1.protection of vital organs, 2.muscle attachment,3.joint for movement, 4.Storage of calcium and phosphorus, 5.platelets red and white blood cell production
e.g The cranium protects the brain /fall over on your back because of football protection from being winded.
e.g when your spinning,dancing/need strong point to attach to bones which provide framework for muscles
kick a ball This sort of lever turns small movements in your leg muscle into larger movements at the end of the leg
helps with recovery/ vital for developing and maintaining strong and healthy bones
if you cut your finger on a hockey stick, it fights bacteria from getting inside
joints allow for a variety of movement and work together with bones and muscles to form levers
flat bone,long bone,short bone,irregular bone
quite large and usually protect vital organs, e.g. ribs
enable large movement e.e femur
enable finer, controlled movements e.g phalanges
specifically shaped to protect, e.g. vertebrate
generate movement, strength and speed as levers and are pulled by different muscles to make the body move.
Tarsals, where is the body weight on the foot when standing or running
protect vital organs, especially in Contact sports, they offer muscle attachment for movement
they protection example vertebrate to spinal cord.
Located on upper arm, long bone,leverage, Bowling ball cricket bowl
Located on wrist, short bone, weight-bearing used in gymnastics handstands
located on knee, short bone, weight-bearing used in swimming
Located on chest, flat bone, protective organs, boxing
located on head, long bone, protect brain, rugby
located on leg, lone, generates movement, running
located on hip, short bone, weight bearing, Athletics
(neck,atlas-axis) only do rotation
(hip-shoulder) movement possibilities flexion and extension abduction and abduction rotation and circumduction
(knee,elbow,ankle) knee+elbow= flexion and plantar affection
ankle= Extension and Dorsi flexion
(wrist) flexion and extension adduction and abduction, Circumduction
closing a joint e.g wrist movement during a basketball throw
opening a joint e.g kicking a ball
Moving towards e.g swinging a golf club
Moving away, taking back a tennis racket before swinging it
Clockwise or anticlockwise movement, e.g. the leg movement
during a turnout in ballet.
Movement of a limb, hand or foot in a circular motion, e.g.
to bowl a cricket ball.
Extension at the ankle, e.g. pointing the toes
during gymnastics.
Flexion at the ankle, e.g. lifting the toes
during gymnastics.
hold bones together to ristrict how much joints can move and helps maintain rhe stability of the skeleton and prevents disclocation of thr joint
attach muscles to bones (or to other muscles) to allow bones to move when muscles contract.
attached to bones and they work whenever we want them to example biceps and triceps/under our conscious control
e.g (Biceps are used for tennis if you use your phone to hit the ball elbow flexion)
We cannot control them instead they are controlled automatically by the involuntary nervous system/found on the walls of the internal organs in the digestive,circulatory, Uranian systems
During exercise involuntary smooth muscle makes up the blood vessels contract in order to redistribute blood to where it needs it most
Forms the wall of the heart chambers contracts without conscious thought
Vital in sport because it makes the heart pump. Fitness training will strengthen cardiac muscles making the heart more efficient at pumping blood around the body.
they work together to allow movement which occurs at the joints. One system couldn't work without the other.
TYPE IIX - Used in anaerobic work. Can generate a much greater force than other
fibre types but fatigue quickly. Useful in short bursts of exercise, e.g. a 100 m sprint.
used in anaerobic work for e.g 400m and 800m
used in long distance as can go for longer without fatiguing
pairs of muscles at work against each other
plantar flexion to dorsi flexion and quadriceps and hamstrings act on the knee
gastrocnemius and tibialis anterior acting at the ankle
biceps and triceps acting at the elbow
hip flexors and gluteus maximus acting at the hip
adduction and flexion (horizontally) at the shoulder,
e.g. during a forehand drive in tennis.
flexion, extension, abduction
or circumduction at the shoulder.
E.g. during front crawl in swimming.
biceps.
BICEPS - flexion at the elbow,
e.g. when curling weights.
rotation or flexion
at the waist, e.g. preparing to throw a discus
flextion at the waist e.g doing a sit up
flexion of the leg at the hip,
e.g. lifting the knee when sprinting.
extension at the knee,
e.g. when performing a drop kick in rugby.
TIBIALIS ANTERIOR - dorsi-flexion at the ankle,
e.g. during a heel side turn in snowboarding.
