Figure III
The intrinsic muscles of the larynx are nine in number, as follows:
2 Thyro-arytenoids, right and left.
2 Crico-thyroids, right and left.
2 Lateral crico-arytenoids, right and left.
2 Posterior crico-arytenoids, right and left.
1 Arytenoideus.
In Figure III these muscles are plainly shown. This cut presents a view of the interior of the left half of the larynx; the right half of the thyroid cartilage has been removed, together with the muscles which lie to the right of the middle line of the larynx. We see the muscles of the left side of the interior of the larynx and also the right posterior crico-arytenoideus and the right crico-thyroid.
