The thyroid gland, located just below the Adam's apple, is approximately 5 cm (2 inches) long. A healthy thyroid gland typically does not protrude from the throat and is not visible in the neck region. However, various medical conditions can lead to the abnormal enlargement of the thyroid gland; this condition is known as 'goiter'.

In the presence of goiter, the following symptoms may be observed:

* A noticeable swelling in the front of the neck, just below the Adam's apple
* A feeling of tightness or fullness in the throat area
* Hoarseness or a husky voice
