chapter 9 joints Flashcards
what are the 4 system that interact
Muscles attach to bones
Bones are controlled by endocrine system
Digestive and urinary systems provide calcium and phosphate minerals to bones for growth
Skeleton serves as a reserve for calcium, phosphate, and other minerals
what are the factors that involve in bones
Age
Physical stresses
Hormone levels
Calcium and phosphorus uptake and excretion
Genetic or environmental factors
bone remodeling involves
Bone formation (osteoblasts)
And bone recycling (osteoclasts
what are the degenrative changes
Rheumatoid arthritis
An inflammatory condition
Immune system attacks joint tissues
Gouty arthritis
Crystals of uric acid form within synovial fluid
what is osteoarthritis
Caused by wear and tear of joint surfaces, or genetic factors affecting collagen formation
Generally affects people over age 60
what is rheumatism
Pain and stiffness in musculoskeletal system
defn the acetabular labrum
Rim of fibrocartilage
Increases depth of joint cavity
Seals in synovial fluid
defn the shoulder joint
Greatest range of motion of any joint
Most frequently dislocated joint
Supported by skeletal muscles, tendons, and ligaments
def the gland labrum
Rim of fibrocartilage
Extends beyond bony rim and deepens socket of glenoid cavity
which joint is shoulder separation
Partial or complete dislocation of acromioclavicular joint
what is the complex of the knee joint
Transfers weight from femur to tibia
Three articulations
Two femur–tibia articulations
At medial and lateral condyles
One between patella and patellar surface of femur
