fascial plane
What type of tissue is the pharynx
musculo-membranous tissue
What are the muscles of the pharynx

What is the origin of the superior constrictor
medial pterygoid plate, mandible, hamulus,
What is the action of the superior constrictor muscle
elevate and constrict pharynx
What is the origin of the middle constrictor
hyoid cornua and stylohyoid ligament
What is the action of the middle constrictor
constrict pharynx
What is the origin of the inferior constrictor
thryroid and cricoid cartilages
What is the action of the inferior constrictor
constrict the pharynx
What is the innervation for the superior, middle,and inferior constrictors, as well as palatopharyngeal, and salpingopharyngeal mm
CN10– pharyngeal branch

median raphe
What is the origin of the stylopharyngeus
styloid process of temporal bone
What is the action of the stylopharyngeus
elevates pharynx
What is the insertion of the stylopharyngeus
blends with pharyngeal tissues
