Mobile
Pharynx attaches to what membrane
Pharyngobasilar membrane which is made of CT
Clivus formed from
Joining of occipital (posterior) and sphenoid (anterior) in relation to the esophagus
Nasopharynx limits
Nasal cavity to soft palate
Constrictor muscles are
Circular muscles –> move the bolus
Name the constrictor muscles
Superior constrictor
Middle constrictor
Inferior constrictor
Which constrictor muscle inserts into the stylohyoid ligament
Middle constrictor
Which constrictor muscle forms the fake sphincter between the pharynx and the esophagus
Inferior constrictor
Insertion of constrictor muscles
Pharyngeal raphe –> retropharyngeal spaces
Name the longitudinal muscles
Palatopharyngeous
Stylopharyngeous
Salpingopharyngeous
Nasopharynx closes due to
Elevation of soft palate
Muscles of the palate

Jugular foramen
Pharyngeal branches provided by
X vagus nerve
Pharyngeal plexus formed of
Pharyngeal branches of X vagus nerve
Nerves of IX glossopharyngeal nerve
Cervical sympathetic nerves
Glossopharyngeal nerve relationship with hyoglossus and stylopharangeous muscle
Anterior to stylopharyngeous muscle and then it goes deep to hyoglossus muscle

Venous drainage
To facial vein that drains into INTERNAL jugular vein
IX glossopharyngeal nerve gathers information from
Mucosa of oropharynx and posterior 1/3 of tongue
Pharynx
Body and carotid sinus
