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.
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.
Pharyngeal muscles or Branchial muscles are striated muscles of the head and neck. Unlike skeletal muscles that developmentally come from somites, pharyngeal muscles are developmentally formed from the pharyngeal arches. Most of the skeletal musculature supplied by the cranial nerves (special visceral efferent) is pharyngeal.
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]
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 ...
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 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 salpingopharyngeus muscle is a muscle of the pharynx. It arises from the lower part of the cartilage of the Eustachian tube, [1] and inserts into the palatopharyngeus muscle by blending with its posterior fasciculus. It is innervated by vagus nerve (cranial nerve X) via the pharyngeal plexus.
