What is the dense (compact) bone? 1. smooth tissue at the ends of bones 2. the harder outer shell of bone 3. thickness portion which pushes the diaphysis away from the epiphysis (lengthens bone) 4. composed of small, needle-like pieces of bone called trabeculae

2. the harder outer shell of bone

What is the spongy (Cancellous) bone? 1. smooth tissue at the ends of bones 2. the harder outer shell of bone 3. thick portion which pushes the diaphysis away from the epiphysis (lengthens bone) 4. composed of small, needle-like pieces of bone called trabeculae

4. composed of small, needle-like pieces of bone called trabeculae

What is the function of osteoblasts? 1. thickness portion which pushes the diaphysis away from the epiphysis (lengthens bone) 2. They synthesize and secrete unmineralized osteoid & collagen, and pump calcium and phosphate salts into and out of bone tissue, building bones. 3. bone remodeling, bone growth, fracture repair, and removal of weakened bone matrix 4. They are bone-resorbing (dissolving)

2. They synthesize and secrete unmineralized osteoid & collagen, and pump calcium and phosphate salts into and out of bone tissue, building bones.
