Infrahyoid (strap) muscles
Musculi infrahyoidei · Podjazylkové svaly
Muscles
Looks like
Four thin ribbons on each side of the front of the neck, below the hyoid bone.
What it does
Pull the voice box and hyoid down after swallowing, and steady them for speech.
Keeping it well
Nothing routine; a lump that moves up when you swallow is thyroid, not muscle.
