hypodermis in dogs

Lowermost layer of the integumentary system in vertebrates. Types of cells that are found in the hypodermis are fibroblasts, adipose cells, and macrophages. It is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm. The hypodermis is used mainly for fat storage[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the hypodermis is

Lowermost layer of the integumentary system in vertebrates. Types of cells that are found in the hypodermis are fibroblasts, adipose cells, and macrophages. It is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm. The hypodermis is used mainly for fat storage[WP]. The atlas records it as a tissue at the tissue scale in the dog.

Where the hypodermis is

It sits within the integumentary system. Only the system is known. The position shown carries almost no spatial information.

What the hypodermis connects to

The atlas records 13 typed relationships for it, across 6 kinds of connection. part of integument, integumental system and organ.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the hypodermis. 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

Questions

Where is the hypodermis?

It sits within the integumentary system. Only the system is known. The position shown carries almost no spatial information.

What does the hypodermis connect to?

Part of: integument, integumental system and organ.

Is the hypodermis 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.
