The medial thyroid gland has the shape of a triangle, with its apex pointing downward, and its base adjacent to the spine.
Anterior to and above the medial thyroid gland is the aortic arch.
The esophagus is located between the medial thyroid gland and the aorta.
On the posterior surface of the medial thyroid gland is the pericardium.
Vessels, nerves and lymphatic vessels pass through the medial thyroid gland.
