What is the origin of Salpingopharyngeus muscle?
Salpingopharyngeus muscle
| Origin | Inferior/cartilaginous part of auditory (Eustachian) tube |
|---|---|
| Insertion | Blends with palatopharyngeus muscle |
| Action | Elevates pharynx, opens auditory tube during swallowing |
| Innervation | Branches of pharyngeal plexus (CN X) |
Where is the salpingopharyngeus?
The salpingopharyngeus is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx. The paired slender muscles create vertical ridges of mucous membrane in the posterior pharyngeal wall descending from the medial ends of the Eustachian tubes to the called the salpingopharyngeal folds.
What does the Salpingopharyngeus muscle do?
Function. The salpingopharyngeus muscle raises the pharynx and larynx during deglutition (swallowing) and laterally draws the pharyngeal walls up. Unusually, it is relaxed during deglutition, but contracts at all other times.
How do you pronounce salpingopharyngeus?
Pronunciation
- (Classical) IPA: /sal.pin.ɡo.pʰaˈryn.ɡe.us/, [s̠äɫ̪pɪŋɡɔpʰäˈrʏŋɡeʊs̠]
- (Ecclesiastical) IPA: /sal.pin.ɡo.faˈrin.d͡ʒe.us/, [sälpiŋɡofäˈrin̠ʲd͡ʒeus]
Why stylopharyngeus is supplied by glossopharyngeal nerve?
The stylopharyngeus is a muscle in the head that stretches between the temporal styloid process and the pharynx….
| Stylopharyngeus muscle | |
|---|---|
| Origin | Styloid process (temporal) |
| Insertion | thyroid cartilage (larynx) |
| Nerve | glossopharyngeal nerve (CN IX) |
| Actions | elevate the larynx, elevate the pharynx, swallowing |
Is stylopharyngeus skeletal muscle?
The glossopharyngeal nerve provides motor innervation to the stylopharyngeus muscle. This cranial nerve has mostly sensory fibers, but provides motor innervation to one skeletal muscle, the stylopharygeus muscle.
What does Salpingopharyngeal mean in medical terms?
Definition of salpingopharyngeal : of or relating to the eustachian tubes and pharynx.
Is the pharynx?
The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea (the tubes going down to the stomach and the lungs)….

What is Passavants Ridge?
A. Flexible fiberscopic transnasal view of the nasopharynx showing the roof of the soft palate at the bottom of the view. The bulge of posterior pharyngeal wall that meets the soft palate is called Passavant’s ridge.
What is the salpingopharyngeus?
The salpingopharyngeus is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx . The paired slender muscles create vertical ridges of mucous membrane in the posterior pharyngeal wall descending from the medial ends of the Eustachian tubes to the called the salpingopharyngeal folds.
Where is the salpingopharyngeus muscle located?
The salpingopharyngeus is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx. The paired slender muscles create vertical ridges of mucous membrane in the posterior pharyngeal wall descending from the medial ends of the Eustachian tubes to the called the salpingopharyngeal folds. Summary. References.
How is the salpingopharyngeus supplied by the vagus nerve?
It passes downward and blends with the posterior fasciculus of the palatopharyngeus muscle. The salpingopharyngeus is supplied by the vagus nerve (CN X) via the pharyngeal plexus. The salpingopharyngeus muscle is supplied by the ascending pharyngeal artery .
Why does the salpingopharyngeus open the Eustachian tubes?
In addition, it opens the pharyngeal orifice of the pharyngotympanic tube during swallowing. This allows for the equalization of pressure between the auditory canal and the pharynx. As the salpingopharyngeus is used to open the eustachian tubes to equalize pressure in the middle ear, the muscle can easily be stimulated by swallowing.
