'''* Mamma (pleural=Mammae) ''': the glandular structure associated with a teat
** '''Lobes''': the internal compartments of the mamma, separated by adipose tissue. The lobes are divided into '''lobules'''. Lobules consist of connective tissue containing '''alveoli''', which are clusters of milk secreting cells.
** '''Lactiferous Ducts''': large ducts conveying milk from the alveoli to the milk sinus. The openings of lactiferous ducts convey milk formed in the alveolus to the gland sinus.
* Milk/Lactiferous Sinus: milk storage cavity within the teat and glandular body.
** Gland Sinus: part of the milk sinus within the glandular body.
** Teat Sinus: part of the milk sinus within the teat.
* Teat: projecting part of the mammary gland containing part of the milk sinus.
** Teat Canal: canal leading from the teat sinus to the teat opening.
** Teat Opening: opening of the teat canal. The exit point for milk or entrance point for bacteria into the mammae.
* Sphincter: muscular fibres surrounding the teat opening that prevent milk flow except during suckling or milking.
