|Superior thyroid artery
|Depresses thyroid cartilage
|Anatomical terms of muscle
The two muscles are in contact with each other proximally (close their origin), but diverge distally (towards their insertions).
Clinical significance edit
The upward extension of a thyroid swelling (goitre) is prevented by the attachment of the sternothyroid to the thyroid cartilage. A goitre can therefore only grow to the front, back or middle but no higher.
