The Eight Functions of the Skeletal System

Question 1

what are the seven functions of the skeletal system

Answer 1

• supporting framework
• protection
• attachment for skeletal muscles
• blood cell production
• storage of minerals
• leverage
• weight bearing

Question 2

explain supporting of framework

Answer 2

• soft tissues are supported

- body shape is genetically determined by skeleton

Question 3

explain protection

Answer 3

flat bones protect vital organs

Question 4

explain attachment for skeletal muscle

Answer 4

• origins and insertions

- tendons attach muscle to bone

Question 5

explain blood cell production

Answer 5

• red and white blood cells are produced within long bones’ medullary cavity

Question 6

explain storage of minerals

Answer 6

• storage of calcium & phosphorus

- minerals mostly stored in long bones

Question 7

explain leverage

Answer 7

• mostly in appendicular skeleton

- movement by muscles pulling on tendons

Question 8

explain weight bearing

Answer 8

• short bones’ function is weight bearing

- strength to carry bone + muscle mass

Question 9

explain reduction of friction at a joint

Answer 9

• synovial fluid in a joint capsule
• cartilage on epiphyses
• sesamoid bones
