Types of joints movements and articulation

Types of joints movements and articulation

There are six main types of joint movements, each of which involves a specific type of articulation between bones in the human body:

  1. Flexion: This movement decreases the angle between two bones, such as bending the elbow or knee.
  2. Extension: This movement increases the angle between two bones, such as straightening the elbow or knee.
  3. Abduction: This movement moves a bone away from the midline of the body, such as lifting the arm away from the side of the body.
  4. Adduction: This movement moves a bone toward the midline of the body, such as lowering the arm to the side of the body.
  5. Rotation: This movement involves rotating a bone around its axis, such as turning the head from side to side.
  6. Circumduction: This movement involves a combination of flexion, extension, abduction, and adduction, such as when drawing a circle with the arm.

These joint movements occur through different types of articulations between bones, including:

  1. Hinge Joint: These joints allow for flexion and extension movements and occur where the convex surface of one bone fits into the concave surface of another, such as in the elbow and knee.
  2. Ball-and-Socket Joint: These joints allow for the greatest range of motion and occur where the rounded end of one bone fits into a cup-shaped depression of another, such as in the hip and shoulder.
  3. Pivot Joint: These joints allow for rotation movements and occur where a ring-like structure rotates around a pivot, such as in the neck.
  4. Condyloid Joint: These joints allow for flexion, extension, abduction, adduction, and circumduction movements and occur where an oval-shaped end of one bone fits into a similarly shaped depression of another, such as in the wrist.
  5. Saddle Joint: These joints allow for flexion, extension, abduction, adduction, and circumduction movements and occur where the concave and convex surfaces of two bones interlock, such as in the thumb.
  6. Gliding Joint: These joints allow for slight movements and occur where the flat surfaces of two bones slide against each other, such as in the joints between the vertebrae of the spine.
