Classification of CT - Coggle Diagram

- - - - flows w/i cardiov system
      - consists of blood plasma(liquid ECM) and formed elements (red, white cells and platelets)
    - - flows w/i lymphatic system
  - - - elastic
        
        Abundant elastic fibers + collagen, making matrix more elastic than hyaline. Supports structures deformation (larynx, epiglottis, external ear); proteoglycans
      - fibrous
        
        Structural support for musculoskeletal system. Found in intervertebral discs of spine and insertions of ligaments and tendons.
      - hyaline cartilage
        
        abundant, relatively weak
        
        e.g: anterior ends of ribs, respiratory cartilage - nose, trachae, bronchi; nasal septum, ends of long bones
        
        flexibility and movement
    - - compact
        
        contains osteons, stores calcium&phosphorous, protection/support
      - spongy (BM)
        
        Cancellous bone- porous inner bone tissue lies underneath compact bone; lacks osteons, stores triglycerides (yellow marrow) n produces blood cells (red marrow)
      - Cortical bone- outer layer of bone and forms shaft of long bones
        
        composed of rod-shaped units - Osteons/ Haversian systems
  - - - Adipose
        
        adipocytes dominant
        
        white adipose(energy storage); brown(heat production)
        
        insulation, energy source, temp control
      - Reticular
        
        predominates in locations where high cellular content. Branched and mesh-like pattern (reticulum), fibers are actually type III collagen fibrils.
      - Areolar tissue
        
        most common of CT
        
        widely distributed; strength, elasticity, support
    - - dense regular
        
        tendons pulling along fibre axis; collagen fibres not a living tissue
        
        slow healing, attachment
        
        tendons (muscle to bone); Ligaments (bone to bone); aponeuroses(muscle to muscle)
      - irregular
        
        arranged in parallel bundles, mostly consist of collagen fibers, less GS than loose CT; pericardium
      - elastic
        
        fibroblasts. present in non-load bearing parts such as nose, ears, epiglottis. Lungs, arteries, dermis layer, ligaments, tendons.
