Q

What bones make up the leg?

A

Tibia and fibula

17
Q

What is an aponeurosis?

A

A tissue that connects flat sheet muscle to bone

18
Q

Where are tendons found?

A

Between bone and muscle

19
Q

What is the function of tendons?

A

They transfer force between muscle and bone to generate movement

20
Q

What is the function of ligaments?

A

To connect bone to bone

21
Q

What are characteristics of tendons and ligaments?

A

They are generally stiff, inelastic and stabilise joints by limiting movement

22
Q

What kind of joint is the elbow?

A

Synovial

23
Q

What range of movement is exhibited by the elbow?

A

Extension and flex ion

24
Q

Which ligaments restrict movement of the elbow joint?

A

The lateral and medial collateral ligaments

25
Q

Why is the knee joint unstable?

A

As the inferior of the femur and superior aspect of the tibia don’t fit well together

26
Q

Why are the ligamentum flavum different from other ligaments?

A

They have a high content of elastin fibres and so are more elastic than most ligaments

27
Q

What ligaments stabilise the knee?

A
  • Medial and lateral collateral ligaments
