- The thyroid rests just below the Adam's apple (or where the Adam's apple would be on a female) and is next to the trachea and larynx.
Two Frontal Lobes
- The thyroid has two lobes--left and right--that wrap around the trachea.
- Isthmus is a small bit of tissue connecting the right and left lobes of the thyroid gland. This connection is what gives the thyroid the butterfly shape it is known for.
- A tough, fibrous block of tissue covers the thyroid gland, completely encasing it and protecting it from other tissues and organs in the body.
Superior Thyroid Artery
- The superior thyroid artery, part of the external carotid artery, feeds blood to the thyroid.
