Soleal line
Linea musculi solei
Definition
The soleal line is a diagonal bony ridge that is located in the upper portion of the posterior surface of tibia. It is oriented downward and medially.
Above the soleal line, the triangular region of the posterior surface of tibia serves as the point of origin for the popliteus muscle.
The soleal line gives rise to the soleus muscle and the fascial coverings of the soleus and popliteus muscles.
Below the soleal line, the posterior surface is divided into medial and lateral halves by a vertical bony ridge. The medial half gives rise to the flexor digitorum longus muscle, while the lateral half provides origin for the tibialis posterior muscle.
