Document Summary

All the structures in the neck are found middle to anterior regions; all lie anterior the spine. Include the pharynx, larynx, esophagus, trachea, salivary glands, thyroid gland, & cervical lymph nodes. Attached to one another by connective tissues & muscles. Funnel shaped tube that acts as an opening for the resp & digestive system. Extends from the base of the skull & ends inferiorly at the continuation of the esophagus. Has a respiratory function to allow for the passage of air from the nasal cavity to larynx. Density is the same as the cervical spine; therefore know its bone. Created by the basilar portion of the occipital bone of the head, the sphenoid bone (the 2 bones create the slope) Inferior boundary: soft palate to level of uvula (projection on the posterior aspect of the soft palate) Lateral boundary: opening of the auditory tube that connects middle ear to nasopharynx; posterior to nasal conchae.
