Structure[edit]
The stylopharyngeus is a long, slender muscle, cylindrical above, flattened below. It arises from the medial side of the base of the temporal styloid process, passes downward along the side of the pharynx between the superior pharyngeal constrictor and the middle pharyngeal constrictor, and spreads out beneath the mucous membrane.
Some of its fibers are lost in the constrictor muscles while others, joining the palatopharyngeus muscle, are inserted into the posterior border of the thyroid cartilage.
The glossopharyngeal nerve runs on the lateral side of this muscle, and crosses over it to reach the tongue.
Innervation[edit]
Stylopharyngeus is the only muscle in the pharynx innervated by the glossopharyngeal nerve (CN IX) and is done by its motor branch, which supplies special visceral efferent (SVE) fibers to it.
Actions[edit]
The stylopharyngeus:
- elevates the larynx
- elevates the pharynx
- dilates the pharynx to permit the passage of a large food bolus, thereby facilitating swallowing
Embryological origin[edit]
Third pharyngeal arch

- Measuring the effect of avermectins and milbemycins on somatic muscle contraction of adult Haemonchus contortus and on motility of Ostertagia circumcincta in vitro.
- Demeler J1, VON Samson-Himmelstjerna G1, Sangster NC2.Author information 1Institute for Parasitology and Tropical Veterinary Medicine, Freie Universität Berlin, Königsweg 67, 14163 Berlin, Germany.2Faculty of Veterinary Science, University of Sydney, 2006 NSW, Australia.AbstractSUMMARY The mechanism of anthelmintic resistance against the widely used macrocyclic lactones (MLs) is still not fully understood. Pharyngeal, somatic body muscles and the ovijector have been proposed as putative sites of action as well as resistance. In the present study the effects of three avermectins and three milbemycins on adult parasitic nematodes were evaluated in vitro. The Muscle Transducer system was used to investigate the effects of MLs on muscle contraction in female Haemonchus contortus and effects on motility were measured in Ostertagia (Teladorsagia) circumcincta using the Micromotility Meter. Concentration-response curves for all substances in both systems shifted to the right in the resistant isolates. Resistance was present to ivermectin (IVM) and its components IVM B1a and IVM B1b, suggesting that both components are involved in the mode of action and resistance. No consistent patterns of potency and resistance of the substances were observed except that milbemycins generally showed lower resistance ratios (RRs) than IVM. IVM and IVM B1b were the most potent inhibitors of contraction and motility in both susceptible isolates and also showed the highest RR in both species. Low RRs for milbemycins recorded in vitro for highly resistant isolates in vivo suggest that other factors such as pharmacokinetics influence drug potency in vivo.

- Gross anatomical observations of attachments of the middle pharyngeal constrictor.
- Sakamoto Y.Author information Basic Sciences of Oral Health Care, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.AbstractThe pharyngeal muscles overlap each other and some of their parts have different areas of origin. Such arrangements make the interrelationships among pharyngeal muscles complicated. This study investigated the attachments of the middle constrictor to clarify its configuration and re-examine its functions. The gross anatomies of the pharyngeal and neighboring muscles were examined in 41 cadavers. The middle constrictor arose from the stylohyoid ligament and the hyoid bone, and its fibers were divided into three overlapping groups. The anterosuperior group ascended posterosuperiorly from the ligament and the lesser horn and fanned out. The middle group ascended posterosuperiorly from the greater horn and fanned out. The posteroinferior group fanned out from the posterior part of the greater horn, while the middle constrictor arose internally to the hyoglossus; some fibers often passed externally, and their fibers sometimes intersected around the lingual artery, which ran between them. Some fibers attached to the hyoglossus, occasionally to the stylohyoid and the posterior belly of the digastric, but seldom to the lingual artery and the triticeal cartilage in the thyrohyoid ligament. The three groups were inserted into the pharyngeal raphe, and the descending fibers joined the longitudinal pharyngeal muscles. The ascending and descending fibers rarely reached the top of the pharynx and the thyroid cartilage, respectively. The fiber arrangement suggested that, besides constriction of the pharynx, the ascending and descending fibers of the middle constrictor can act as an elevator muscle, and the irregular attachments could affect the functions of the muscles and vessels.
