Document Summary

* the larynx is also really important for phonation because of some of the folds and in particular the inferior fold which is the true vocal cords. * pic below shows the lateral view of the larynx with the anterior part on the right side and the posterior part to the left side. * at the very top is the hyoid bone which is the bone right at the root of the neck the crease between the floor of the oral cavity and the neck. So, males and females have a different quality of voice, largely because of the difference that the thyroid cartilage imparts on the vocal ligaments. * the thyroid cartilage has an angle anteriorly, has a big projection laterally and it is deficient posteriorly. * below the thyroid cartilage is the cricoid cartilage a(cid:374)d that"s the o(cid:374)e that sits dire(cid:272)tl(cid:455) o(cid:374) top of the trachea.
