mammary gland
Let an agent explain the mammary gland across mammals in clinical and biological terms, relay its structure, development and function, describe its roles in human health and in dairy animals, and route personal health questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the mammary gland across mammals in clinical and biological terms, relay its structure, development and function, describe its roles in human health and in dairy animals, and route personal health questions to clinicians.
The exocrine gland in mammals that produces milk to feed the young, a defining feature of the class, present in both sexes but developing fully in females, and consisting of lobes of secretory tissue drained by ducts to a nipple or teat; mammary glands range from the human breast to the udder of cattle and other livestock, are controlled by hormones through pregnancy and lactation, and are the site of breast cancer and of dairy production.
What it is for: Producing milk for the young.
It can be explain structure and development; explain lactation and its control; describe human and veterinary relevance; route personal questions to clinicians.
Distinguishing features
Defines mammals
Modified skin gland
Hormonal control
Sexual dimorphism in development
What it looks like
Glandular tissue within the breast or udder, with ducts opening at nipples or teats; visible externally as breasts or udders.
Physical character
lobes per human breast: about 15-20 count
teats in cattle: 4 count - one udder
How it is recognised
Milk-producing exocrine gland
Present in all mammals, both sexes
Sweat glands are related evolutionarily but distinct; the breast is the whole region including fat

What the second pass must settle

- How should clinical and veterinary standards be linked?
- The registry entry has merged an alias for an unrelated ear structure; should it be removed?
