Hyaline Cartilage that covers the articular surface
articular cartilage
white membrane that covers bone
periosteum
cartilage maintenance and repair
glucosamine
reduces wear and tear
chondroitin sulfate
Bacterial infection of bone and marrow
Osteomyelitis
Similar demineralization to rickets but does not have skeletal change, rather they become more susceptible to bone fracture.
Osteo Malacia
Loss of minerals due to vitamin D deficiency (bow legs)
Rickets
Bone as strong as 1/3 the weight of iron
true

false
it takes how many months for a bone to heal
6-12 weeks
Identify the functions of the bone and describe them
- Support, without it we couldn’t stand
- Protection, protecting organs
- Movement, facilitate movement
- storing minerals, calcium
- Hematopoiesis
Compare and contrast yellow and red marrow
Red bone marrow is active in hematopoiesis while yellow is inactive. Infants have more red marrow. yellow marrow is saturated with fat.
