d to the deep pectoral 3° THE BREAST fascia and the latter in turn to the periosteum of the sternum thus producing the inter-mammary sulcus. Deep Pectoral Fascia.—A deep layer of fascia is also found covering all parts of thesurface of the body and in general it immediately underlies the superficial fascia, but incertain areas, such as the cervical and pectoral regions, it forms inter-muscular septathat permit of its division into two or more planes. The deep pectoral fascia is composedof an anterior and a posterior layer. The anterior layer covers the superficial aspectof the great pectoral muscle. It is attached above to the clavicle, medially to the perios-teum of the sternum and is continuous below with the deep fascia covering the rectusabdominis and external oblique muscles, and laterally with that covering the serratusmagnus muscle below, and the deltoid muscle above. Between these muscles, the samefascia spans the base of the axilla, of which space it constitutes the floor.

Fig. 13.—Dissection to show the attachments of the stroma of the breast to the deep pectoral fasciaand to the superficial fascia with both of which it is continuous. As the anterior layer turns around the outer border of the pectoralis major to becomethe axillary fascia, it gives off a prolongation that separates the two pectoralmuscles. This splits to enclose the pectoralis minor muscle, at the upper inner margin ofwhich it again unites and is continued upward, as the costo-coracoid membrane, to theunder-surface of the clavicle, where it again divides to enclose the subclavius muscleand to be inserted into the lips of the subclavian groove. These layers are collectivelyknown as the posterior layer of the deep pectoral fascia or the clavi-pectoral fascia. Purulent collections between the pectoral muscles or behind the pectoralis majormuscle are directed to the anterior border of the axilla or to the upper end of the delto-pectoral groove by the clavi-pectoral fascia.
