Subscapular fossa
The subscapular fossa (of the scapula) is a structural feature on the scapula bone (also known as the shoulder blade or shoulder bone).
The subscapular fossa of the scapula bone is:
- the concave depression("fossa" = "shallow depression")
- located on the anterior = costal surface of the scapula bone only
Hence it isn't labelled on diagrams of the posterior = dorsal surface of the scapula.
The subscapular fossa extends over a large area of the costal surface of the scapula bone (as shown in the diagrams).
Several ridges extend from the medial border of the scapula into the smoother lateral area of the subscapular fossa.
Different areas, including the ridges, within the subscapular fossa form points of attachment of several muscles including the subscapularis and the serratus magnus.
