They are oval or round in shape and the number of cells in different species varies from 1-6. In sharks and rays (Elasmobranchii) these nerves are located in the sympathetic chain of the nerve ganglia. Mystus malabaricus (Jerdon) These cells of urophysis are called caudal neurosecretory system. Studies have shown that these cells secrete prolactin-like hormones. x=rG?#0!4p8gHk O)0a 53pzg|s~?_,..]\>Wvpik9Z}m7Ol|"+Segw//Q*3-3,3X^o?W2~C^Y4b/Y:~ & The islet of spleen is usually covered by epidermal cells. Teeth are found in pharynx only. One of these is the melaminophore stimulating hormone (Intermedin-MSH) and the other is the melanophore concentrating hormone (MCH-Melanophore Concentrating Hormone). The islets in Channa punctatus are located near the spleen and pylorus. The pineal sac forms a capsule covered by collagen connective tissue. In Lamprey (cyclostomata), endocrine internal cells are present throughout the body cavity adjacent to the posterior cardinal vein. It is located near the pituitary gland. 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. Sehgal P (1967) Food and feeding habits of Mystus seenghala Sykes. 7. Talwar, P.K. Function: Such cells help to increase body size. Specific physiological and biochemical tests have shown that these two types of hormones are secreted by teleosts but not readily available (Olivereau 1967). The study of hormones is called hormonology. Migrations should be cyclical and predictable and cover more than 100 km. The Animal Diversity Web is an educational resource written largely by and for college students. A.A. Balkema, Rotterdam. The concentration of fluoride ion was 1 1.0 ppm. 2019. Due to the presence of two types of cells, it is thought that they are involved in the production of two types of hormones. In Goldfish (Carassius auratus), Muller (1953) has been shown to increase their oxygen uptake by applying the hormone thyroxine, but Matty (1954) has shown that removal of the thyroid gland in the elasmobranch (surgical thyroidectomy) has no effect on respiration. The nervous system and the endocrine system existing in the animal body coordinate the functions of different systems. In many teleosts, such as Anguilla and Poecilia, the somatotropes are acidophils type and are located in the meso-adenohypophysis and are mixed with thyrotropes. All these activities are performed under the direction of the brain. 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. 12. The endocrine system consists of a number of glands called endocrine glands which are spread over different areas of the fish body. Intermediate conditions are observed in Clarias batrachus. Assists in electrolyte control and melanogenesis. It is found in clear and sluggish rivers and streams. Studies have shown that the interenal tissue of the teleost is hmologous part of the mammalian adrenal cortex and produces cortical steroids. The hormones are-. . Image Showing of Hormone Secretory Cells of Pituitary glands in Fishes. Hormones are important regulators that often regulate the metabolism of different types of living cells.

The nictitating membrane in the eye of fish is well developed. In most teleosts, the thyroid gland is composed of numerous follicles surrounding the arterial artery and the afferent bronchial blood vessel. It is also called proximal pars distalis. (2016). These hormones are secreted from the thyroid gland under the influence of thyrotropic hormones secreted from the pituitary gland. Research . Its cells can be divided into acidophils and cyanophils based on their pigmentation capacity. It then combines iodine with tyrosine to make thyroid hormone. This gland is attached to the roof of the Dianecephalon by the infandibulum. Comparative study of four Mystus species (Bagridae, Siluriformes) from Thailand: insights into their karyotypic diversity. Color is brownish-gray on back, silvery on flanks and belly. 205 ).
