head mesenchyme

Portion of primordial embryonic connective tissue of the developing head, consisting of mesenchymal cells supported in interlaminar jelly, that derive mostly from the mesoderm and contribute to head connective tissue, bone and musculature in conjunction with cranial neural crest cells. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the head mesenchyme is

Portion of primordial embryonic connective tissue of the developing head, consisting of mesenchymal cells supported in interlaminar jelly, that derive mostly from the mesoderm and contribute to head connective tissue, bone and musculature in conjunction with cranial neural crest cells. The atlas records it as a tissue at the tissue scale in the human body.

Where the head mesenchyme is

It sits in the head. 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 head mesenchyme connects to

The atlas records 12 typed relationships for it, across 4 kinds of connection. part of embryo, embryonic structure and head.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the head mesenchyme. 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 cephalic mesenchyme, cranial mesenchyme and desmocranium. Searching any of those names reaches this page.

Questions

Where is the head mesenchyme?

It sits in the head. 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 head mesenchyme connect to?

Part of: embryo, embryonic structure and head.

Is the head mesenchyme 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.
