The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity. The pharyngeal muscles (involuntary skeletal) push food into the esophagus.
Its posterior border gives attachment to the superior pharyngeal constrictor muscle. [3] Its anterior border attaches to the posterior edge of the buccinator muscle. [3] The pterygomandibular raphe is the common meeting point of the superior pharyngeal constrictor muscle and the buccinator muscle. This common attachment makes the raphe a ...
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
Dissection of the muscles of the palate from behind. The five muscles of the soft palate play important roles in swallowing and breathing. The muscles are: Tensor veli palatini, which is involved in swallowing; Palatoglossus, involved in swallowing; Palatopharyngeus, involved in breathing; Levator veli palatini, involved in swallowing
The pharyngeal raphe is a raphe that serves as the posterior attachment for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). [1] [2] Two sides of the pharyngeal wall are joined posteriorly in the midline by ...
The buccopharyngeal fascia envelops the superior pharyngeal constrictor muscles. [4] [1] It extends anteriorly from the constrictor pharyngis superior [4] over the pterygomandibular raphe to cover the buccinator muscle [1] (though another source describes it as continuous with the fascia covering the buccinator muscle). [3]
The superior pharyngeal constrictor muscle is a quadrilateral muscle of the pharynx. It is the uppermost and thinnest of the three pharyngeal constrictors. [citation needed] The muscle is divided into four parts according to its four distincts origins: a pterygopharyngeal, buccopharyngeal, mylopharyngeal, and a glossopharyngeal part.
The levator veli palatini (/ l ɪ ˈ v eɪ t ər ˈ v iː l aɪ ˌ p æ l ə ˈ t aɪ n aɪ /) is a muscle of the soft palate and pharynx. It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus. During swallowing, it contracts, elevating the soft palate to help prevent food from entering the nasopharynx.
