Parts of a vertebra
Atlas and axis
Taska. How do we warm up our neck joint
before physical activity?
b. What is the job/function of each?
Why the spine is regarded as weak for some activities
• The shape of the spine is fairly thin for the weight it is expected to carry and support.
• Additional activity where we have to lift or carry can be dangerous.
• If we break our spine we will damage our spinal cord.
• This can result in paralysis or death.
Why the spine is regarded as weak for some activities
• Look at the shape of the neck.
• It is particularly vulnerable to injury.
• Lower down, the spine is supported by ribs and it becomes thicker.
Task
1. Copy the table below and add 2 neck-related examples of your own.
Sport incident Possible result
Rugby Collapsed scrum
Body weight lands on your neck at a band angle and breaks it
Why the spine is regarded as weak for some activities
• Look at the movement of the back it looks very flexible
• ….but in fact it’s not!
Look at the movement of the back it looks very flexible
• Between each vertebra you have a disc of cartilage.
• When we bend there is a small amount of movement between each one.
• Many vertebrae means there is a lot of movement.
Task1. When we play golf, the spine seems to
move a lot. How can this be?
Look at the movement of the back it looks very flexible
• If you lift something badly or bend over or twist unexpectedly you can tear or strain the ligaments holding the vertebrae.
• This is called a ‘slipped disc’.
Task1. List four functions of the skeleton.
2. Using these four functions, explain how the vertebrae help fulfil those functions.
