1. What is needed for osteoclast actiation: RANKL
2. What leads to primary osteoporosis: alterations in RANKL/OPG system lead to
dysregulation
3. Type IX collagen does what: The glue that holds together the type two collagen acaffold of articular
cartliage
4. osteosarcoma looks like what: most common malignant primary bone tumor. Has a moth eaten
pattern of bone destruction.
5. Giant cells in myelogenic tumors affect what gender more often: females
6. what is the hallmark of the OA process: Loss of proteoglycans from the articular cartilage
7. what is chronic fatigue syndrome: (Myalgic encephalomyelitis)- a debilitating and complex
disorder characterized by profound fatigue, musculoskeletal pain, cognitive impairment, unrefreshing sleep, impaired
neurologic energy production, and immune impairments.
8. what layer of the skin has langerhans-cells with dendritic processes and
immune function: epidermis
9. what is a vesicle: elevated, superficial, filled with serous fluid, less than 1cm. Ex-herpes, varicella
10. what is a bulla: vesicle greater than 1cm- Ex- blister
11. what are telangictasias: fine, irregular red lines produced by capillary dilation
12. Which type of collagen provides the scaffolding of articular cartilage?: Colla-
gen IX is the collagen, or scaffolding, that holds articular cartilage in place.
13. What is the term for a chronic inflammatory joint disease characterized by
stiffening and fusion of the spine and sacroiliac joints?: Ankylosing spondylitis is the result
of chronic inflammation in the spine and sacroiliac joints resulting in stiffening and fusion of the spine.
14. what is osteomyelitis: infection of bone
15. Describe the most likely route by which the microorganisms reached the
patient's bone.
Submit and Compare, displayed below: The microorganisms likely reached her bone by extension
from the nearby infected ulcer at the base of her big toe.
16. Name the microorganism that is most likely causing the osteomyelitis.
Submit and Compare, displayed below: staphylococcus aureus is the most common pathogen,
although many diabetic foot ulcers are polymicrobial infections.
17. Describe sequestrum.: Sequestrum is an area of necrotic bone that separates from the healthy bone.
