However, as a result of the proliferation of multiple branches of the parenchyma (Neurohypophysis), it can be easily distinguished from meta-adenohypophysis. So these two systems are called integrated systems. The pituitary gland is mainly divided into two parts based on the cell structure, relative position, presence of secretory cells and pigmentation capacity of different parts of the pituitary gland, viz. From an embryonic point of view, this gland develops from the pharyngeal epithelium near the fifth gill arch. 10. When she failed to identify it, she sent its sketch to Professor J.L.B.

It is a fresh water fish inhabiting all the rivers in India. In some fishes, such as Heteropneustes, it helps in respiration. There are two main types of cells in the epithelium. 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. 8. Smith, an eminent Ichthyologist of Rhodes University College at Grahams town. 7. of fluoride on haematological parameters of fish Mystus seenghala was investigated. In the case of sharks (Squaliformes) it is located in the middle of the kidney. This fish is also eaten. In some fish, especially goldfish, trout, salmon, etc., this particle is found to be flat, white, and oval in shape on the peritoneal surface. It plays a role in controlling physical growth or decline, color, and sexual characteristics etc. It is the most preferred fish species for eating in the north and north-western states of India be-cause of its tasty flesh and the low number of intramuscu-lar bones. They are bigger in size and their growth rate is faster, e.g., Labeo rohita, Labeo calbasu, Cirrhinus mrigala, Catla catla, Ctenopharyngodon idella (Grass carp). Some researchers have referred to the agranuloid cells of some fish as C cells and A2 cells as D cells. Colouration varies according to habitat.

Use of stored fats, protein formation and carbohydrates metabolism. The neck and the head of the fish are horse-like and the tail is prehensile. On the other hand, endocrine glands do not have any ducts, so endocrine glands are called ductless glands. The largest islet in the Tor tor is pin in shape, located near the bile duct. The enzyme is transported from the place of origin through the duct to the destination. Disclaimer: Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.

Elongated body is without scales. Its secretion flows directly through the blood. 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. Hormones are therefore called chemical messengers. Elongated body is without scales. National Science Foundation From histological point of view, each stannius particle consists of parenchymal cells.
