Musculo-skeletal System Flashcards
What is the musculo skeletal system
Includes all the bones from the body and the muscles that are attached. Working together joints bones and muscles
Why is the muscle-skeletal system important in sport
Keep as stable
Give us posture
Give us protection
And movement
What are the 5 functions of the skeleton
Protection Muscle attachment Joints for movement Blood cell production Storing minerals
How does our skeleton protect our vital organs in sport
The skull protects the brain, the spine protects the spinal cord, and the ribs protect the internal organs, including heart. They act as cages around important body parts. Sometimes there is extra protection
What is the benefit of muscle attachment in sport
Bones provide a strong framework that the muscle can attach to. The muscles are attached by the tendons and the bones act as anchors that the muscles pull as they move
Why are joints important in sport
Joints let the body make a variety of movements. Joints work as levers as small movement at the top of the leg makes a big movement ate the bottom allowing to kick a football. Without joints we could move so couldn’t play football
Why is calcium and phosphorus important for sportsmen.
The bones act as a store for calcium and phosphorus, two mineral that are vital for development and maintaining strong and healthy bones that are not brittle so they don’t break putting us out of sport. phosphorus also helps to reduce muscle pain after a hard workout
Why is red and white blood cells important in sport
Some bones have hollow centres that hold bone marrow. Bone marrow makes must of the cells of the blood: red blood cells, white blood cells and platelets.
Infection- more white blood cells (stop infections so carry on playing)
Is the red blood cell count goes down- produce more( need oxygen)
Cut- more platelets (abrasion clog up and carry on)
