The exoskeleton, if present comprises cycloid, ctenoid or ganoid scales, which are dermal in origin. In Heteropneustes fossilis, Channa punctatus and Clarias batrachus, spontaneous degranulation and degeneration of beta cells occurs. Its secretion flows directly through the blood. 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. Its secretion is called non-hormonal chemicals (such as sweat, milk, sebum, enzymes, etc.). From an embryonic point of view, this gland develops from the pharyngeal epithelium near the fifth gill arch. The secretion from urophys is able to compress the smooth muscles of the ovaries and fallopian tubes of the guppy fish (Poecilia reticulata) and the sperm of the Gallichthys mirabilis. In bony fish it is located along the arterial artery, in cartilage fish along the midline of the tongue muscle.

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). Elongated body is without scales. 5. The endocrine glands usually control the long-term activity of the target organ and control various physiological processes such as digestion, metabolism, growth, development, reproduction, etc. Although the endocrine glands have similarities with the upper vertebrae, some differences can be observed due to living in the aquatic environment. version (08/2021). It is found only in the Burnett and Mary rivers of Queens-land in Australia. Findings revealed that the growth of three treated variant length groups was affected negatively by cadmium exposure and showed significantly (P < 0.05) lower average wet weight, body length and condition factor as compared to control groups, while the feed conversion ratio (FCR) increases by increasing the exposure duration. The idea is that all these heterotropic thyroid follicles migrate from the pharyngeal region to different parts of the body. Give an example. These effects can be irritating or disruptive to work. Hydrobiologia 54(3):219-224. These two tissues are so closely related that they are considered together as neuro intermediate lobes.

Mystus cavasius, the Gangetic mystus, is a species of catfish of the family Bagridae.. its classification into particular taxa, Morphometry is an important tool (3). Mystus seenghalaare called as sykes due to the presence of barbels. (1) Thyroid hormone plays an important role in oxygen uptake. 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. Function: The hormone produced from these cells stimulates the adrenal cortical tissue to produce ACH and metabolize stored fats, water, carbohydrates and proteins. Initially, Sykes (1839) described this species as Platystoma seenghala. Meta-adenohypophysis:It is usually located in the posterior part of the hypophysis. Editors. Water quality parameters were kept constant during the entire course of the research, and the major parameters were measured as temperature (28.03 0.03 C), DO (5.82 0.14 mg L-1), pH (8.00 0.01) and total hardness (249.98 0.01 mg L-1).
