Section 1 + Section 4
Where does hematopoiesis occur, and what cells are formed there?
What is Red bone marrow; forms red and white blood cells and platelets?
If the periosteum were damaged, what problems might occur with bone healing?
What is Bone healing and nutrient delivery would be impaired?
If osteoclasts became overactive, what condition could develop?
What is Osteoporosis?
Which hormone causes calcium to move into bone?
What is Calcitonin?
Why are older women more prone to osteoporosis?
What is Loss of estrogen, which helps maintain bone density?
If a bone could no longer store calcium, what two systems would be immediately affected?
What is Nervous and muscular systems?
How does spongy bone help reduce the weight of a bone while maintaining strength?
What is Spongy bone has open spaces that lighten the bone while supporting stress from multiple directions?
Which bone cells are most active during healing after a fracture?
What is Osteoblasts?
What would happen if someone lacked Vitamin D?
What is Bones would soften (rickets/osteomalacia) due to poor calcium absorption?
What can be done to prevent bone density loss?
What is Adequate calcium and vitamin D intake, weight-bearing exercise, hormone balance?
Which function of bone helps maintain blood pH?
What is Acid-base balance?
Which part of the bone would you find yellow marrow in an adult?
What is In the diaphysis of long bones?
How do osteoblasts and osteoclasts work together to maintain homeostasis?
What is Osteoblasts build new bone; osteoclasts break down old bone to maintain balance?
If a fracture occurs at the epiphyseal plate, what long-term effect might that have on growth?
What is The bone might stop growing in length or grow unevenly?
What would happen if the canaliculi were blocked?
What is Nutrients and waste could not move between bone cells, leading to cell death?
What would happen if the epiphyseal plate closed too early in a child?
What is Premature stunting of growth?
How does exercise influence bone strength?
What is Exercise increases stress on bone, promoting strength and density?
What’s the difference between a closed reduction and an open reduction?
What is Closed reduction: non-surgical; Open reduction: surgical using plates or screws?
Why is it important for compact bone to have a strong blood supply?
What is Blood supply delivers nutrients and removes waste from living bone cells?
Compare intramembranous and endochondral ossification in your own words.
What is Intramembranous forms flat bones from membranes; endochondral forms long bones from cartilage?
What happens to bones under zero gravity (spaceflight)?
What is Bones lose density and weaken due to lack of stress?
