Cooper's ligaments
Cooper's ligaments (also known as the suspensory ligaments of Cooper and the fibrocollagenous septa) are connective tissue in the breast that help maintain structural integrity. They are named for Astley Cooper, who first described them in 1840.〔A. P. Cooper. On the anatomy of the breast. 2 volumes. London, Longman,1840.〕 Their anatomy can be revealed using Transmission diffraction tomography.
Cooper's Suspensory Ligament should not be confused with the pectineal ligament (sometimes called the inguinal ligament of Cooper) which shares the same eponym. Also, the intermediate fibers and/or the transverse part of the ulnar collateral ligament are sometimes called Cooper's ligament(s).〔http://medical-dictionary.thefreedictionary.com/transverse+ligament+of+elbow〕〔Waldeyer's Human Anatomy - Membrum superius, articulatio cubiti〕
==Anatomy==
The ligaments run from the clavicle and the clavipectoral fascia branching out through and around breast tissue to the dermis of the skin overlying the breast. The intact ligament suspends the breast from the clavicle and the underlying deep fascia of the upper chest. This has the effect of supporting the breast in its normal position, and maintaining its normal shape. Without the internal support of this ligament, the breast tissue (which is heavier than the surrounding fat) sags under its own weight, losing its normal shape and contour.
