HLSC 2F95 Lecture Notes - Extracellular Fluid, Red Blood Cell, Parathyroid Gland
Document Summary
Cartilage and bone (forms of connective tissue = multifunctional and associated with muscular skeletal system (movement) Articulations: where 2 or more bones meet. Connection tissue connects body to sources (food, animals,etc) Matrix = what cells are imbedded in. Tissue fluid (contained in ground substance= mostly water) Fixed macrophages (responsible for phagocytosis: gobble up pathogens/garbage) Mesenchynal cells (source for other cells: differentiate) Melanocytes (produce melcomman: pigment to protect us from ultra violet rays) Neutrophils and esnophils (phagocytic cells and infection/tissue/injury protection) Growth (longitudinal in bone at epithyseal plates) Hayaline (skinny) : fetal skeleton- epiphysical plate at articular surfaces for support (most. Intervertrbral cushioning (support weight of vertebrae) (types:) common) Fibrous: intervertrbral discs symphysis pubis stemoclavicular joint tmj (tempermenticular joint) Pericardium: (outside of cartilage) divide, produce matrix: appositional growth (add cartilage to others) Diffusion through matrix cartilage gets blood at perimeter perichordrium. Limited repair capability (can sew on it to place it got ripped but never will be the same strength)
