sebaceous gland
Let an agent explain the sebaceous gland, relay its structure, secretion and role from anatomy and physiology sources, describe its named specialised forms, and distinguish it from sweat glands and other skin structures.
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 sebaceous gland, relay its structure, secretion and role from anatomy and physiology sources, describe its named specialised forms, and distinguish it from sweat glands and other skin structures.
A microscopic exocrine gland in the skin of mammals that secretes an oily or waxy substance called sebum to lubricate and waterproof the skin and hair; most are attached to hair follicles, and specialised forms the registry aliases name include the meibomian glands and glands of Zeis of the eyelid and the sebaceous glands of the areola and nipple. Sebaceous glands are holocrine, meaning the cells that produce sebum disintegrate to release it, and they are involved in conditions such as acne.
What it is for: Secreting sebum to lubricate skin and hair.
It can be explain structure and secretion; relay its role in skin and hair; describe specialised forms; distinguish it from sweat glands.
Distinguishing features
Secretes sebum
Holocrine mechanism
Attached to hair follicles
Present in mammalian skin
What it looks like
A tiny grape-like cluster of secretory cells, usually opening into a hair follicle, visible only under magnification.
Physical character
secretion: sebum note - oily or waxy
mechanism: holocrine note
registry parents: gland in skin, particular anatomical entity note
How it is recognised
Small gland opening into a hair follicle
Meibomian glands, glands of Zeis, areolar and nipple sebaceous glands
Sweat glands secrete watery sweat; sebaceous glands secrete oily sebum
