• Definition: The combo of bones, joints, and muscles that lets us move, groove, and prove our athletic prowess!
• Why it matters: To get our game on in sports and exercise, we need to know how our bones and muscles dance together.

🔍 Joints = Body's Hinges

• Where: Places where two or more bones meet.
• How they work: Usually, it's like a twist or rotation between bones. Think of it as turning a doorknob!
• The force behind the twist: Muscles 💪, other body parts, gravity (yes, that thing keeping us grounded! 🌍), sports equipment, or even that friendly tackle in rugby.

• Non-axial (Gliding joints)

  • Example: Those tiny bones in your palm, called carpal bones.
  • What they do: Slide past each other like smooth dance moves. No specific rotation here.

• Uniaxial Joints

  • Types: Hinge (like the elbow) and Pivot (like the joint connecting your forearm bones).
  • Special move: They only rotate around one axis. It's like spinning on one foot!

• Biaxial Joints

  • Types: Condylar (like the knee) and Saddle (base of the thumb).
  • Special move: They got two rotation styles. It's like doing a two-step dance!

• Triaxial Joints

  • Example: Ball and socket joints, like our hip and shoulder.
  • Special move: They can rotate in three ways. Imagine dancing with full freedom in a mosh pit!
