Meckel's cartilage

Meckel's cartilage is the bilaterally paired, rod-like, cartilaginous ventral component of the lower jar, or ventral mandibular arch. It is typically resorbed in adults. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the Meckel's cartilage is

Meckel's cartilage is the bilaterally paired, rod-like, cartilaginous ventral component of the lower jar, or ventral mandibular arch. It is typically resorbed in adults. The atlas records it as a cartilage at the organ scale in the human body.

Where the Meckel's cartilage is

It sits in the head, within the skeletal and digestive systems. 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 Meckel's cartilage connects to

The atlas records 9 typed relationships for it, across 3 kinds of connection. part of axial skeletal system, digestive system and skeleton of lower jaw, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the Meckel's cartilage. 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 Meckels cartilage, cartilago arcus pharyngei primi, primary mandinle and ventral mandibular cartilage. Searching any of those names reaches this page.

Questions

Where is the Meckel's cartilage?

It sits in the head, within the skeletal and digestive systems. 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 Meckel's cartilage connect to?

Part of: axial skeletal system, digestive system, skeleton of lower jaw, splanchnocranium and subdivision of skeletal system.

Is the Meckel's cartilage 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.
