Clavipectoral fascia – surround subclavius/pectoralis minor
1. Costocoracoid membrane – upper segment (named for med/lat attachments) * pierced by 3 structures: - Cephalic v. - Thoracoacromial a. - Lateral Pectoral n.
2. Suspensory Ligament of Axilla – lower segment – fuses with axillary fascia at axillary floor
