Early Embryonic Development of the Harderian Gland of the Common Quail (coturnix Coturnix)
The present research aimed at giving a special focus on the early development of the Harderian gland – the principal orbital gland in birds. The development of the Harderian gland was studied in the common quail (Coturnix coturnix) at 7, 8, 9 and 10 days of incubation. The Harderian gland started its development as a long tube with a narrow lumen proximally and undifferentiated lumen distally a...
متن کاملScanning Electron Microscopic Studies of the Pecten Oculi in the Quail (Coturnix coturnix japonica)
The main purpose of this study is to extend the microscopic investigations of the pecten oculi in the quail in order to add some information on the unresolved functional anatomy of this unique avian organ. The pecten oculi of the quail was studied by scanning electron microscopy. Eighteen- to-twenty two highly vascularised accordion-like folds were joined apically by a heavily pigmented bridge ...
متن کاملA light and electron microscopic study of the limb long bones perichondral ossification in the quail embryo (Coturnix coturnix japonica).
The perichondral ossification of the limb long bones in the quail embryo is investigated, in this study, by means of light and electron microscopy. Longitudinal sections of the humerus, radius, ulna, femur, tibia and fibula stained with haematoxylin-eosin were examined by the light microscope. Ultrathin cross sections were selected for the electron microscope as well. Light microscopic analysis...
متن کاملUltrastructure of the parathyroid gland of the quail, Coturnix coturnix japonica.
Electron microscopic studies were made of the parathyroid gland of quail aged 4 to 12 months. Most parenchymal cells consisted of chief cells. Sometimes, cells having numerous microfilaments, scant granular endoplasmic reticulum, a few mitochondria, a small Golgi apparatus, and long cell processes that extended between contiguous cells were located on a basal lamina. These cells may serve as su...
متن کاملNutrient Benefits of Quail (Coturnix Coturnix Japonica) Eggs
Cross-sectional study of quail eggs was conducted to evaluate the nutritional compositions of carbohydrate, fat, protein, calories, vitamin, minerals and sex hormones. The results showed that average of each whole quail egg weight was 10.67 g. Their contents of ash, carbohydrate, fat, protein and moisture were 1.06, 4.01, 9.89, 12.7 and 72.25 g 100g -1 , respectively. Total energy in calories o...
