Answer:
The ankle joint includes the articulation of the ti bia, fib ula, ta lus, and calca neus. Option (5) is true.
Step-by-step explanation:
The medial malleo lus is formed by the fi bula:
This is incorrect.
The me dial malleolus is formed by the ti bia, not the fibul a.
The lateral malle olus is formed by the fib ula.
It is not stable in plant arflexion:
This is incorrect.
The ankle joint is more stable in plantarflexion (pointing the foot downward) due to the engagement of bony structures.
It is a syno vial plane joint:
This is incorrect.
The ankle joint is a hin ge joint, allowing primarily dors iflexion (lifting the foot upward) and planta rflexion.
It allows inversion and eversion:
This is correct.
Inversion (turning the sole of the foot inward) and eversion (turning the sole of the foot outward) are movements possible at the ankle joint.
It includes articulation of tibia, fibula, talus, and calcaneus:
This is correct.
The ankle joint involves the articulation of the tibia and fibula (lower leg bones) with the talus (foot bone) and indirectly with the calc aneus (heel bone).
Thus, option (5) is true.
