Retropharyngeal space is bounded by
buccopharyngeal fascia anteriorly, prevertebral fascia posteriorly, and carotid sheaths laterally.
The pharyngeal gut is separated from the primitive oral cavity by the
buccopharyngeal membrane, whereas the foregut extends to the cloacal membrane that is the boundary between endoderm and ectoderm (1-9).
To the Editor: The parapharyngeal space is a potential neck space between prevertebral fascia and
buccopharyngeal fascia.
Posteriorly its attachment to
buccopharyngeal fascia in nasopharynx was dissected.
This slight elevation of the zygomatic musculature is commonly observed among major singing artists who adhere to the international school of resonance balancing." (2) Furthermore, Miller adheres to the old adage "inhale as though smelling the fragrance of a rose." (3) As such, he suggests, "Having the zygomatic muscles follow patterns associated with pleasant facial expression achieves an uncontrived adjustment of the entire
buccopharyngeal cavity." (4) Depending on the uniqueness in the physiology of the vocal tract of any given singer, slight movements of these muscles may produce different resonance balances from one singer to the next.
Taste is a subjective sensation and taste perceptions in aglossia patients have been documented to be intact.18 This can be attributed to the fact that taste buds are present not only on the tongue but also on the floor of mouth, epiglottis, soft palate and mucous membrane projection which is actually a remnant of embryonic
buccopharyngeal membrane.
Use of PRV as a neural tracer shows that, during the
buccopharyngeal phase of following, vagal afferents from the pharynx and larynx and fibers of the superior laryngeal nerve terminate in the intermediate and interstitial subnuclei of the NTS.
Thornwaldt's cyst is differentiated from Rathke's pouch (diverticulum of nasopharyngeal mucosa, a remnant of
buccopharyngeal membrane invagination to form anterior lobe of pituitary) by the presence of cylindrical ciliated columnar epithelium as compared to internal stratified squamous epithelium found in Rathke's pouch.
Males ventilate the burrows by filling their
buccopharyngeal cavity with air and expelling the air during forays into the burrows (Ishimatsu et al., 1998).
Among its components, the
buccopharyngeal cavity has attracted great attention among researchers, as it is intrinsically related to the selection, capture, directing and preparation of the food to be swallowed (LOURES; LIMA, 2001).
The uvula being the site of the primitive
buccopharyngeal membrane would therefore be derived from the same precursor?
The retropharyngeal space is a potential space that lies posterior to the
buccopharyngeal fascia, anterior to the prevertebral fascia of the cervical and thoracic spine and extends laterally to the carotid sheaths.
