Quiz #4 Musculoskeletal Flashcards
By what gestation has fetus formed cartilage scale model of the skeleton?
3 months
When is bone growth most rapid?
infancy and adolescence
epiphyses
growth plates. Transverse disks at the ends of the long bones where lengthening of the long bones occurs.
curve of the spine at birth
single C shape
change in the spine at 3-4 months
raising the baby’s head from prone develops the anterior curve in the cervical neck region
change in the spine from 1 year-18 months
standing erect develops the anterior curve in the lumbar region
Diets rich in what and low in what in prevent obesity and promote bone mass accrual in children?
Dark green and deep yellow vegetables (greens, carrots, sweet potatoes)
Low in fried foods
What causes increased mobility in the joints of the pregnant woman?
Estrogen, relaxin, corticosteroids
Spine in the pregnant woman
lordosis increased, which compensates for enlarging fetus to shift weight back to lower extremities.
What postural changes in the pregnant woman compensate for lordosis?
Anterior flexion of the neck and slumping of the shoulder girdle. May put pressure on nerves and cause aching, numbness, and weakness in upper extremities.
bone remodeling
cyclic process of bone resorption and deposition.
Remodeling favors deposition until
skeletal maturity at 25-35 years- peak bone mass
After what age does loss of bone matrix occur more rapidly than new bone formation?
Age 40
Why do women have more osteoporosis than men?
For 5 years after menopause, women lack estrogen, leading to accelerated bone loss.
What causes decreased height with age?
- Shortening of the vertebral column due to loss of water content and thinning of the intervertebral disks
- Decrease in the height of individual vertebrae due to osteoporosis.
When does decrease in height begin/become signficant?
Begins in the 40s, becomes significant at age 60. Increaes in the 70s and 80s due osteoporitic collapse of the vertebrae
Postural changes with aging
kyphosis
backward head tilt to compensate for kyphosis
slight flexion of the hips and knees
In the 40s and 50s, weight….
begins to increase. Fat lost in the face and deposited in the abdomen and hips
In the 80s and 90s, fat
decreases in the periphery—especially apparent in the forearms.
Best preventative exercise for osteoporosis
Fast walking- faster decreases chance of a bone fracture.
Benefits of physical activity in the older adult
- Improves muscle strength
- Prevents falls
- Increases balance and posture control
- Decreases back pain
- Improves quality of life
Older adults with a physical activity training program with resistance, balance, and functional training showed
significant increases in strength, flexibility, HR after exercise, and balance.
BMD values in Af Am women
Much higher- lower risk of hip fracture
BMD in white women
In femoral neck at the hip joint, BMD peaks earlier in whites than other race groups. Weight bearing exercise is imperative.
Subjective data for musculoskeletal system
- Joint pain or problems
- Knee joint
- Muscles
- Bones
- Functional ADL
- Patient-centered care
Pain in bilateral joints may indicate
Rheumatoid arthritis
rheumatoid arthritis S+S
Bilateral joint pain, very tender
Worse in the morning and after rest
Joint pain that is worse later in the day
osteoarhritis
