Question 18

What are the five functions of the skeletal system

Answer 18

Protection of vital organs
Staying safe is important in sport and the skeleton play a key role. E.g. the skull protects the brain and the ribs protect the internal organs, including the heart.
• Muscle attachment
The muscles you use in sport need strong points to attach to and bones provide that framework.
Muscles are attached to bones by tendons.
• Joints for movement
Joints allow the body to make a variety of movements. Some are small movements, like getting a grip of a javelin and larger ones, such as throwing a javelin.
• Storing calcium and phosphorus
The bones act as a store for calcium and phosphorus, two minerals that are vital for developing and maintaining the strong and healthy bones you need for exercise. The best sources for both minerals are milk, cheese and yoghurt. Phosphorus helps to reduce muscle pain after exercise.
• Red and white blood cell production
When the oxygen content drops, or the number or red blood cells goes down, your bone marrow makes more red blood cells; if you have an infection, it makes more white blood cells.

Question 19

What are 4 types of bones

Answer 19

Long bones
Short bones
Irregular
Flat bones

Question 20

What is the function of long bones

Answer 20

Generate movement(leavers)/strength

Question 21

What is function of short bones?

Answer 21

Weight bearing

Question 22

What is the function of irregular bones

Answer 22

Protection / generate movement

Question 23

What is the function of a pivot joint?

Answer 23

Allow bones to rotate

Question 24

What is the function of a hinge joint?

Answer 24

A hinge joint is a joint that allows only backward and forward motion - just like the hinge on a door. There are three hinge joints: the knee, elbow and ankle.

Question 25

What is the function of a ball and socket joint?

Answer 25

helps in rotational or circular movements, as one bone is captivated into the hollow space of another bone

Question 26

What is the function of a condyloid joint ?

Answer 26

condyloid joint is similar to a ball and socket joint, but the ball rests against the end of a bone, rather than inside a socket. This allows circular motion.
