What is the calf bone called?
The outer leg bone is called the fibula. Gray's Anatomy (1918) describes it as the slender, non-weight-bearing bone of the leg, lateral to the tibia.
What it is
- The slender, non-weight-bearing bone of the leg, lateral to the tibia.
- Serves mainly as an attachment for muscles of the leg.
- Its lower end forms the outer ankle bone (lateral malleolus).
Where it is
- On the outer side of the leg, parallel to the tibia.
- Attached to the tibia above and below by strong ligaments.
- Its lower end can be felt as the bump on the outside of the ankle.
