The ADW Team gratefully acknowledges their support. However, as a result of hyperglycemia, beta cells are destroyed by taking beta-cytotoxic drugs such as aloxacin and streptozotocin. Other types of cells are stained with azacarmine or erythrosine (prolactin cells). 13. Although mammalian endocrinology is more advanced, but studies have been performed on hormone-regulating functions in fish. These islets may have distinct entities and may extend to the pancreatic lobe. First dorsal fin contain week and raised dorsal spine. From histological point of view, each stannius particle consists of parenchymal cells. These form singles or groups within the adrenal cells or form adrenal complexes jointly with the adrenal glands. A total of 60 fish of three different length groups (20 each) were collected from Head Qadirabad, Pakistan. Classification kingdom Animalia phylum .

Haematological and biochemical parameters and tissue accumulations of cadmium in Oreochromis niloticus exposed to various concentrations of cadmium chloride. These follicles vary in size and shape and are joined by connective tissue. We also earn by displaying ads by Google AdSense. Parathyroid hormone secreted from the anterior and posterior pituitary glands, insulin and glucagon are secreted from the pancreas, calcitonin is secreted from the ultimobronchial gland, relaxin hormones are secreted by the ovarian and hormones of other glands. In the caudal neurosecretory system, neurosecretory cells extend to the margins of the spinal cord. Urophysis is composed of components of the spinal cord such as neurosecretory axons, glia, glial fibers and meningeal derivatives such as tubular reticulum and reticular fibers. Gills are weakly developed. It lives in rivers and large lakes of tropical Africa.

This fish serves as a popular delicious dish. They have snake-like head). In most teleosts, the thyroid gland is composed of numerous follicles surrounding the arterial artery and the afferent bronchial blood vessel. [3], It grows to a length of 40cm. This fish contains 4 pairs of barbels and above features, hence it is Mystus seenghala. (1) Thyroid hormone plays an important role in oxygen uptake. The current study aims to assess the cadmium sub-lethal concentration influence on growth and haematological and biochemical parameters of Mystus seenghala. 1. Bony fishes have a sac-like outgrowth, the swim bladder (also called air bladder), arising from the dorsal wall of the oesophagus, which is air-filled organ, used to maintain balance and to swim up and down. There are also vascular ganglionic units that contain ganglionic cells, blood vessels, and the nervous system, and are located near or inside the parenchyma cells (Belsare 1973). . It is located near the pituitary gland. 9. CLASSIFICATION OF MYSTUS SEENGHALA Phylum :- CHORDATA ( Notochord and dorsal tubular nerve cord present and gill-slits present).

Assistance in adrenal cortical secretion control and melanogenesis. 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. The study of hormones is called hormonology. The idea is that all these heterotropic thyroid follicles migrate from the pharyngeal region to different parts of the body. 329 p. 2006 IUCN red list of threatened species. Moreover, estrogen controls the sexual behavior of the female fish. Almost all types of endocrine glands are present in the fish like in the upper vertebrates but their tissue and physiology are not clearly known. Their names are mentioned below: The pituitary gland is the most significant among the endocrine glands. Its secretion is called non-hormonal chemicals (such as sweat, milk, sebum, enzymes, etc.). It has a long snake like body. Five Mystus species (Figure 1) were collected from various sites of northern Kerala. FishBase. The sexual maturation of fish and the development of gametes take place in the presence of sex hormones. Which part of the male reproductive system store the sperm? Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. It is a fresh water fish and shows sexual dimorphism. 2019.
