Connective Tissue Flashcards
Functions
Binding of organs
Support for organs
Physical protection
Immune protection
Movement
Storage
Heat production
Transport
Ground substance
Mainly water
Hygroscopic proteoglycans
Proteins trap water to make a gel
Blast cells
Immature form
Mitotically active
Secrete ground substance and fibres
Fibroblasts
Connective tissue proper
Repair
Chondroblasts
Cartilage
Osteoblasts
Bone
Clast cells
Break down connective tissue
Work with blast cells
Osteoclast
Bone
Chondroclast
Cartilage
Cyte cells
Immobile
Mature form
Maintain/recycle/breaks down ground substance
Chondrocytes
Cartilage
Osteocytes
Bone
Connective tissue proper types
Loose areolar tissue
Dense connective tissue
Adipose connective tissue
Loose areolar connective tissue
Elastic fibres found in skin
Protects organs
Elastic fibres
Collagen fibres
Fibroblasts
Dense connective tissue
More collagen fibres then elastic
Densely packed
Fibroblasts
Adipose connective tissue
Storage of lipids
Protection
Energy production
Layer under skin
80-90% fat
Lipids and fatty acids
Rich blood vessel and nerve supply
Cartilage
Tough, flexible and rigid
80% ground substance
Lacks blood vessels and nerves
Relies on diffusion
Chondrocytes in lacuna
Hyaline cartilage
Most abundant
Smooth articular surface
Perichondrium
Chondrocytes in lacuna
Around synovial joints
Elastic cartilage
More flexible
Made of elastin - yellow and stretchy
Fibrillin - structural support of fibres
Chondroblasts
Lacuna
Fibrocartilage
Fibrous
Bundles of collagen fibres in all directions
Impact resistant
Shock absorber
Bone
Collagen fibres
Ground substance packed with hydroxyapatite
Lacunae
Osteocytes
Periosteum
Osteons
Haversian canals
Central canal - rich blood and verve supply
Blood
Erythrocytes
White blood cells
Matrix - plasma (gel)
Fibres made from fibrinogen which is soluble
