 14Areolar (loose) fibrocollagenousECM
-collagen type I, some elastic and reticular
Cells
fibroblasts, adipocytes,macrophages/mast calls, lymphocytes, plasma cells - 15Dense fibrocollagenousECM
-little ground substance - its dense
-loads of collagen fibres
Cells
-fibroblasts, defensive cells
Irregular = dermis
regular = ligaments and tendons - 16Reticular fibrocollagenousType III collagen
liver, lymph nodes
minimum ground substance
cells
-fibroblasts,
