Male mice lack nipples because the mammary tissue regresses in males during embryonic development. The single pair of mammary glands in humans is situated within the superficial facia of the anterior thoracic wall above the pectoralis major and extending upwards into the axilla. However, supernumerary...
The mammary glands are modified and highly specialized sweat glands. The whole system of mammary ducts is included in the context of an adipose mesenchyme that exerts considerable influence on its growth and evolution (Giordano et al., 2014). These influences are the result of a complex ...
This chromosomal region has not been implicated before in genetic disorders of the mammary tissue or limbs. These data suggest a possibly novel signaling pathway affecting the organogenesis of limbs and mammary glands in humans. European Journal of Human Genetics (2010) 18, 662–667; doi:10.1038/...
Mammary glands are milk-producing glands which are functional in nursing offspring. “Mammary” came from the Latin word “mamma” which translates to “breast." Normally, humans have two complex mammary glands where lactation occurs. These glands are regulated by the endocrine system. The major ...
The female breast in humans contain mammary glands that produce milk for nursing their young. The latin name for the breast is mamma, thus it is clear why we belong to the class of mammals together with many other animal species. If you begin to analyze the etymology of the word ‘mom...
In addition, the mammary epithelial tree of the alcohol-exposed offspring was denser (<0.004) and contained more structures that are susceptible for the initiation of breast cancer (<0.001). Immunohistochemical assessment indicated that the mammary glands of 22-week-oldalcohol-exposed rats contained ...

In rodents, the assessment of drug-induced changes in the mammary glands is complicated by species differences in hormonal regulation of mammary gland development and function, perhaps compounded by the artificial physiological state of overfed laboratory animals. The development and function of the ...
The chapter studies the anatomy of the endocrine system and the non-neoplastic changes associated with mammary glands. A mammary gland is a sensitive indicator of the functional activity of the hypothalamic-pituitary-gonadal axis, and its histological assessment provides important information about the ...
