hyoid bone

A horseshoe shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. [WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the hyoid bone is

A horseshoe shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. [WP,modified]. The atlas records it as a bone at the organ scale in the human body.

Where the hyoid bone is

It sits within the skeletal system. Positioned deliberately as part of this species body plan.

What the hyoid bone connects to

The atlas records 18 typed relationships for it, across 7 kinds of connection. part of splanchnocranium and subdivision of skeleton.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the hyoid bone. 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 hyoid, hyoid bone, hyoideum, lingual bone and os hyoideum. Searching any of those names reaches this page.

Questions

Where is the hyoid bone?

It sits within the skeletal system. Positioned deliberately as part of this species body plan.

What does the hyoid bone connect to?

Part of: splanchnocranium and subdivision of skeleton.

Is the hyoid bone 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.
