Laryngopharnx
What is the opening of the mouth going to the pharynx
Oropharyngeal isthmus
What is the direct access to the nasal cavity
Choanae
Posterior nasal aperture
What is an opening that communicates with your Laryngopharnx
Laryngeal inlet
Which opens to the lateral wall of the nasopharynx
Eustachian tube
Which muscles attaches to the pterygoid process of the mandible
Superior constrictor muscle
What is the potential space for infection or gunshot wound
Retropharyngeal space
What are constrictor muscles seen at the pharyngeal wall
Circular muscles
The orientation of this muscle is vertical and oblique
Longitudinal muscle
Action of circular muscles
Pushes the food down

Elongate
Shorten
This muscle prevents back flow from the esophagus to pharynx

Pharyngeal raphe
What is the innervation of the stylopharyngeus muscle
Glossopharyngeal nerve
Which pharyngeal fascia is still part of the pre tracheal layer
Bucopharyngeal fascia
Where does the tensor and levator veli palatini crosses and comes in contact with pharyngeal muscles
Pharyngeal fascia
Important structure that closes and opens the pharynx
Soft palate
Epiglottis
What do you call the protection of the pharyngotympanic tube
Torus tubarius
What do you call the depression on each side of the glossoepiglottic fold

Piriform fosse
Where does the blood supply of the upper part of the pharynx come from
Branches from the external carotid artery
