Studies have shown that the release of stannius particles affects the kidneys, alters kidney function, and maintains electrolyte homeostasis. 14. The sperm, which resembles an open folded sac, produces spermatocytes. Biochemical parameters such as ALT, AST, total lipid and glucose level in Cd exposure groups were significantly higher, while the total protein level was significantly (P < 0.05) reduced in all treated groups as compared to control groups. 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.

[1] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages. They prepare secretin extract from the intestines of salmon, dogfish and skates. Hormones have to rely on certain external stimuli such as light, temperature and water chemistry to function. Removing stannius particles from Anguilla anguilla reduces the amount of plasma sodium and increases the concentration of potassium and calcium. Ledig cells or interstitial cells secrete testosterone, a hormone called androgen, from the interstitial space, the secretion of which is regulated by GTH.

You are making it enjoyable and you still care for to stay it wise. The endocrine gland is a type of ductless gland made up of different types of tissues and organs that produces and secretes one or more hormones and regulates the physiological functions of other body organs by direct blood flow. Elongated body is without scales. Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction. Gonadotropes, however, are not stained by AF. Moreover, some small islets are scattered in the mesentery. It is also called adrenal cortical tissue. Share Your PPT File.
