Anatomy & Physiology (PAPER 1) Flashcards
What are the functions of the skeletal system?
Blood cell production
Muscle attachment
Mineral storage
Joints for movement
Protection of vital organs
where are red blood cells, white blood cells and platelets are produced
in the bone marrow contained within certain bones
what do red blood cells do?
Red blood cells carry oxygen to working muscles.
what do white blood cells do?
White blood cells fight infection
what do platlets do?
platelets help blood to clot following an injury.
what do bones provide for muscles to attach via tendons?
Bones provide a surface for muscles to attach to via tendons.
Bones act as …………. that muscles can ……… on as they move.
Bones act as anchors that muscles can pull on as they move.
what minerals are stored within the bones?
Calcium and phosphorus are stored within the bones.
what are Calcium and phosphorus essential for?
These minerals are essential for vital body functions, strong teeth and bones and calcium is involved in muscular contractions.
why is mineral storage important for sport?
because strong bones and muscles help athletes performance
what is a joint?
A joint is a point where two or more bones meet and allow for movement to take place.
why do you need joints for movemnt in sport?
E.g. A rower needs the bones in her arms (Humerus, Radius & Ulna) to join at her elbow creating the movement needed to pull an oar.
what do many bones act as?
Many bones act as a soft rigid shell.
what do bones protect?
They protect vital organs and the central nervous system, which are soft and easily damaged.
During sport ……. is crucial for both …….. and ………. ……… ……. It reduces the chance of ………, which ensures players can continue to ……… and ……..
During sport protection is crucial for both performance and long term health. It reduces the chance of injury, which ensures players can continue to train and play.
when do you need protection of vital organs in sport?
E.g a Rugby Player’s Cranium (skull) will protect their brain during a scrum
muscle attachment plays an important part in?
hockey, deltoids attach to scapula so that you can dribble
mineral storage plays an important part in?
cycling, if you fall over and fracture your femur it will heal becuse of calcium
joints for movemnt plays and important part in?
rowing, A rower needs the bones in her arms (Humerus, Radius & Ulna) to join at her elbow creating the movement needed to pull an oar.
protection of vital organs plays an important part in?
rugby , protecting players cranium during a scrum
blood cell production plays an important part in?
rugby, platlets help the blood to clot so that a scab form and you can keep playing.
what are the classifictaion of bones?
flat, long, short, irregular
what are the flat bones of the skeleton?
cranuim, pelvis, clavicle, ribs, sternum
what are the long bones of the skeleton?
phalanges, femur, radius, ulna
