Pectoralis minor fascia


This is the fascia which covers the pectoralis minor and invests it anteriorly and posteriorly. It begins at its attachment with the axillary fascia at the base of axilla and then runs upwards to reach the outer border of the pectoralis minor where it spilts into a duality to invest the muscle. It gathers again at the inner border of the pectoralis minor to become the clavipectoral fascia.
