The superior pharyngeal constrictor muscle is a muscle in the pharynx. It is the highest located muscle of the three pharyngeal constrictors. The muscle is a quadrilateral muscle, thinner and paler than the inferior pharyngeal constrictor muscle and middle pharyngeal constrictor muscle. The muscle can divided into four parts: A pterygopharyngeal, buccopharyngeal, myolopharyngeal and a glossopharyngeal part. == 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Superior pharyngeal constrictor muscle」の詳細全文を読む スポンサード リンク
