Why do you think that carbohydrates are not digested in the stomach? The current study aims to assess the cadmium sub-lethal concentration influence on growth and haematological and biochemical parameters of Mystus seenghala. Prajadhipokia Fowler, 1934, Mystus is a genus of fish in the family Bagridae native to Asia. 1. Studies have shown that the interenal tissue of the teleost is hmologous part of the mammalian adrenal cortex and produces cortical steroids. Normally less active follicles contain thinner epithelium. These cells (internal cells) are eosinophilic in nature. simply extremely magnificent. Acidophils is pigmented with azocarmine or orange G pigment. The posterior-mid-dorsal growth of the epithelium from the posterior of the habenular produces this organ that passes through the anterior surface through the adipose connective tissue. <>>>

It is also called adrenal cortical tissue. sharing sensitive information, make sure youre on a federal In eel fish, these cells contain more grains which are more pigmented in alizarin and lead hematoxylin. Function: The hormone produced from these cells stimulates the adrenal cortical tissue to produce ACH and metabolize stored fats, water, carbohydrates and proteins. The study of endocrine glands is called endocrinology. Use of stored fats, protein formation and carbohydrates metabolism. In 1839, a scientist named Stannius first described the presence of this particle in the kidneys of sturgeon as a distinct glandular structure. The dried skin of the sea horse is used for the preparation of some ornaments. The endocrine system consists of a number of glands called endocrine glands which are spread over different areas of the fish body. In sharks and rays (Elasmobranchii) these nerves are located in the sympathetic chain of the nerve ganglia. I cant wait to read far more from you. This gland secretes hormones directly on their own and regulates the function of other glands by helping them secrete hormones. Description Body elongate and compressed; snout broad and spatulate.

In some species, such as Anguilla and Poecilia, two types of acidophils cells have been distinguished based on location, morphology, and pigmentation capacity. Different types of hormones are secreted from the endocrine glands. Hormones have to rely on certain external stimuli such as light, temperature and water chemistry to function.

Different species of teleost vary in the structure and extent of internal tissue. Iodinated amino acids: Iodine is combined with amino acids to produce iodinated amino acids such as thyroxine. Hormones are generally of four types, viz. 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. These studies have shown that pigment cells, the effect of hormones on germ cells, the function of the pituitary and thyroid glands, balance in movement, nitrogen metabolism (adrenal cortical tissue, thyroid gland), maturation of sex cells and reproductive behavior(pituitary galnd and sex hormones), the effect of hormones on metabolism (adrenal cortical tissue) have been proven. (2) Colloid cells (Colloid cells or Benstay`s cells) These cells contain granules of excretory material. A hormone is capable of influencing one or more reactions. The nervous system and the endocrine system existing in the animal body coordinate the functions of different systems. The brain bears relatively small olfactory lobes and cerebellum. Known from Ganga, Yamuna, Brahmaputra, Krishna, Godavary, and Cauvery river systems. Histologically, the thyroid gland is made up of numerous follicles.
