👉 The term "retromammillary" is not commonly used or defined. It may be a misnomer, as it does not accurately describe the structure of the breast gland in humans. Retromammillary refers to the part of the breast that contains the ductus arteriosus, which is an important blood vessel for pumping blood from the heart into the breasts. To clarify this term, please provide more context or information about the specific structure you are referring to.
