The anterior wall of the pharynx is deficient and replaced by the _____
posterior opening into the nose (choanae)
opening into the mouth,
and inlet of the larynx
Muscles of the pharynx with fibers that run in a more or less circular direction.
Superior, middle and inferior constrictors
Muscles in the wall fibers run in a more or less longitudinal direction.
stylopharyngeus
salpingopharyngeus muscles
The lower part of the inferior constrictor, which arises from the cricoid cartilage, is called the _________.
cricopharyngeus muscle
O: medial pterygoid late; pterygoid hamulus, pterygomandibular ligament; mylohyoid line of mandible
I: pharyngeal tubercle of occipital bone, raphe in midline posteriorly
NS: pharyngeal plexus
A: aids soft palate in closing off nasal pharynx, propels bolus downward
Superior constrictor
O: lower part of stylohyoid ligament; lesser and greater cornu of hyoid bone
I: pharyngeal raphe
NS: pharyngeal plexus
A: propels bolus downward
Middle constrictor
O: lamina of thyroid cartilage; cricoid cartilage
I: pharyngeal raphe
NS: pharyngeal plexus
A: propels bolus downward
Inferior constrictor
O: lower fibers of inferior constrictor muscle
I:
NS:
A: sphincter at lower end of pharynx
Cricopharyngeus
O: styloid process of temporal bone
I: posterior border of thyroid cartilage
NS: glossopharyngeal nerve
A: elevates larynx during swallowing
Stylopharyngeus
O: auditory tube
I: blends with palatopharyngeus
NS: pharyngeal plexus
A: elevates pharynx
Salpingopharyngeus
O: palatine aponeurosis
I: post border of thyroid cartilage
NS: pharyngeal plexus
A: elevates wall of pharynx, pulls palatopharyngeal folds medially
Palatopharyngeus
lies above the soft palate and behind the nasal cavities
Nasal pharynx
collection of lymphoid tissue in the roof
Pharyngeal tonsil
opening in the floor between the soft palate and posterior pharyngeal wall
Pharyngeal isthmus
opens on the lateral wall of the nasal pharynx
Auditory tube
elevated edge of the auditory tube
Tubal elevation
depression in the pharyngeal wall behind the tubal elevation
Pharyngeal recess
vertical fold of mucous membrane covering the salpingopharyngeus muscle
Salpingopharyngeal fold
Parts of the nasal pharynx
Pharyngeal tonsil Pharyngeal isthmus Auditory tube Tubal elevation Pharyngeal recess Salpingopharyngeal fold
lies behind the oral cavity
Oral pharynx
Parts of the Oral pharynx
Medial glossoepiglottic fold Lateral glossoepiglottic fold Vallecula Palatine tonsils Tonsillar sinus Oropharyngeal isthmus
found in the midline of the floor between the tongue and epiglottis
medial glossoepiglottic fold
Found on each side of the oral pharynx
lateral glossoepiglottic fold
