Quick Flash 🌟

Your body is like a well-oiled machine with all sorts of joints that help you move, dance, and even do the floss! Let's break down how these "motion managers" work!

What even is range of motion (ROM)? 🤷‍♀️

It's like the number of dance moves a joint can pull off! The structure of a joint decides what moves it can (or can't) do.

Key players in joint structure 🦴

Ligamentous Joint Capsule & Ligaments: Think of them as the bouncers at a club; they determine who gets in and out, or in our case, which movements are allowed!

Let's talk joints 💪

  • Elbow & Knee Joints

    • Type: Hinge Joints
    • Moves
      • Flexion: Like bending to pet a cute doggo 🐶
      • Extension: Stretching out after a long nap 😴
  • Hip Joint

    • Type: Ball-and-Socket Joint
    • Moves
      • Protract & Retract: Think forward and backward swing in a dance 💃
      • Abduct & Adduct: Moving away & towards the body (like doing a star jump! 🌟)
      • Rotate: Like twirling a hula hoop! 🪅

Real World Example: Imagine the hinge joint as a door hinge. It only opens and closes in one direction. But the ball-and-socket joint? It's like those spinning tops that move in every direction!
