Consider generalizing to deuterostome pharynx

Swollen region of the anterior foregut, posterior to the mouth and anterior to the liver; its walls form the jaws and gills. Kimmel et al, 1995.[TAO], Swollen region of the anterior foregut, posterior to the mouth and anterior to the liver; its walls form the jaws and gills[ZFA:0000056, ZFIN:ZDB-PUB-961014-576]., The portion of the alimentary canal between the mouth and the oesophagus. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG], A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNYX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx)[MESH:A03.867]., Anatomical cavity bounded by the derivatives of the branchial arches.[AAO]

MA/FMA pharynx not part of digestive/alimentary system, we are consistent with this scheme

pharynx

uberon

(...) the earliest vertebrates possessed unjointed internal and external branchial arches, and musculature encircling the pharynx.[well established][VHOG]
