where two or more bones come together
joints
immoveable or only slightly moveable, fibrous tissue or cartilage unite the bones
nonsynovial joints
freely moveable, bones are separate from each other and enclosed in a joint cavity that is filled with synovial fluid
synovial joints
covers the surface of opposing bones, cushions the bones, and creates a smooth surface that facilitates movement
cartilage

produce movement when they contract

what are the developmental considerations for infants and children?
Bone growth – from in utero through to adolescence when a rapid growth
spurt occurs
* Long bones grow in 2 dimensions: width (diameter) and length
* Skeletal contour changes noted at the vertebral column
* Development of dysplasia of the hip (DDH) - congenital abnormalities of the
hip joint
* Infants should be examined periodically until they are walking
independently
* Several risk factors. Examples: having a first=degree relative with DDH,
breech delivery etc.
* Growing Pains - Noninflammatory pain syndrome affecting children between
ages 3-12
what are the developmental considerations for pregnancy?
Increased joint mobility occurs
due to increased levels of
circulating hormones such as
estrogen, relaxing etc.
* Change in posture - lordosis which
compensates for the growing
fetus
Reabsorption of bone occurs more rapidly then deposition
after the age of 40 years
osteoporosis

water content, thinning of the vertebral discs
decreased height

palpable
* Note: a small amount of fluid is present in the normal joint but it is
not palpable
what are the abnormal findings for palpation of the musculoskeletal system?
Warmth, tenderness, palpable fluid, tenderness, thickened
synovial membrane
