Neck Swelling: What to Know About Thyroid and Adam's Apple

Neck issues

When a physician feels two structures in the neck that move up and down during swallowing, the upper one is likely the Adam's apple (thyroid cartilage), and the lower one is probably the cricoid cartilage, which has a ring-like shape.
These two structures are typically separated by about one to two fingerbreadths.

More Info

When it comes to understanding neck swelling, particularly in the context of the thyroid and the Adam's apple, it's important to recognize the anatomy and function of these structures. The thyroid gland is located in the front of the neck and is responsible for producing hormones that regulate metabolism, growth, and development. The Adam's apple, or laryngeal prominence, is a feature of the larynx (voice box) and is more prominent in males due to the influence of testosterone during puberty. In females, the Adam's apple is typically less pronounced.

From your description, it sounds like you are feeling two distinct structures in your neck that move when you swallow. The upper structure you refer to as the "Adam's apple" is likely the thyroid cartilage, which forms the laryngeal prominence. The lower structure that feels like a ring is likely the cricoid cartilage, which is located just below the thyroid cartilage and forms a complete ring around the trachea (windpipe).
When you swallow, the larynx elevates, and this movement can be felt as the thyroid cartilage and cricoid cartilage shift. This is a normal anatomical feature, and the distance you describe between the two structures is also typical.
However, if you are experiencing any discomfort, swelling, or changes in swallowing, it is essential to consult a healthcare professional. Conditions affecting the thyroid, such as goiter (enlargement of the thyroid gland), thyroid nodules, or even thyroiditis (inflammation of the thyroid), can lead to noticeable changes in the neck area. Additionally, if there are any concerns about the movement of these structures or if you notice any unusual lumps or swelling, further evaluation may be warranted.

In summary, the structures you are feeling are likely normal anatomical features of your neck. The thyroid cartilage (Adam's apple) and cricoid cartilage are both part of the laryngeal framework and are involved in the swallowing process. If you have any concerns about your symptoms or the appearance of your neck, it is advisable to seek a thorough examination from an ENT specialist or a healthcare provider who can assess your condition and provide appropriate guidance. Regular check-ups and monitoring of thyroid function can also help in identifying any potential issues early on.
