What is the shape of the arytenoid cartilages?

The arytenoid cartilages are correctly described as pyramid-shaped structures located in the larynx. Their pyramid form allows for a wide range of movement, which is essential for the regulation of vocal folds during phonation. Each arytenoid cartilage has a base and an apex, which contribute to its triangular configuration. This unique shape facilitates their role in opening and closing the vocal cords, as well as enabling adjustments to tension and position for sound modulation. Such movement is crucial for producing a variety of pitches and tones in speech and singing. The anatomical design of the arytenoid cartilages plays a significant role in the intricate mechanics of voice production, making their pyramidal shape essential for the function they serve in the vocal apparatus.
