| Parents sustain themselves during incubation on energy stored as body fat and lipid-rich stomach oil in the proventriculus. |
|
| Four tunnels off the lumen of the proventriculus of the carpenter bee, Xylocopa virginica virginica, have been discovered. |
|
| Cut the heavy muscular wall of the gizzard with a knife and extend the incision up through the proventriculus and lower oesophagus to the crop. |
|
| The proventriculus of the worker honeybee is an organ which effects a highly efficient separation of pollen grains from the medium in which they are suspended. |
|
| Enhanced levels of expression are seen in older embryos adjacent to the segmental involutions and in the salivary glands, proventriculus, and somatic musculature. |
|
| The crop discharges into the midgut, sometimes, as in cockroaches, by way of a muscular gizzard or proventriculus. |
|
| The esophagus, proventriculus, and ventriculus were tied off from adjacent sections of the digestive tract to prevent mixing of contents. |
|
| The stomach is typically divided into a glandular proventriculus and a muscular gizzard, the latter lying near the centre of gravity of the bird and compensating for the lack of teeth and the generally weak jaw musculature. |
|
| Samples from brain, proventriculus, and ventriculus were embedded in paraffin wax, sectioned at 4 pm, and stained with hematoxylin and eosin. |
|
| Afterwards, the EP-procyclin remained the dominant surface protein during the different developmental stages in the midgut, proventriculus and foregut and the immature stages in the salivary glands. |
|
| A crop-support pressure bandage was placed in 4 birds to improve crop emptying into the proventriculus and to prevent crop distension. |
|
| The proventriculus, gizzard, pancreas, duodenum, jejunum and ileum were removed and weighed. |
|
| They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. |
|
| The proventriculus and ventriculus contained a small amount of mucus. |
|
| Besides the esophageal lymphoma, neoplastic lymphoid cells were observed in the adrenal glands, liver, kidneys, lung, proventriculus, and gizzard. |
|
| This oil is created in a stomach organ known as a proventriculus from digested prey items by most Procellariiformes, and gives them their distinctive musty smell. |
