Mobility Flashcards
What is a ball and socket joint?
Rounded head of one bone fits into the cup-like cavity in the other bone (shoulder)
What is a condyloid joint?
When the oval head of one bone fits into a shallow cavity of another bone (wrist joint or joints connecting the finger to the palm)
What is a pivot joint?
A ring-like structure that turns on a pivot, such as the joints between the atlas and axis of the neck and between the proximal ends of the radius and ulna at the wrist
What is a saddle joint?
Have bone surfaces that are convex on on side and concave on the other side such as the joint between the trapezium and metacarpal of the thumb
What is osteoporosis?
Condition where bone destruction exceeds bone formation and results in thin, porous bones that fracture easily
What does the skeletal system provide storage for?
-Calcium
-Phosphorus
-Magnesium
-Iron
-Lipids
What does the red bone marrow produce?
Red bone marrow in center of bones produces red blood cells, platelets, and macrophages
How do muscle assist with thermoregulation?
Generate heat by contracting muscles
What is a pivot disc?
Used for a client who has strength in lower extremities and is able to stand up
What is atelectasis?
Collapse or closure of a lung resulting in reduced or absent gas exhange
What are tendons?
They attach muscle to bone
What are ligaments?
Bones to other bones
Why is mobility important?
-use it or lose it
-independence
-health & fitness
- self esteem, body image and self concept
What does the muscular system do?
Permits movement of the body, maintains posture and heat production
What are the 3 types of muscles?
Skeletal, cardiac, smooth/visceral
What are the 3 types of exercises?
Isotonic, Isometric, Isokinetic
What is isotonic exercise?
Involves muscle shortening & active movement; ROM muscle extension and shortening
What is isometric exercise?
Involves muscle contraction WITHOUT shortening; tightening muscles (isolation of contraction of muscles ex. Stomach)
What is isokinetic exercise?
Involves muscle contractions with RESISTANCE (lifting weights)
Benefits of exercise for the heart?
Heart pumps efficiently, increased HR, decreased BP and increased blood flow to body
Benefits of exercise for Respiratory?
Increased oxygen to muscles and promotes gas exchange
Benefits of exercise for musculoskeletal?
Prevents bone loss, tones muscles, increase muscle mass and flexibility and longer life expectancy
Benefits of exercise to gastro?
Increased appetite and promotes movements of stools
Benefits of exercise to urinary?
Increased blood circulation to kidneys and promotes balance of body fluids
