Superior pharyngeal constrictor muscle
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.

|Anatomical terms of muscle
The muscle is divided into four parts: A pterygopharyngeal, buccopharyngeal, mylopharyngeal 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 (Mylopharyngeal part)
- and by a few fibers from the side of the tongue (Glossopharyngeal part)
- Occipital bone seen from outside
- Inner surface of the Mandible seen from the side. The insertion of the mylopharyngeal part of the superior pharyngeal constrictor muscle is marked as "sup const".
