Pharyngobasilar Fascia
As it descends it diminishes in thickness, and is gradually lost. It is strengthened posteriorly by a strong fibrous band, which is attached above to the pharyngeal spine on the under surface of the basilar portion of the occipital bone, and passes downward, forming a median raphé, which gives attachment to the Constrictores pharyngis 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 (involunta .... Additional images File:Slide1kuku.JPG, Larynx, pharynx and tongue.Deep dissection, posterior view.

Pharyngeal Spine
The pharyngeal tubercle is a part of the occipital bone of the head and neck. It is located on the lower surface of the basilar part of occipital bone. It is the site of attachment of the pharyngeal raphe. Structure The pharyngeal tubercle is located on the lower surface of the basilar part of occipital bone. This about 1 cm anterior to the foramen magnum. Function The pharyngeal tubercle gives attachment to the fibrous raphe of the pharynx, also known as the pharyngeal raphe. This connects with the superior pharyngeal constrictor muscle. See also * Clivus (anatomy) The clivus (, Latin for "slope"), or Blumenbach clivus, is a bony part of the cranium at the base of the skull. It is a shallow depression behind the dorsum sellae of the sphenoid bone. It slopes gradually to the anterior part of the basilar occi ...

Pharyngeal Raphe
The pharyngeal raphe is a raphe that serves as the origin and insertion for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). Two sides of the pharyngeal wall are joined posteriorly in the midline by the raphe. Superiorly, it attaches to the pharyngeal tubercle The pharyngeal tubercle is a part of the occipital bone of the head and neck. It is located on the lower surface of the basilar part of occipital bone. It is the site of attachment of the pharyngeal raphe. Structure The pharyngeal tubercle is l ...; inferiorly, it extends to the level of vertebra C6 where it blends with the posterior wall of the esophagus.

Constrictores Pharyngis
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. There are two muscular layers of the pharynx: the outer circular layer and the inner longitudinal layer. The outer circular layer includes: * Superior constrictor muscle * Middle constrictor muscle * Inferior constrictor muscle During swallowing, these muscles constrict to propel a bolus downwards (an involuntary process). The inner longitudinal layer includes: * Stylopharyngeus muscle * Salpingopharyngeus muscle * Palatopharyngeus muscle During swallowing, these muscles act to shorten and widen the pharynx. They are innervated by the pharyngeal branch of the vagus nerve (CN X) with the exception of the stylopharyngeus muscle which is innervated by the glossopharyngeal nerve The glossopha ...

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it ...
