hair follicle

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 human body.

Where the hair follicle is

It sits within the integumentary system. Positioned deliberately as part of this species body plan.

What the hair follicle connects to

The atlas records 11 typed relationships for it, across 6 kinds of connection. part of pilosebaceous unit, skin epidermis and zone of skin.

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. Positioned deliberately as part of this species body plan.

What does the hair follicle connect to?

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

Is the hair follicle the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
