Which cartilage is attached to the superior cornu of the hyoid bone?

The thyroid cartilage is indeed attached to the superior cornu of the hyoid bone. This connection is significant because the hyoid bone serves as an important anatomical structure that supports the tongue and provides attachment points for muscles associated with swallowing and speech.

The thyroid cartilage is the largest cartilage of the larynx and plays a crucial role in protecting the vocal folds and forming the front wall of the larynx. Its superior cornua extend upwards to meet the hyoid bone, creating a supportive relationship between these structures. This anatomy is vital for various functions, including resonance, phonation, and airway protection.

In contrast, the other cartilages mentioned do not have this attachment to the hyoid bone. The cricoid cartilage is located inferior to the thyroid cartilage and forms a complete ring around the airway, while the arytenoid cartilages are located posteriorly and are pivotal for vocal fold movement. The cuneiform cartilages are small structures that provide structural support within the larynx but do not connect to the hyoid bone. Understanding these anatomical relationships enriches knowledge of the laryngeal framework and its role in speech and swallowing.
