Origin and Insertion
The four parts of this muscle arise from:
- the lower third of the posterior margin of the medial pterygoid plate and its hamulus (Pterygopharyngeal part)
- from the pterygomandibular raphe (Buccopharyngeal part)
- from the alveolar process of the mandible above the posterior end of the mylohyoid line (Myolopharyngeal part)
- and by a few fibers from the side of the tongue (Glossopharyngeal part)
The fibers curve backward to be inserted into the median raphe, being also prolonged by means of an aponeurosis to the pharyngeal spine on the basilar part of the occipital bone.
The superior fibers arch beneath the levator veli palatini muscle and the Eustachian tube.

Famous quotes containing the word origin:
“Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.”
—Oscar Wilde (1854–1900)
