Histology of Cardiovascular system, อ้างอิง: Histology Cardiovascular…

- - - - Thick : ventricle
      - Cardiac muscles : many direction
      - Elastic fiber
      - Atrium : Pectinate muscle
      - Intercalated disc: ยึดด้วย gap junction และ desmosome
    - - Viseral pericadium
      - Mesothelium : serous fluid
      - Fibroelastic connective tissue : elastic fibers
      - Subepicardial layer
        : loose connective tissue = fat cells
        : coronary artery , cardiac vein
        : SA node
    - - Thin : ventricle
      - Endothelium
      - Subendothelium
        
        dense connective tissue
      - Subendocardium
        
        Purkinje fibers: มีGlycogeen ในcytoplasm
      - Thick : artrium
      - สัมผัสเลือด
  - - - 2 valve
        
        Tricuspid valve
        
        Bicuspid valve
      - Endocardium : thick atrium > ventricle
        AV > semilunar valve
      - Central plate : dense fibrous connective tissue
    - - 2 valve
        
        Pulmonary valve
        
        Aortic valve
      - Endocardium : thick atrium > ventricle
        AV > semilunar valve
      - Central plate : dense fibrous connective tissue
    - - ที่เกาะของ valve
