These form singles or groups within the adrenal cells or form adrenal complexes jointly with the adrenal glands. All these activities are performed under the direction of the brain. It is histologically similar to the parathyroid glands of the upper vertebrae. Based on the origin, the components of the endocrine system are divided into the following: (1) Discrete endocrine glands: Such glands are pituitary (hypophysis), thyroid and pineal. FishBase. Recent studies on Mystus vittatus shown that the pineal organ affects the maturation of fish gonads. J Fish Aquat Sci 5:113119. 1 0 obj In some teleosts such as Phoxinus, Rutilus and Astyanax, thyrotrophs aldehydes are used to stain fuchsin (AF). achromogenes. Peptide. Beta cells are polyhedral-shaped cells with large spherical nuclei. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. In Clarias batrachus, Heteropneustes fossilis, and Mystus seenghala, the exocrine glands are more precise, and the largest part is located in the mesentery along the blood vessels or bile ducts between the two lobes of the liver. No Data. In the caudal neurosecretory system, neurosecretory cells extend to the margins of the spinal cord. They are thought to secrete adrenocorticotropic hormones. It contains acidophils, cyanophils and chromophobes. c_6 6~Y5yOW?3\]c(+S@n7.~wK4ievmRxSTztRU^%!SZ%!% It is found only in the Burnett and Mary rivers of Queens-land in Australia.
