The center of the breast integument is characterized by the roundish, glabrous (hairless) musculocutaneous specialization, nipple-areola complex, enriched with the integumentary class of smooth muscle tissue, which bundles are intimately intermingled with fibro-elastic connective tissue of the reticular dermis, with the openings of the distal, ending parts of excretory mammary gland ductal system, situated at the tip of the nipple. Inside this specific breast skin complex composed of two anatomically recognizable regions, muscle tissue is continuous, extending through the areola and nipple, nevertheless, functioning as one anatomic unit. Although present in both genders, in female physiology during the reproductive part of life, it is significantly more developed, and beside sexual arousal reaction, the major function of this structure is transitory contractile activity as essential part of physiological mechanisms necessary for regulated milk releasing during the period of breastfeeding. Nevertheless, analyzed in details and well defined from 19th century, latter, the topic of the nipple-areola complex muscular system in usual textbooks of anatomy and histology conceived unjustifiably a prejudice of marginality. Understanding the necessity for didactical recapitulation and systematization of data about the musculature of the complex and its associated structures, we reviewed the available literature, especially sources which were important for the theme and less often noticed in contemporary reviews.

Centralna pozicija integumenta dojke se karakteriše prisustvom, kružne, glabrozne (bezdlake), muskulo-kutane specijalizacije, areolarno-mamilarnim kompleksom, specifičnim po prisustvu integumentarne klase glatkomišićnog tkiva, čiji su snopovi utkani u fibroelastično tkivo retikularnog derma, a otvori distalnih, završnih delova ekskretornog duktalnog sistema mlečne žlezde, smešteni u vršnom delu bradavice dojke. Unutar ovog specifičnog kompleksa kože dojke, sačinjenog od dva anatomski prepoznatljiva činioca, mišićno tkivo je kontinualnog prostiranja, i pruža se kroz areolu i bradavicu, funkcionišući kao jedinstvena anatomska jedinica. Iako prisutna kod osoba oba pola, u fiziologiji ženskog organizma, tokom reproduktivnog perioda života, značano biva razvijenija i pored uloge u reakcijama polnog uzbuđenja, glavna funkcija ove strukture je tranzitorna kontraktilna aktivnost, kao deo fiziološkog mehanizma kojim se obezbeđuje kontrolisano oslobađanje mleka tokom procesa dojenja. Još tokom istraživanja sprovedenih tokom devetnaestog veka, ova struktura je analizirana i definisana do detalja, ali je kasnije, u uobičajenim udžbenicima anatomije i histologije zapostavljena zbog predrasude o marginalnosti značaja. Shvatajući potrebu za didaktičkom rekapitulacijom i sistematizacijom podataka vezanih za muskulaturu i pridružene strukture ovog kompleksa, ovde je predstavljen pregled dostupne literature, naročito iz onih izvora, koji su bili od značaja za razvoj teme, ali su ređe bili predstavljani u savremenoj naučno-stručnoj publicistici.
