Pharynx Flashcards
Where does the pharynx extend from?
Skull base to inferior border of cricoid cartilage
Border between the nasopharynx and oropharynx
Soft palate
What cervical level is the cricoid cartilage located?
C6
What are the borders of the oropharynx
Soft palate to epiglottis
What are the borders of the laryngopharynx?
Epiglottis to base of cricoid cartilage
Where is the eustachian tube located?
Posterior to inferior concha
Connection between the pharynx and middle ear
Eustachian tube
What is the torus tubarius?
Cartilage of the eustachian tube
The groove along the lateral pharyngeal wall
Pharyngeal recess
Where is the pharyngeal tonsil located?
Postero-superior to torus tubarius
What is the salpingopharyngeal fold?
Mucous membrane covering the salpingopharyngeus m.
What is the palatoglossal arch?
Mucosal fold over the palatoglossus m.
The mucosal fold over the palatopharyngeus m.
Palatopharyngeal arch
Where is the palatine tonsil located?
In tonsillar bed between 2 palatine arches
The palatopharyngeal sphincter is located where?
On deep surface of the superior constrictor
Where is the piriform recess?
Lateral to thyroid cartilage
Nerve of the laryngopharynx that descends beneath the mucous membrane
Internal laryngeal n.
What vessels run with the internal laryngeal n.?
Superior laryngeal
Nerve that passes by the thyroid gland and ascends beneath the mucous membrane
Recurrent laryngeal n.
What runs with the inferior laryngeal vessels?
Recurrent laryngeal n.
The constrictor muscles are innervated by this nerve
CN X
What innervates the stylopharyngeus m.?
CN IX
Where does the superior pharyngeal constrictor attach?
Pterygoid hamulus
Pterygomandibular raphe
Pharyngeal raphe
Where does the middle pharyngeal constrictor attach?
Stylohyoid ligament
Hyoid
Where does the inferior pharyngeal constrictor attach?
Thyroid cartilage
Cricoid cartilage
the inferior extent of the inferior constrictor m.
Cricopharyngeus m.
What nerve provides sensory innervation to the nasopharynx?
CN V2
What nerve provides sensory innervation to the oropharynx?
CN IX
What nerve provides sensory innervation to the laryngopharynx
CN X
Muscle that arises from the styloid process to the pharynx
Stylopharyngeus m.
The salpingopharyngeus muscle arises from here
Auditory tube
The salpingopharyngeus muscle blends with this muscle
Palatopharyngeus m.
Two muscles that arise from the soft palate and make up the tonsillar pillar
Palatopharyngeaus m.
Palatoglossus m.
The arterial supply of the pharynx is predominantly via these areteries
Ascending pharyngeal a
Superior thyroid a.
Innervation of the pharynx is via this
Pharyngeal plexus of nerves
This supplies sympathetic nn. to the pharyngeal plexus
Superior cervical ganglion
What supplies motor innervation too the pharyngeal plexus?
CN X
What supplies sensory innervation to the pharyngeal plexus?
CN IX
Loss of motor function to the pharynx causes this
Dysphagia
Loss of sensory function to the pharynx can cause this
Loss of gag reflex
Accidently swallowed objects may become trapped here
Piriform recess
Enlarges pharyngeal tonsils are called this
Adenoids
