• What system is the focus of this podcast?

  Skeletal system
• Why is it important to know how the skeletal and muscular systems work together?

  They enable movement in the body
• How many main functions are associated with the skeletal system?

  Five
• What is produced inside the bones of the skeletal system?

  Blood cells
• What connects muscles to bones?

  Tendons
• What is the role of connective tissue in the skeletal system?

  It attaches muscles to bones
• What mineral is stored in the skeletal system for strong bones?

  Calcium
• What does the skeletal system protect?

  Vital organs
• What is a mnemonic to remember the functions of the skeletal system?

  Bones make moving joints possible
• What are the four main types of bones?

  Long, short, flat, irregular
• What type of bone is the femur?

  Long bone
• What do short bones help with?

  Weight bearing
• What is the function of flat bones?

  Protection and muscle attachment
• What are irregular bones shaped like?

  Unusual shapes
• What type of joint allows for rotation?

  Pivot joint
• What do condyloid joints allow for?

  Circular movement
• What is the structure of a ball and socket joint?

  Ball fits into a dome-like shape
• What connects bones to other bones?

  Ligaments
• What is flexion in terms of joint movement?

  Decreasing the angle of a joint
• What is extension in joint movement?

  Increasing the angle of a joint
• What is dorsiflexion?

  Foot raised upwards at the ankle
• What is plantar flexion?

  Foot pointed downwards at the ankle
• What does abduction mean in joint movement?

  Moving a body part away from the body
• What does adduction mean in joint movement?

  Moving a body part towards the center line
• What is rotation in terms of body movement?

  Twisting action around a joint
• What is circumduction?

  Combination of flexion, extension, abduction, adduction
• What are the main functions of the skeletal system?

  • Blood cell production
  • Muscle attachment
  • Mineral storage
  • Joint formation
  • Protection of vital organs
• What are the different types of bones and their characteristics?

  • Long bones: Longer than wide (e.g., femur)
  • Short bones: Box-like shape (e.g., carpals)
  • Flat bones: Thin plates (e.g., sternum)
  • Irregular bones: Unusual shapes (e.g., vertebrae)
• What are the four main types of joints and their functions?

  • Pivot joints: Allow rotation (e.g., vertebrae)
  • Hinge joints: Allow flexion and extension (e.g., knee)
  • Condyloid joints: Allow circular movement (e.g., wrist)
  • Ball and socket joints: Allow rotation (e.g., shoulder)
• What are the main types of movements associated with the skeletal system?

  • Flexion: Decreasing angle of a joint
  • Extension: Increasing angle of a joint
  • Dorsiflexion: Foot raised upwards
  • Plantar flexion: Foot pointed downwards
  • Abduction: Moving away from the body
  • Adduction: Moving towards the body
  • Rotation: Twisting action
  • Circumduction: Circular movement
• What is the difference between tendons and ligaments?

  • Tendons: Connect muscles to bones
  • Ligaments: Connect bones to other bones
