SINCLAIR, WILLIAM J. Initiation of rejlex swallowing from the nasoand oropharynx. Am. J. Physiol. 218(4) : 956-960. 1970.~In 15 electrolytically decerebrated cats, the pharynx was exposed surgically from the ventral aspect and divided in the midline. The pharynx was mechanically stimulated with light pressure using a wooden applicator 4 mm in diameter. Swallowing was noted visually and later ve...

Basal encephalocele is a rare craniofacial anomaly. In the present paper we report a 10-year-old boy presented with cleft palate, congenital nystagmus, and hypertelorism. During preoperative evaluation for cleft palate repair, a pulsatile mass was detected in the pharynx. Magnetic resonance imaging showed sphenoethmoidal type of basal encephalocele and agenesis of corpus callosum. Neurosurgical...

1. Activity in all three known conducting systems (the nerve net, SS1, and SS2) may accompany feeding in Calliactis. The most marked response is an increase in pulse frequency in the SS2 (the endodermal slow conducting system) during mouth opening and pharynx protrusion. 2. Electrical stimulation of the SS2 at a frequency of one shock every 5 s elicits mouth opening and pharynx protrusion in th...

During the development of the embryo, a process of cephalocaudal and lateral folding takes place with the result that part of the endoderm-lined cavity of the secondary or definitive yolk sac is incorporated into the embryo to form the primitive gut. In the cephalic part of the embryo, the primitive gut forms a blind ending tube, the foregut, separated from the ectodermally lined stomatodaeum b...

In this study an attempt was made to determine the position of the outlets and nuclei of the pharyngeal glands in four monhysterid genera. Five Eumonhystera spp., seven Monhystera spp., and eight Monhystrella spp. were studied under the light microscope. Longitudinal sections of an undescribed Monhystera sp. and cross sections of Geomonhystera disjuncta were also studied under the scanning and ...

We have compared ease of insertion, oropharyngeal leak pressure, directly measured pharyngeal mucosal pressure and anatomical position (assessed fibreoptically) for the size 4 and size 5 laryngeal mask airway (LMA) in 20 male and 20 female patients. Microchip pressure sensors were attached to the LMA at locations corresponding to the piriform fossa, hypopharynx, base of the tongue, lateral and ...

BACKGROUND Fungal colonization and infections remain a major cause of infection morbidity and mortality following hematopoietic stem cell transplantation (HSCT) in patients with hematological malignancies. The aim of this study was to analyze the spectrum of fungal microflora of the respiratory tract (oral cavity, pharynx, epiglottis, and sputum) in patients undergoing HSCT and to evaluate the ...

Progressive decline in mitochondrial function is generally considered one of the hallmarks of aging. We have expressed a Ca2+ sensor in the mitochondrial matrix of C. elegans pharynx cells and we have measured for the first time mitochondrial [Ca2+] ([Ca2+]M) dynamics in the pharynx of live C. elegans worms during aging. Our results show that worms stimulated with serotonin display a pharynx [C...
