A

The 4th section of the vertebrae with 5 bones fused

28
Q

Are the coccyx bones fused

A

Yes

29
Q

What are the 5 sections of the vertebrae called

A

Cervical,Thoraic,Lumbar,Sacrum,Coccyx

30
Q

What are the 4 types of bones

A

Long bones,short bones,flat bones,irregular bones

31
Q

What do long bones do

A

They are vital to Generate movement,strength and speed.(levers/strength).They generate power and so are useful in activities such as sprinting and long jump

32
Q

What do short bones do

A

Weight bearing activities,shock absorption and spreading loads.such as long distance running,playing tennis or dancing

33
Q

What do irregular bones do

A

Protect/generate movement

34
Q

What do flat bones do

A

Protect vital organs/muscle attachments.For example the scapula has 3 muscles attached to it and the ribs protect the heart

35
Q

What are long bones classified as

A

Bones that are longer than they are wide it also has a shaft and two ends

36
Q

What are short bones classified as

A

They are generally the same in size,length and thickness they can be found in the carpals and the tarsals

37
Q

What do flat bones help in sport

A

They protect your organs in contact sport and also provide attachment for muscles to provide movement

38
Q

What are irregular bones classified as

A

They have very odd shapes and vary in function.For example the vertebrae which helps protect the spinal cord

39
Q

How do irregular bones help in sport

A

They offer protection for contact sports like rugby and have very specific functions such as the second and first vertebrae which allow the head to turn and nod.This helps us in football to head the ball

52
Q

What does a pivot joint do

A

Allow bones to rotate,one bone shaped like a cylinder rotates inside another bone or ligament that makes a ring around it

53
Q

What is an example of a pivot joint

A

The first two vertabrae form a pivot

A

Knee,ankle,elbow

56
Q

What is a ball and socket joint

A

57
Q

What is an example of a ball and socket joint

A

The hip,shoulder

58
Q

What is a condyloid joint

A

A joint that is similar to a ball and socket but the ball rests against the end of the bone not inside it.This allows for circular motion
