function of the skeletal system
support and protection
support and weight baring: the skeleton system has been built to provide us with support with the vertebrae gives us posture and the limbs using gravity to keep us upright
protection- bone and are strong and they protect our vital organs and spinal cord calcium help the bone and to grow and be strong to prevent any form of damage to vital organs
attachment for skeletal muscles
bone provide attachment for muscles, when muscles contract they help us move
bones are also attached by joint providing a range of movement. by having a skeleton, muscle can move and function effectively.
bones attach to muscle through tendons
bony landmarks sites for attachment: condyles and tuberosity too provide attachment points
there are two main attachment sites:
insertion: an attachment site for a more moveable bone
origin: this is an attachment site for a less movable bone
source of blood cell production and storage of minerals
storage of minerals
mineral carry out the bodily function like thinking, breathing and moving around
within your bones you store calcium phosphor and magnesium
this are essential to help you perform sporting actions
source of blood cell production
within bone marrow white blood cells, red blood cells and platelets are produced
bones that contain marrow are the pelvis sternum the vertebrae and the calvicle
movement
to operate movement your skeletal system will use levers
levers is a long bone connected to the joint
muscle pull on the bone to provide movement for example: biceps attaching to the radius and contracts to move the elbow
this enable us to move in all directions and perform the action we need daily
without our skeletal system we will not have the structure to move into sporting position to be able to perform skills, in addition muscles will have nothing to pull against to create movement
