• Nothing in the world can take the place of
  persistence. Talent will not nothing is more
  common than unsuccessful men with talent. Genius
  will not unrewarded genius is almost a proverb.

Cartilage

• Much harder than other types of connective tissue
  
• protein fibers mixed with ground substance -
  matrix
• chondrocytes - cartilage cells
• found in lacunae

9
1. Hyaline Cartilage

• Most abundant
• matrix contains chondroitin sulfate
• Contains collagen (not seen with microscope due
  to chondroitin sulfate)
• Found in trachea, ends of long bones, ribs,
• Acts as precursor to most bones

• Contains mainly elastin proteins
• Firm but flexible
• found in ears, nose, epiglottis

3. Fibrocartilage

• Mainly collagen protein
• Used as a shock absorber in joints
• Medial and lateral meniscus
• Found in Knee, intervertebral discs,

Bone

• Type of connective tissue
• Intercellular matrix very hard and durable
• Matrix produced by osteocytes
• Osteocytes found in lacunae
• Periosteum - membrane surrounding the bone -
  sustentacular

16
Bone

• Compact bone
• found in the middle areas of bones (not near
  joints)
• Marrow (yellow) filled with fat
• Spongy bone (cancellous)
• not as densely packed as compact
• filled with red marrow
• used to form blood cells

Blood

• Composed of
• Erythrocytes
• Leukocytes
• many different types
• nucleated cells
• Platelets
• Plasma proteins
• Fluid
• Helps maintain homeostasis for all cells in the
