Microanatomy and histological study of the Salt Glands of the territorial lovebirds (Agapornis taranta)

The present study was conducted to determine the anatomical and histological structure of the salt glands in territorial lovebirds (Agapornis taranta).In this study used (15) adult birds, which divided in tow groups, the first group contains (5) birds used for anatomical study includes positon, shape, segmentation, weight and width.The second group includes (10) other birds used for histological study. Two types of stains were used. This study revealed that the lovebirds owns a pair of salt glands, It is well advanced located (left and right), anatomically the salt glands of lovebirds are situated in the supra orbital grooves of the frontal bones and covered by thine connective tissue membrane. The salt glands appear as crescent shape or narrow oval shape with anterior pointed part and posterior broad part. The mean weight (0.25 ) gm. Its mean length gland (2.8 mm and the mean width are   (0.26 ) mm.       Histological examination revealed that the functional unit of the salt gland in form of secretory lobule which is represented a tubular structure that radiate around a central canal that drain in a mine duct which is lined by stratified cuboidal epithelium and leads to collecting duct that leads to anterior of the  nasal cavity

Histomorphological study of the liver in local Moorhen birds (Gallinula chloropus).

The present study was performed to illustration some anatomical and histological characteristics of the liver of adult male moorhen bird Gallinula chloropus. The present study was conducted on 20 birds divided into two groups (10 for anatomical study and 10 for histological study) mature male healthy moorhen bird were used.The liver of moorhen bird Gallinula chloropus was located in the right, left hepatoperitoneal cavity, seems red-brown in color. Moreover, divided into two lobes, right and left, the left lobe appear larger than right lobe. Histologically the liver of moorhen bird enclosed by thin capsule of connective tissue. The hepatocytes, which arranged radially around the central vein as hepatic cords in two cells thickness. These cells are polygonal in shape and have rounded nucleus and present of sinusoids between hepatic cords which lined by flattened endothelial cells
