Skeletal

• What substance is produced by synovial membranes to nourish bones?

  Synovial fluid
• What is the role of synovial fluid in the joints?

  It provides joint protection and keeps it healthy, nourished, and lubricated.
• How can one ensure a constant flow of synovial fluid in the joints?

  By maintaining a healthy and regular exercise routine.
• How does increased synovial fluid production affect joint mobility?

  It increases mobility within the joint.
• What happens to joints after periods of inactivity?

  They feel stiffer and lose some of their range of motion.
• What type of exercises increase bone density?

  High impact, weight-bearing exercises.
• What cells are produced in response to strain on bones during exercise?

  Osteoblasts
• Why are stronger ligaments important for certain populations?

  They provide more stability and reduce the risk of misalignment of joints.
• Why do ligaments take longer to show benefits from exercise?

  Because they have very little to no blood supply.
• What are the four main benefits of physical exercise on the skeletal system and bone health?

  • Increased synovial fluid production
  • Increased range of motion
  • Increased bone density
  • Stronger ligaments
• What is one function of the skeletal system related to movement?

  It prevents friction between the femur and tibia, allowing free movement at the knee.
• What is one benefit of exercise on bone health?

  Stronger and more durable bones.
• How does exercise affect mineral storage in bones?

  It increases mineral storage and calcium absorption.
• What is one effect of exercise on ligaments and connective tissue?

  Stronger ligaments and increased joint stability.
• What is one of the benefits of exercise in relation to osteoporosis?

  It reduces the risk of osteoporosis, arthritis, fractures, and broken bones.
• How does exercise impact posture?

  It improves posture.
• What effect does exercise have on cartilage?

  It increases cartilage thickness and strength.
• What is the relationship between exercise and synovial fluid?

  Exercise increases the production of synovial fluid.
• What are the impacts of physical activity and sport on the skeletal system?

  They can have positive and negative impacts.
• What are the positive impacts of physical activity on the skeletal system?

  • Stronger, thicker bones
  • Increased stability and stronger joints
  • Prevention of osteoporosis
  • Reduced risk of osteoarthritis
• What is one positive impact of physical activity on bones?

  Stronger, thicker bones.
• What causes stronger, thicker bones?

  High impact or weight-bearing exercise.
• What is increased bone density a result of?

  High impact or weight-bearing exercise.
• How does increased bone density benefit the skeletal system?

  It prevents and protects from injury to bones.
• What is another positive impact of physical activity on joints?

  Increased stability and stronger joints.
• What contributes to stronger joints?

  Stronger ligaments and tendons.
• What does increased stability in joints help prevent?

  It helps prevent sprains and dislocations.
• What condition does physical activity help prevent related to bone density?

  Osteoporosis.
• What is osteoporosis characterized by?

  Reduced bone density and weakening with age.
• Who can be affected by osteoporosis?

  Both young people and older people.
• What is one of the benefits of exercise related to osteoarthritis?

  It reduces the risk of osteoarthritis.
• How does exercise affect cartilage in joints?

  Exercise thickens articular (hyaline) cartilage.
• What is produced more due to exercise that benefits joints?

  More synovial fluid is produced.
• How does increased synovial fluid benefit joints?

  It reduces friction and wear and tear at joints.
• What is one benefit of joints being better able to absorb shock?

  It reduces the risk of injury during physical activity.
• What are the negative impacts of physical activity on the skeletal system?

  • Formation of bone spurs
  • Chronic overuse injuries (e.g., tendonitis)
  • Acute impact injuries (e.g., fractures)
• What is a risk factor associated with high impact activities?

  Formation of bone spurs.
• What do chronic overuse injuries result from?

  Repetitive actions that cause damage.
• What is an example of a tendonitis injury?

  Tennis or golfer's elbow.
• What is an example of a stress fracture?

  Shin splints.
