No, the vocal cord is not a cartilage.
The reference states that the vocal cords are folds of fibro-elastic tissue. They attach anteriorly to the thyroid cartilage and posteriorly to the arytenoid cartilage. This indicates that the vocal cords themselves are a different type of tissue (fibro-elastic) from cartilage, but connect to cartilages.
Here's a table to illustrate the relationship:
| Structure | Tissue Type | Relationship to Vocal Cords |
|---|---|---|
| Vocal Cords | Fibro-elastic | Main vibrating structure |
| Thyroid Cartilage | Cartilage | Anterior attachment point |
| Arytenoid Cartilage | Cartilage | Posterior attachment point |
