Fluid Connective Tissue

Avascular Limits repair

Cartilage

Figure 4.10

Most common Tough and flexible Connects ribs to sternum Covers bone surfaces at joints

Hyaline Cartilage

Figure 4.10a

Resilient, flexible Outer ear Epiglottis

Elastic Cartilage

Figure 4.10b

Durable and tough Pads between vertebrae Between pubic bones At knee Resists compression Absorbs shock Prevents bone to bone damage

Fibrocartilage

Figure 4.10c

Tears in fibrocartilage pads can’t heal Joint mobility reduced Surgery—temporary or incomplete repair

Joint Injuries

AKA: Osseous Tissue Strong, resilient to shattering Osteocytes—bone cells Canaliculi—connect osteocytes to blood

vessels Periosteum—surrounds bone Can completely repair
