Types
of Joints
Joints
come in many different varieties. While most joints allow much movement,
others have limited or no movement. The four different types of
joints that allow movement are the ball and
socket, hinge, pivot,
and glide joints. Attached to the joints are
ligaments, tendons, and cartilage to assist in the movement of your
body.
Ball
and Socket
The ball and socket joint allows your arms and hips to move in many
directions. Try it! Up Down, right left, and a full 360° rotation
give you a lot of freedom to get you where you want to go! Examples
include the shoulder and hip.
Hinge
Joint
The bones
in the knees, elbows, fingers, and toes move just like the hinges
on a door. If you're not quite clear on how they work, find the
closest door and swing it back and forth. Notice that movement is
somewhat limited, and it can only swing back and forth. Now try
the same thing on your knees, elbows, fingers, and toes.
Pivot Joint
The first two vertebrae in your neck and the joint beneath your
elbow move in a semicircle motion by twisting against eachother.
Try this first by holding your forearm and shoulder stationery,
and notice that the bottom part of your arm can move in a semi circle
back and forth. You can do the same thing with your vertebrae by
holding the lower part of your neck, and rotating you head.
Glide
Joint
The bones in the wrists and ankles slide against each other in a
gliding motion. Try out this joint by holding either right above
your wrist or ankle and moving it to the right and left, and up
and down. The gliding joint gives your wrists and ankles lots of
freedom so you can really move around
