strand of hair

A filament, mostly protein, that grows from follicles found in the dermis[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the strand of hair is

A filament, mostly protein, that grows from follicles found in the dermis[WP]. The atlas records it as a organ at the organ scale in the human body.

Where the strand of hair 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 strand of hair connects to

The atlas records 24 typed relationships for it, across 6 kinds of connection. part of pilosebaceous unit and skin epidermis.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the strand of hair. 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 hair, coat hair, coat/ hair, fur, microchaeta and quill, and 3 more. Searching any of those names reaches this page.

Questions

Where is the strand of hair?

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 strand of hair connect to?

Part of: pilosebaceous unit and skin epidermis.

Is the strand of hair 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.
