Three nematodes : Amidostomum  acutum , Epomidiostomum uncinatum and Hadjelia truncata , were recovered from the gizzards of wintering mallard collected at two sites in central Iraq. A brief description of the parasites along with some notes on their infection rate, prevalence and discussion with the pertinent literature are provided.

Abstract The present study aimed to investigate the morphological description and histological structure of thyroid gland in Herpestes javanicus . The results revealed that thyroid gland in adult Herpestes javanicus is located in the neck region just below the larynx and attached to the trachea . Histological study revealed that thyroid gland in H. javanicus surrounded by a capsule of losse connective tissue and the thyroid gland mainly formed from follicles within different sizes. The results showed that the follicle consists of three compenets represented by follicular lining cells, basal parafollicular cells and the colloid. Microscopical examination revealed that the follicular lining tissue is either to be simple squamous or simple cub

The present study showed that the branchial arch is characterized by the presence of
irregular black line along its length. This line is condensations of melanocytes . The branchial
arch bears two rows of gill rakers at its anterior (internal) side whereas its posterior (external)
side bears two rows of gill filaments. Histologically, the gill arch is composed of hyaline
cartilage surrounded by mixed bone ,which is covered by a mucous membrane. Its epithelium
contains mucous cells and taste buds, whereas its loose connective tissue contains blood
vessels and skeletal muscles. The histological structure of gill raker is similar to that of the
gill arch except the absence of cartilage and muscles .The present st

Back ground; Selective re-absorption and secretion are the functions of the collecting tubules and ducts, in addition to concentrate urine through ADH-regulated and ADH-independent water channels.Method; twenty four male rats were used, they were divided into two groups of animals: Group (A) included twelve rats of five weeks old age (before puberty) that were divided into three subgroups, four rats in each subgroup. Subgroup I was control one, subgroups II and III were treated orally with melatonin in a dose of 250 & 500 µg/kg body weights subsequently. Group (B) included twelve rats of seventeen weeks old age (after puberty) that were divided into the same subgroups and treated with the doses of melatonin as in the rats of group (

The present study aimed to investigate the morphological and histological structure of pancreas in the bat,(Pipistrellus kuhlii). Pancreas was represented by compact pancreatic tissue which is divided into three parts : head , body and tail, its color is whit to yellow. The pancreatic tissue is located in the abdominal cavity near to the mass of intestine in the mesenteric network , which is connected with the coiled region of the duodenum in one side and with the extended mesenteries between the dorsal part of stomach and the abdominal part of spleen from the other side. The pancreas gland is surrounded by a loose connective tissue, the trabeculae are extended from it and divided the gland into many lobules which are different in shape

The aim of this study to investigate the tongue morphology and histology in house gecko Hemidactylus flaviviridis using light and scanning electron –microscopy (SEM ) technique.The morphology result revealed the presence of three parts : apex , body and lingual root .The light microscopy result showed that the tongue is covered with mucous membrane composed of non keratinized stratified squamous epithelium based on lamina propria which contain bundles of striated muscles its fibers in different directions including connective tissue , blood vessels and nerves. The lingual mucosa of the dorsal surface is covered with different pattern of lingual papillae which are widely distributed all over the dorsal surface except the apex. Noticed on t
