nail in dogs

A horn-like keratin structure covering the dorsal aspect of the terminal phalanges of fingers and toes[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the nail is

A horn-like keratin structure covering the dorsal aspect of the terminal phalanges of fingers and toes[WP]. The atlas records it as a organ at the organ scale in the dog.

Where the nail 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 nail connects to

The atlas records 17 typed relationships for it, across 6 kinds of connection. part of digit, integumental system and limb segment, and 3 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the nail. 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 nail/claw, claw and talon. Searching any of those names reaches this page.

Questions

Where is the nail?

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 nail connect to?

Part of: digit, integumental system, limb segment, multicellular organism, organ and skin epidermis.

Is the nail 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.
