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.” Calvin Coolidge Connective Tissue ‘Doc’ Mullins CRT LRTC RCP Capital High School Honors Human Anatomy & Physiology I

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: 7

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: 8

2. Elastic Cartilage : 

2. Elastic Cartilage Contains mainly elastin proteins Firm but flexible found in: ears, nose, epiglottis 9/21/2009 Page: 10

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: 12

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: 14

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: 15

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: 17
