Joints

The skeleton is made up of bones which meet at JOINTS. There are several different types of joints.

BALL AND SOCKET JOINT    

the joints at the shoulder and hips are ball and socket joints. 
They allow movement in different directions

HINGE JOINTS    

The joint at the elbow is a hinge joint.  

It allows movement up and down, but not side to side.

Gliding Joints

Also known as a plane joint.

Allow the bones to glide past one another in any direction along the plane of the joint — up and down, left and right, and diagonally.

Pivot Joints

A pivot joint is a type of synovial joint that rotates. 

Two examples of pivot joints in your body are the pivot joint in your neck that allows your head to rotate and the pivot joints between the radius and ulna that rotate your forearm.

You have 650 muscles in your body

Joints and Muscles work together to allow you to move

Muscles can only contract (get shorter) or Relax (when they can be pulled longer again).

What are your muscles doing when you bend your arm? Are they contracting or relaxing?

​

The biceps and triceps are an antagonistic pair of muscles. 

What does this mean?

Antagonistic pairs 

Muscles can only pull, not push. So one muscle pulls the bone one way, and the paired muscle pulls it back again.

Antagonistic Pairs of muscles. 

Muscles that work like this are called antagonistic pairs. ... In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. 

Antagonistic Pairs of muscles. 

The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

Respiration and Muscles 

Contracting is hard work for muscles. They get hot. Respiration releases energy so that they can work.
