Connective tissues

  1. 1. Connective Tissues (pg 6)
  2. 2. Page 6 • Leave space for drawings
  3. 3. Connective Tissues • Functions: Bind structures together, support, transport, protection
  4. 4. Connective Tissues • Functions: Bind structures together, support, transport, protection • Contains few cells and an abundant intercellular matrix (Matrix = space between cells) • The matrix is filled with fibers that are produced by the cells, including collagen fibers and elastic fibers
  5. 5. Types of connective tissue 1. Loose (areolar): packing material. Attaches skin to underlying tissues. Fills the spaces between muscles.
  6. 6. Types of connective tissue 1. Loose (areolar): packing material. Attaches skin to underlying tissues. Fills the spaces between muscles. 2. Adipose tissue: Fat. Provides energy storage, cushioning around organs, and insulation
  7. 7. Types of connective tissue 1. Loose (areolar): packing material 2. Adipose tissue: Fat. Provides energy storage, cushioning around organs, and insulation 3. Dense fibrous: Forms tendons (connect muscle to bone) and ligaments (connect bones to each other)
  8. 8. Types of connective tissue 1. Loose (areolar): packing material 2. Adipose tissue: energy storage and cushioning 3. Dense fibrous: Forms tendons (connect muscle to bone) and ligaments (connect bones to each other) 4. Elastic: Can stretch and then return to normal length. Vocal cords, ligaments between vertebrae
  9. 9. Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible
  10. 10. Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton
  11. 11. Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton b. Fibrocartilage: strong shock absorber. Found in pads between vertebrae and in the knee
  12. 12. Types of connective tissue 5. Cartilage: Contains protein chondrin, which is stiff but flexible a. Hyaline cartilage: Found at end of long bones, where ribs attach to sternum, rings of trachea, fetal skeleton b. Fibrocartilage: strong shock absorber. Found in pads between vertebrae and in the knee c. Elastic cartilage: more flexible. Found in external ear, epiglottis
  13. 13. Types of connective tissue 6. Bone: Most rigid connective tissue. Fibers are surrounded by calcium salts. Provides framework for body.
  14. 14. Types of connective tissue 6. Bone: Most rigid connective tissue. Fibers are surrounded by calcium salts. Provides framework for body. 7. Blood: Red and white blood cells are suspended in a liquid matrix (plasma). Transports oxygen and nutrients
  15. 15. Output (pg 7) Make a cartoon character out of one type of connective tissue Must include: • A color picture • A name • Description of the character’s job • List of the character’s hobbies
