Valleculae pouch-like openings at base of tongue and epiglottis. Piriform sinuses (recesses) two depressions along either side. Clivus density is same as cervical spine. Between hyoid bone and entrance to larynx and esophagus. Basilar portion of the skull and sphenoid bone create the slope: divert food away from larynx and into esophagus, sites to lodge foreign objects within the pharynx. 9 cartilages bony skeleton to protect the vocal cord. Three cartilages are unpaired: thyroid, epiglottis, cricoid. Posterior portion is much thicker than ant. Marks junction between the larynx and trachea, beginning of esophagus.
