Joints of the ankle
/dʒɔɪnts/ /ʌv/ /ðʌ/ /æŋkʌl/
1. [noun] the ankle joint is a synovial hinge joint that provides plantarflexion and dorsiflexion. The ankle joint is made up of distal ends of the tibia and fibula, which form a socket that fits over the top portion of the talus. The bones are held together by several ligaments.

Frequently Asked Questions
How do dorsiflexion and plantarflexion help in everyday movements involving the ankle?
Daily activities such as stepping off a curb or pushing off during a run rely on these motions. The ankle's hinge mechanism allows dorsiflexion (raising the foot) and plantarflexion (pointing the foot down), which are essential for smooth walking and balance.
In what way does the bone arrangement of the tibia, fibula, and talus support ankle function?
The tibia and fibula form a sturdy socket that cradles the talus, creating a hinge-like joint. This precise arrangement, reinforced by ligaments, is integral to managing the forces and movements encountered during everyday foot actions such as running or climbing stairs.
