nipple
Let an agent explain the nipple and its anatomy and function, relay variation and conditions in general terms from clinical sources, describe breastfeeding relevance, and route personal concerns 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 nipple and its anatomy and function, relay variation and conditions in general terms from clinical sources, describe breastfeeding relevance, and route personal concerns to clinicians.
The raised projection at the centre of the breast in mammals, surrounded by the areola, through which milk is delivered from the mammary ducts during lactation in females, present in both sexes as left and right nipples, and containing smooth muscle and dense sensory innervation; nipples vary in shape and can be affected by conditions such as inverted nipples, discharge, infection and Paget disease, and they are a focus of breast health awareness and of cultural norms about the body.
What it is for: Delivering milk and sensation.
It can be explain anatomy and function; relay variation and conditions; describe breastfeeding relevance; route personal concerns.
Distinguishing features
Milk duct outlet
Present in both sexes
Rich innervation
Variable form
What it looks like
A small raised projection at the centre of the areola on the breast.
Physical character
milk duct openings: about 4-18 count - per nipple
supernumerary nipples prevalence: about 1-5 percent
How it is recognised
Central projection of the breast
Male and female nipples, left and right; inverted nipples; supernumerary nipples
The areola surrounds it; the teat is the equivalent in other mammals; the breast is the whole organ

- How should clinical guidelines be linked?
- The registry entry has merged aliases naming sides and sexes; should they be split off?
