In this video, Ms. Windell Gaye C. Juntilla, a 4-DVM student, talks about the anatomy and physiology of the mammary gland. She gives an introduction of the salient features of the mammary glands of domestic animals and some species differences and important structures.

Anatomy of mammary gland
The development of the mammary gland starts early in fetal life. Already in the second month of gestation teat formation starts and the development continues up to the sixth month of gestation. When the calf fetus is six months, the udder is almost fully developed with four separate glands and a medial ligament, teat, and gland cisterns.

The development of milk ducts and the milk-secreting tissue take place between puberty and parturition. The udder continues to increase in cell size and cell numbers throughout the first five lactations of the cow, and the milk production capacity increases correspondingly.

To begin studying the anatomy of the mammary gland, some anatomical landmarks in the inguinal region must be identified; including the teats, four mammary quarters (two fore and two rear), mammary groove, and fore and rear quarter attachments (suspensory system).

A strong udder suspensory system is required to maintain proper attachments of the gland to the body. The mammary gland is a skin gland and is external to the body cavity. A Holstein cow may have 50 kg of weight hanging from her body when she walks into the milking parlor to be milked. So the system of ligaments and other tissues which attach the udder to the cow are critical for successful lactation.
