Class Topics :Class Topics “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. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent.”

Cartilage :Cartilage Much harder than other types of connective tissue
protein fibers mixed with ground substance - matrix
chondrocytes - cartilage cells
found in lacunae 9/21/2009 Page: 2
1. Hyaline Cartilage :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 9/21/2009 Page: 3

2. Elastic Cartilage :2. Elastic Cartilage Contains mainly elastin proteins
Firm but flexible
found in: ears, nose, epiglottis 9/21/2009 Page: 5
Slide 6:9/21/2009 Page: 6
3. Fibrocartilage :3. Fibrocartilage Mainly collagen protein
Used as a shock absorber in joints
Medial and lateral meniscus
Found in: Knee, intervertebral discs, 9/21/2009 Page: 7
Slide 8:9/21/2009 Page: 8
Bone :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 9/21/2009 Page: 9
Bone :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 9/21/2009 Page: 10

Blood :Blood Composed of:
Erythrocytes
Leukocytes
many different types
nucleated cells
Platelets
Plasma proteins
Fluid
Helps maintain homeostasis for all cells in the body 9/21/2009 Page: 12
