| mammary duct ectasia | A noncancerous breast disease most often found in women during menopause. The ducts in or beneath the nipple become clogged with cellular and fatty debris. The duct may have gray to greenish discharge, a lump you can feel and can become inflamed, causing pain. (09 Oct 1997) |
| mammary ducts | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi. (05 Mar 2000) |
| mammary dysplasia | An obsolete term for fibrocystic condition of the breast. (05 Mar 2000) |
| mammary fistula | A fistulous opening into one of the lactiferous ducts. Synonym: mammary fistula. (05 Mar 2000) |
| mammary fold | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |
| mammary gland | <anatomy> Milk producing gland of female mammals. An adapted sweat gland, it is made up of milk producing alveolar cells, surrounded by contractile myoepithelial cells, together with considerable numbers of fat cells. Milk production is hormonally controlled. (18 Nov 1997) |
| mammary line | A transverse line drawn between the two nipples. (05 Mar 2000) |
| mammary neoplasms | Tumours of the mammary gland. Their occurrence is uncommon with the exception of the female dog, in which they account for 25% of all neoplasms. (12 Dec 1998) |
| mammary neuralgia | Neuralgia of the intercostal nerve or nerves supplying the breast. (05 Mar 2000) |
| mammary plexus | A lymphatic plexus, including the parasternal; (internal thoracic) lymph nodes, with their vessels, situated along the course of the internal thoracic veins. Synonym: mammary plexus, plexus mammarius. (05 Mar 2000) |
| mammary region | The region of the breast. Synonym: regio mammaria. (05 Mar 2000) |
| mammary ridge | Bandlike thickening of ectoderm in the embryo extending on either side from just below the axilla to the inguinal region; in human embryos, the mammary glands arise from primordia in the thoracic part of the ridge, the balance of the ridge disappearing; in some lower mammals which give birth to a litter of young, several milk glands develop along these lines. Synonym: mammary fold, milk line, milk ridge. (05 Mar 2000) |
| mammary souffle | A blowing murmur heard late in pregnancy and during lactation at the medial border of the breast, sometimes only systolic and sometimes continuous. (05 Mar 2000) |
| mammary tumour virus | <organism, virology> Retrovirus that induces mammary carcinoma in mice. Isolated from highly inbred strains that had very high incidence of the tumours, after the discovery that the disease was transmitted by nursing mothers in milk. Endogenous provirus present in germ line of all inbred mice. Transcription of the provirus is regulated by a viral promoter that increases transcription in response to glucocorticoid hormones. May transform by proviral insertion activating the cellular int 1 oncogene (18 Nov 1997) |
