Fibula

This tutorial explores the fibula, a slender long bone in the lower leg, highlighting its anatomical features, functions, and articulations. The fibula supports the ankle and provides muscle attachment sites. Key features include the proximal head, shaft, and distal lateral malleolus. The fibula articulates with the tibia at the superior and inferior tibiofibular joints. Various muscles, such as the biceps femoris and soleus, attach to the fibula, contributing to its role in movement and stability.
