hair follicle in dogs

A tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the hair follicle is

A tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open[GO]. The atlas records it as a organ at the organ scale in the dog.

Where the hair follicle is

It sits within the integumentary system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the hair follicle connects to

The atlas records 14 typed relationships for it, across 7 kinds of connection. part of organ, pilosebaceous unit and skin epidermis, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the hair follicle. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as folliculus pili. Searching any of those names reaches this page.

Questions

Where is the hair follicle?

It sits within the integumentary system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the hair follicle connect to?

Part of: organ, pilosebaceous unit, skin epidermis and zone of skin.

Is the hair follicle the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
