Skin: The skin is lax and contains Langerís lines running transversely. Suspensory ligaments (or ligaments of Astley Cooper; or ligaments of Cooper) of the breast run from the deep fascia, which covers the muscle to the skin.
fascia: This underlies the skin and covers the whole

Deep fascia: This is called
fascia and it covers the external surface of the pectoralis major.
pectoralis minor fascia begins at its junction with the
axillary fascia, which
forms the floor of the axilla. It runs upwards to reach the external border of
minor, where it splits into two to invest the external and internal
surfaces of that muscle. It then meets at its internal border to continue
upwards. It splits again to invest the
and finally gains attachment
to the undersurface of the clavicle at the
subclavian groove of that structure.
