The mucous membrane has been removed from the piriform recesses and anterior wall of the esophagus. The right superior laryngeal nerve (22) has been retracted to expose branches of the superior laryngeal artery (20) and vein.

- Pharyngeal branch of external carotid artery
- Lateral thyrohyoid ligament (Triticeal cartilage not present)
- Superior laryngeal nerve
- Superior horn thyroid cartilage
- External carotid artery
- Corniculate tubercle
- Piriform recess (mucosa removed)
- Inferior pharyngeal constrictor muscle (cut across)
- Common carotid artery
- Thyroid gland
- Root of tongue
- Epiglottis
- Pharyngoepiglottic fold (mucosa preserved)
- Aryepiglottic fold (inner mucosal surface preserved)
