Histochemical patterns in the proventriculus of the developing chick
Journal of Morphology, 1967AbstractThe proventriculus of White Leghorn chick embryos (stages 29–45) newly‐hatched chicks, and adult chickens were frozen, sectioned in a cryostat and treated histochemically to identify localizations of alkaline and acid phosphatase, adenosine triphosphatase, 5‐nucleotidase, nucleotide‐diphosphatase, non‐specific glycerophosphatase, glucose‐6 ...

The proventriculus of the worker honeybee and its differentiation
Proceedings, annual meeting, Electron Microscopy Society of America, 1990The proventriculus (pv) of the honeybee regulates the flow of food from the crop into the midgut. It is a formation of the foregut intervening between the crop and the midgut and consists of four bulging pv folds forming a x-shaped lumen. At their ends (=lips) the folds bear filiform hairs forming a comb at their inner margins.

The proventriculus of some trichopterous larvae
Journal of Zoology, 1967A well‐developed proventriculus is present in larvae of the Polycentropodidae and Hydropsychidae. Its structure varies greatly between species but there is a common bilaterally symmetrical pattern based on a pair of posterior ventral folds. These are continuous with the sides of a ventral gap in the fold of foregut that invaginates into the midgut ...

The anatomy, physiology, and diseases of the avian proventriculus and ventriculus
Veterinary Clinics of North America: Exotic Animal Practice, 2003Diseases affecting the proventriculus and ventriculus often present with similar clinical signs. It is important for the avian practitioner to be familiar with these diseases, their prevalence, and the species most commonly affected to judiciously prioritize the appropriate diagnostic techniques.

The endocrine cells of the chicken proventriculus.
Basic and applied histochemistry, 1983The endocrine cells of the chicken proventriculus were investigated by selective staining techniques, immunohistochemistry and electron microscopy. The following endocrine cell types were identified: 1) Argyrophilic ECL-cells, of unknown function, were very numerous in the 21-day-old chick, but less numerous in the newborn chick; 2) somatostatin ...

Oxidative enzyme histochemistry of the chick esophagus and proventriculus
Journal of Morphology, 1968AbstractSuccinic dehydrogenase, NAD and NADP diaphorases, choline oxidase, d‐amino acid oxidase, α‐glycerophosphate dehydrogenase, glutamic dehydrogenase, lactic dehydrogenase and aldolase were identified histochemically in the esophagus and proventriculus of the developing chick embryo.

The Nervous System of the Chicken Proventriculus: An Immunocytochemical and Ultrastructural Study
The Histochemical Journal, 2000The proventriculus constitutes the glandular region of the chicken stomach. This organ is innervated by two parasympathetic networks, the myenteric and submucous plexus, and here we present a systematic study of this system by immunohistochemistry and electron microscopy.

Immunocytochemical and ultrastructural characterization of endocrine cells in chicken proventriculus
Cell and Tissue Research, 1991The endocrine cells of the chicken proventriculus were investigated immunocytochemically, using the peroxidase-antiperoxidase technique on paraffin and semithin sections for light microscopy, and immunogold staining in osmium-fixed material for electron microscopy. The fixation procedure also allowed a detailed ultrastructural investigation.

Postosmication of submucosal gland cells in the fowl proventriculus
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1963The technique of postosmication has been applied to resting and histamine-stimulated cells in the submucosal glands of the fowl proventriculus. In resting cells, the smooth endoplasmic reticulum, the mitochondria, and occasional vacuole-containing bodies become impregnated, but the Golgi apparatus, or ‘Dalton complex’ remains unaffected.
