thyrohyoid muscle

The thyrohyoid muscle is a small, quadrilateral muscle appearing like an upward continuation of the Sternothyreoideus. It belongs to the infrahyoid muscles group. It arises from the oblique line on the lamina of the thyroid cartilage, and is inserted into the lower border of the greater cornu of the hyoid bone. [WP,unvetted].

Questions

Where is the thyrohyoid muscle?

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

What does the thyrohyoid muscle connect to?

A kind of: infrahyoid muscle.

Is the thyrohyoid muscle 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.
