Mystus ngasep, a new catfish species (Teleostei: Bagridae) from the headwaters of Chindwin drainage in Manipur, India. It feeds on plankton and decayed vegetables. Secretin affects the enzyme-carrying juices from the pancreas and accelerates the flow of zymogens. This is because the hormones secreted by these glands directly through the help of different biochemical reactions and reveals various characteristics, as well as play a role in controlling the secretion of other endocrine glands. Classification kingdom Animalia phylum . In bony fish it is located along the arterial artery, in cartilage fish along the midline of the tongue muscle. This hormone is synthesized from the anterior region of the small intestine. Various studies have shown that two types of gonadotropes are found in fish which are known as FSH and LH in mammals. External nares lie on the dorsal surface of the snout. One of the two alpha cells secretes the hormone A1 glucagon.

It is the largest of all islets. The islets in Channa punctatus are located near the spleen and pylorus. It contains acidophils, cyanophils and chromophobes. Lateral line system is well developed. The secretion of interenal tissue is regulated by adrenocorticotropic hormones of the pituitary gland. In Mystus aor, it resembles sagitate, in Bagarius bagarius it resembles a rosette or rose, in Wallago attu it is angular and in Nangra punctata it is funnel-shaped.

The site is secure. simply extremely magnificent. It is located esophageal ventral wall between esophagus and sinus venous, Located on the dorsal side along the kidney. Gonadotropes (FSH and LH cells): These cells are usually present in meso-adenohypophysis, but sometimes, especially during the sexual maturity of eel (Olivereau 1967) and trout (Baker 1968), these cells enter pro-adenohypophysis. The endocrine system mainly controls the relatively slow metabolism of carbohydrates and water through the adrenal cortical tissue, the metabolism of nitrogen through the adrenal cortical tissue and thyroid gland, and the maturation and sexual behavior of germ cells through the pituitary and sex hormones. This gland secretes two peptide hormones, urotensin-1 and urotensin-2. Final Report of the R&D-Projekt 808 05 081.

Adenohypophysis):It is divided into three types: These are: Pro-adenohypophysist: It covers most of the frontal lobes of adenohypophysis. Head contains mouth, snout, eyes and barbels. In most teleosts, the thyroid gland is composed of numerous follicles surrounding the arterial artery and the afferent bronchial blood vessel. The fish were treated to the sub-lethal concentration viz. [1] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.[2]. Hormones are secreted from the endocrine glands and transported to certain parts of the body to exert a specific physiological effect there. Talwar, P.K.

Found in rivers, canals, beels, ditches, inundated fields and other freshwater areas. The endocrine gland is unanimously referred to as the ductless gland whose secretory substance is released directly into the blood or lymph. It is a fresh water fish and shows sexual dimorphism. It is thought that this hormone also plays a role in regulating secretion. This fish contains 4 pairs of barbels and above features, hence it is Mystus seenghala. . Fertilization is generally external. Moreover, estrogen controls the sexual behavior of the female fish. It is found in clear and sluggish rivers and streams.

Some aerial fish such as Channa punctatus, C. gachua, C. marulius, C. striatus and Heteroneustes fossilis have a dense and covered thyroid gland near the aortic artery (Belsare 1959). It does not store any personal data. and transmitted securely. The extracellular mass contains a significant number of pancreatic islets of various shapes. In fish (Heteropneustes, Clarias, Channa) hyperglycemia occurs when glucose is applied and hypoglycemia occurs when insulin is applied, resulting in degradation of beta cells. x=rG?#0!4p8gHk O)0a 53pzg|s~?_,..]\>Wvpik9Z}m7Ol|"+Segw//Q*3-3,3X^o?W2~C^Y4b/Y:~ & These follicles vary in size and shape and are joined by connective tissue.
