2110 Pathology of MS System, chapter 13
|More than 50% of injuries in the US occur to what system?||Musculoskeletal System|
|3 weeks of bed rest have a more profound impact on physical work capacity than 3 decades of aging. T or F?||True|
|When do women double their rate of injury?|| During ovulation, when estrogen levels are the highest. |
Should train differently during this time.
|At what rate do men increase their muscle mass compared to women?|| Twice as much.|
They also experience larger losses.
|T or F? Vasodilation allows for the WBC to migrate to the periphery of the vessel in margination.||False - vasocontriction allows for margination to occur.|
|What is it called when WBC adhere to the walls of the damaged capillary?||Pavementing|
|Diapedesis?||Increased permeability, allowing for WBC to squeeze through blood vessel wall.|
|How do WBCs navigate to injury sites?||Chemotaxis|
|Increased muscle tone/spasm and loss of function indicate acute or chronic inflammation?||acute|
|What is an age related loss in muscle mass, strength and endurance accompanied by changes in the metabolic quality of skeletal muscle?||Sarcopenia|
|How much muscle mass do women and men lose/year?|| women > age 40 = 4-6%|
men > age 60 = 4-6%
|What is the pathogenisis of sarcopenia?|| Decreased capacity among motor neurons to innervate regenerating fibers.|
Not enough protein in diet.
|What are some pathologies affected by sarcopenia?|| DM II|
|Name a few PT interventions for sarcopenia?|| Strength|
|What does proprioception provide?|| Sense of joint position and movement.|
Decreases w/ age.
| 1. Mechanical stress|
2. Ca/phosphate levels and
3. Hormone levels influence what?
|At what age does bone density reach its peak?|| 20's.|
Remains stable for 20 years.
|Does each muscle contain type I & II fibers?||yes|
|T or F? Endurance training can reverse 100% of the loss of CV capacity.||true|
|Is there benefit to strength training > 4x/wk?||no|
|6 exercise guidelines?|| 1. Get a physical|
2. Aerobic ex
3. Warm up/cool down
4. Strength training - low load to begin
5. Full ROM w/ all muscles
6. Stop of injury occurs
|What are the 2 most serious MS diseases?|| CA|
|Is metastatic disease of the MS relatively common?||yes b/c bone provides fertile ground for growth.|
|What are the 3 primary cancer sites that lead to metastatic bone disease?|| lung|
|What is the major manifestation of bone CA?|| Pain, mainly on wb and at night|
Back pain, too
|What causes the pain present in bone CA?|| stretching the periosteum|
irritation of nerve root
|Name the condition of infection of the bone?||osteomyelitis|
|Most common infectious agent that cause of ostemyelitis?||bacteria|
|T or F? Bacteria can travel through the blood to infect bone.||true|
|Infection in the pelvic floor, kidneys, colon and bladder refers pain where?|| Hip/thigh|
