What level does the pharynx extend to
C6
What is the space between the pharynx and vertebral column
Retropharyngeal space
What structures joins the two sides of the pharynx posteriorly
Pharyngeal raph
Where does the upper part of the pharynx attach to the skull
Medial plate of pterygoid process, cartilaginous part of eustachian tube, pharyngeal tubercle of occiput
What is the superior constrictor attached to superiorly
The pterygomandibular raphe
Where does the middle constrictor attach to
Stylohyoid ligament
Where does the lower constrictor attach
Oblique line of the thyroid cartilage
Name the longitudinal muscles of the pharynx
Stylopharyngeus, salpingopharyngeus, palatopharyngeus
Above C6 what is the prevertebral fascia called
Buccopharyngeal fascia
Where do the lymphatics of the pharynx sit
Retropharyngeal space
What is the fascia that lies between inner layers of constrictors and mucosa called
Pharyngobasilar fascia
What fascia is continuous with pretracheal fascia
Buccopharyngeal fascia
Where do longitudinal muscles lie
Between mucosa and constrictors or between constrictors
What is the opening to the trachea called
Laryngeal inlet
What is the gap between the superior and middle constrictors and posterior border of mylohypoid called
The oropharyngeal triangle
What runs in the oropharyngeal triangle
Stylopharyngeus, styloglossus and hypoglossus C9, C12, lingual artery and lingual vein
What runs between the middle and inferior constrictors
Internal laryngeal nerve and vessels
