This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients.
The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]

The posterior cricoarytenoid muscles are the only muscles to open the vocal cords. [1] [6] By abducting the vocal folds, the muscle opens the rima glottidis. [7]: 9 This is important in breathing and speech. [6] The muscles participate in the production of unvoiced vocal sounds. [1]
