8) Reduction friction across a joint

41
Q

What are the 3 types of joints?

A
  • Fixed
  • Slightly moveable
  • Synovial
42
Q

How are fixed joints formed?

A

When bones interlock during early childhood

43
Q

What is an example of a fixed joint?

A

44
Q

What are slightly moveable joints known as?

A

Cartilaginous

45
Q

What are the ends of slightly moveable joints covered with?

47
Q

Are synovial joints able to move?

A

Yes

48
Q

What does a ligament do?

A

Attach bone to bone

49
Q

What does a tendon do?

64
Q

What is lateral flexion?

A

Movement of bending sideways from the waist

65
Q

What is horizontal flexion?

A

With a straight arm or leg, moving that limb in front of your body

66
Q

What is horizontal extension?

A

Moving the limb away from the front of the body

67
Q

What is hyperextension?

A

Movement beyond the normal anatomical position, in the opposite direction to flexion

68
Q

What is circumduction?

A

A circular movement that results in a conical action

69
Q

What are the 2 responses of the skeletal system?

A
  • Production of synovial fluid
  • Increase in mineral uptake
70
Q

What does synovial fluid help with?

A

Making the joint more lubricated

71
Q

What happens to the synovial fluid during exercise?

A

It becomes less viscous and the range of movement increases

72
Q

What does the synovial fluid provide?

A

Nutrients for the articular cartilage

73
Q

What happens to your bones the more they are used?

A

They become stronger and denser

74
Q

What happens to our bones when we perform weight bearing activities?

A

The body absorbs minerals such as calcium to increase bone mineral density

75
Q

What is the adaptation of the skeletal system?

A

Increase in ligament strength

76
Q

What happens to ligaments over time?

A

They become more pliable to increase flexibility and range of movement

77
Q

What are the 3 additional factors of the skeletal system?

A
  • Arthritis
  • Osteoporosis
  • Age
78
Q

What is arthritis?

A

An inflammation to a synovial joint

79
Q

What is the most common type of arthritis?

A

Osteoarthritis

80
Q

How is arthritis caused?

A

Through the reduction of cartilage around the bone

81
Q

How does exercise prevent arthritis?

A

Our joints produce more synovial fluid to reduce friction and provide the cartilage with more minerals

82
Q

What is osteoporosis?

A

The weakening of bones due to a loss in calcium or a lack of vitamin D

83
Q

What happens to our bones as we get older?

A

They lose mineral density and become fragile and brittle

84
Q

How does exercise prevent osteoporosis?

A

It increases the uptake of minerals to increase bone mineral density

85
Q

What type of training shouldn’t be done at a young age?

A

Resistance/weight training
