Morphology and Development of the Rat Mammary Gland

Abstract

The mammary gland is an organ whose description in either morphology, physiology, or biochemistry requires one to specify the species, sex, age, reproductive history, and physiologic condition of the host before any definitive conclusion can be drawn. These variables pose a great burden on researchers in the field, since the massive literature available in some species might not apply to others, and extrapolations become necessary, though speculative and subject to further corroboration.
