Label the bones on the body
Ok
What are the main functions of the skelteton
- Support
- Protection
- Movement
- Posture and structural shape
- Mineral storage
- Blood cell production
Describe how the skeleton provides support
It give the body support, enabling us to stand. The bones are held together by ligaments. The skeleton provides a framework for the muscles, which are attached to bones by tendons
What are ligaments for
For stability
Go bone to bone
What are tendons for
Movement
Describe how the skeleton provides protection
Some of our body parts, such as the brain, are very delicate so need protection. Bones can protect body parts from impacts and injuries.
Describe how the skeleton allows movement
The skeleton has many different joints. At joints, muscles and bones form levers to allow sporting movements.
Describe how the skeleton provides posture and structural shape
The skeleton acts as a framework. Muscles are firmly attached to bones forming our body shape and holds us upright
Describe how the skeleton provides mineral storage
The minerals in your bones serve two main functions.
Minerals transform spongy bone matrix into a rigid structure and in turn increase density and strength.
Your bones also function as a mineral storage depot, releasing dissolved calcium, phosphorus and magnesium into your bloodstream when needed.
Describe how the skeleton allows blood cell production
The ends of long bones and some other bones including ribs, humorous, femur and even vertebrae bones contain red bone marrow.
This is where the red blood cells are produced which carry oxygen.
Also produce white blood cells to combat illness
And platelets for clotting and healing.
An example of how the body provides support
In gymnastics, the vertebrae supports the body and provides attachment for muscles to hold a handstand.
An example of how the body provides protection
In boxing, the ribs protect the heart and lungs from impact.
An example of how the body allows movement
In football, the femur, tibia, and patella work together at the knee joint to allow a player to kick the ball.
An example of how the body provides posture and structural shape
In ballet, the vertebrae helps the dancer keep an upright posture and balanced position.
An example of how the body allows blood cell production
In long-distance running, the femur and pelvis produce red blood cells in the bone marrow to carry oxygen to the muscles.
An example of how the body provides mineral storage
In weightlifting, the humerus and femur store calcium to keep bones strong for lifting heavy weights.
What are the two different minerals stored on the body
Calcium and phosphorus
Where does the production of blood cells and platelets take place
In the bone marrow
What are our muscles are attached to
Bones, which are jointed. When the muscles contract the bones move
What happens to the bones connected to the muscles when the muscles contract
The bones move
What is the ‘rule’ with joints about mobility and stability
Can’t have both
Either sacrifice mobility for stability or vice versa

How many bones are in the knee joint

What bones are in the knee joint
Tibia and femur
