cricoid cartilage
A cartilaginous ring that provides support for the arytenoid cartilages and forms the caudal part of the larynx. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the cricoid cartilage is
A cartilaginous ring that provides support for the arytenoid cartilages and forms the caudal part of the larynx. The atlas records it as a cartilage at the organ scale in the human body.
Where the cricoid cartilage is
It sits within the skeletal and respiratory systems. Positioned deliberately as part of this species body plan.
What the cricoid cartilage connects to
The atlas records 15 typed relationships for it, across 5 kinds of connection. a kind of laryngeal cartilage.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the cricoid 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.

Questions
Where is the cricoid cartilage?
It sits within the skeletal and respiratory systems. Positioned deliberately as part of this species body plan.
What does the cricoid cartilage connect to?
A kind of: laryngeal cartilage.
Is the cricoid 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.
