Joints: A Meeting Place for Bones

What are joints? • Joints are found at the places where bones meet • They allow for the skeleton to be flexible, otherwise we wouldn’t be able to move!

5 Types of Moveable Joints

Fun Fact • Some joints don’t move at all! • Immovable joints (known as fixed joints) don’t move at all • Where do you think you can find these joints? – Turn and talk with someone sitting near you

Where do you think you can find immovable (fixed) joints? Answer: In your skull • The top of your skull is actually made up of three bony plates. • These plates fused, or joined, together when you were just a few months old in order to protect your brain.

Types of Joints Note Taking Sheet • As we go through the five types of joints, take careful notes

Ball and Socket Joints • It is named for the way it looks: a rounded ball fits into a cup-like socket • Allows you to move in a circle (like a joystick) • Found at your hip and shoulder

Ball and Socket Joint Example

Gliding Joints • Two bone plates glide, or slide, against one another • This helps to make movement easier • Found at your ankles and wrist

Gliding Joint Example

Saddle Joints • Allows for two different types of movement • They rock back and forth and from side to side • The only place they are found is in your thumbs!

Saddle Joint Example

Hinge Joints • This joint moves like a door hinge • It can only swing back and forth • Found at your elbow and knee

Hinge Joint Example

Pivot Joints • This joint lets you rotate from side to side • Works just like the hands on a clock, but CANNOT go all the way around • Found in your neck
