musc/skel Flashcards
Musculoskeletal systems consist of:
of bones, muscles, and joints
Muscles account for 40% - 50% of body, and when contracting they produce movement
Skeletal muscles produce which type of movement? (p. 578)
Flexion Extension Abduction Adduction Pronation Supination Circumduction Inversion Eversion Rotation Protraction Elevation Depression
Muscles vary in size and strength in different people due to :
genetic programming, nutrition and exercise.
Osteoporosis:
– the effect of gradual loss of bone density
Women more than men d/t:
5 years after menopause lack of estrogen leads to accelerated bone loss
Postural changes evident with:
aging, especially height (decrease) why?
Shortening of vertebral caused by loss of water content and thinning disk
Sedentary lifestyle:
quickens musculoskeletal changes in the aging
Physical exercise increases:
skeletal mass and helps prevent/delay osteoporosis
Physical exercise can delay or prevent:
bone loss in postmenopausal women.
Best way to prevent osteoporosis:
Fast walking (hip fracture prevention)
Physical activity improves muscle strength to prevent:
falls, increase balance, posture control, decrease back pain, increase quality of life
he aging adult who participates in physical activity program with:
resistance, balance, and functional training has significant increase in strength, flexibility.
Flexibility and balance remained improved at the end of 3 month of detraining.
Joint pain/loss of function, most common with:
musculoskeletal concern to seek care
RA:
Pain worse in morning when arising
Stiffness occurs in the morning & after rest periods
Movement decreases pain
Osteoarthritis:
Is worse later in day
