Presentation Transcript

  1. Histology • Objective: To study different types of tissues and identify the followings: 1- Hyaline Cartilage (C.S) 2- Arteries and Veins (C.S) 3- Striated and Cardiac muscles (C.S) 4- Neurons and Spinal cord (C.S)

  2. Tissues and Histology • Histology: Microscopic Study of Tissues • Biopsy: removal of tissues for diagnostic purposes • Autopsy: examination of organs of a dead body to determine cause of death

  3. Major types of adult tissues: • 1- Epithelial • 2- Connective • 3- Muscle • 4- Nervous   

  4. Classification of epithelia • Number of cell layers • Simple • Stratified • Shape of apical surface cells • Squamous • Cuboidal • Columnar

  5. Classifications of Epithelia

  6. 2- Connective Tissues  

  9. C- Supporting connective tissues • Two types: • Cartilage • Bone  Cartilage and bone support the body

  10. Supporting connective tissues 1- Cartilage: • Cells called chondrocytes • Cells found in lacunae (capsules) • Perichondrium separates cartilage from surrounding tissues • Three types: hyaline, elastic and fibrocartilage

  11. Hyaline Cartilage  Figure 4.12g

  12. Elastic Cartilage Figure 4.12h

  13. Fibrocartilage

  14. 3- Muscle tissue • Specialized for contraction • Three types: • Skeletal:attached to bones • Cardiac: muscle of the heart • Smooth: muscle associated with tubular structures  

  15. Skeletal Muscle Tissue

  16. Cardiac Muscle Tissue

  17. 4- Neural tissue • Conducts electrical impulses. • Conveys information from one area to another.

  19. T.S. of Spinal Cord

  21. Nerve Cell
