Presentation Transcript


  1. Animal Structure and Function

  2. Tissue Groups of cells with a common structure and function

  3. Tissues • Epithelial Tissue • tightly packed cells used for lining • Connective Tissue • cells scattered through an extracellular matrix • Nervous Tissue • transmits signals (neurons) • Muscle Tissue • fibers for contraction

  4. Epithelial Tissue • Cell layers • Simple • Stratified • Pseudostratified • Shape of Cells • Cuboidal • Columnar • Squamous

  5. Connective Tissue • Collagenous Fibers • Collagen (most abundant protein) • Elastic Fibers • Elastin (protein) • Reticular Fibers • Collagen • join connective tissues

  6. Connective Tissue • Loose Connective Tissue • binds epithelial to underlying tissue • Fibroblasts (extracellular fibers) • Macrophages (immune system)

  7. Connective Tissue • Adipose Tissue • stores fat • Fibrous Connective Tissue • Tendons • Ligaments

  8. Connective Tissue • Cartilage • chondrocytes • Bone • osteoblasts • Haversian system

  9. Connective Tissue • Blood • plasma • erythrocytes • leukocytes • platelets

  10. Nervous Tissue • Neurons • Cell body • Axons • Dendrites

  11. Muscle Tissue • Skeletal • Cardiac • Smooth
