Chapter 47 mobility and immobility Flashcards
Visible aspect and contributes to self-worth and well-being
Movement
Used to show self-defense, perform activities of daily living (ADLs) and recreational activities
Mobility
Coordinated efforts of the musculoskeletal and nervous system
Body mechanics
Reduces strain, maintains muscle tone, comfort, conserves energy
Body alignment
Required to maintain a static position
Balance
Force that occurs in a direction to oppose movement
Friction
Contribute to height
Long bones
Occur in clusters (carpal bones in the foot)
Short bones
Provide structural contour (skull)
Flat bones
Make up the vertebral column and some bones of the skull
Irregular bones
Caused by weakened bone tissue
Pathological fractures
Bones jointed by bones with no movement
Synostosis joint
Unites bony components
Cartilaginous joint
joint in which a ligament unites two bony surfaces (paired bones of the lower leg)
Fibrous joint
Ball and Socket Joint (hip)
Synovial joint
Fibrous tissue that connect ones an cartilages
Ligaments
Connect muscle to bone
Tendons
Nonvascular, supporting tissue (joints and thorax)
Cartilage
Increased muscle contraction causes muscle shortening resulting in movement
concentric tension
Helps control the speed and direction of movement
Eccentric tension
Active movement between concentric and eccentric muscle actions
Isotonic contraction
Causes an increase in muscle tension or muscle work but no shortening or active movement
Isometric contraction
Inducing or compelling force
Leverage
Position of the body in relation to the surrounding space
Posture
