It undergoes aestivation during summer season. (4) It acts in the same way as the mammalian adrenal medulla, so the chlomafin tissue of the teleost is considered to be a homologous organ of the adrenal medulla of mammals.

This gland is small in size and paired and is located on the horizontal membrane or near the thyroid gland in the space between the abdominal cavity and the sinus venosus on the left side of the esophagus. Yonar ME, Mie Yonar S, spir , Ural M. In bony fish it is located along the arterial artery, in cartilage fish along the midline of the tongue muscle. According to Gill and Punetha (1977), the mountain river Pseudoecheneis salcatus has 1-2 stannius corpuscles located 10 mm away from the excretory genitalia. Webrian ossicles present between air bladder and ear). It feeds on the mosquito larvae; therefore, it is widely used to control mosquito larvae. The trunk and tail bear moderate sized scales. Moreover, estrogen controls the sexual behavior of the female fish. Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction. They have snake-like head). They are oval or round in shape and the number of cells in different species varies from 1-6. Name the types of nitrogenous bases present in the RNA.

It is found in clear and sluggish rivers and streams. On the other hand, endocrine glands do not have any ducts, so endocrine glands are called ductless glands. 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. The below mentioned article provides biology notes on Class Osteichthyes. Some researchers have identified the pineal gland of fish as a light-sensitive and secretory organ. 4. Later, the generic name of this species has undergone several replacements (Bagrus, Aorichthys, Mystus) and currently it is placed under the genus Sperata (Ferraris and Runge, 1999). In Clarias batrachus, Heteropneustes fossilis, and Mystus seenghala, the exocrine glands are more precise, and the largest part is located in the mesentery along the blood vessels or bile ducts between the two lobes of the liver.

In some fish, especially goldfish, trout, salmon, etc., this particle is found to be flat, white, and oval in shape on the peritoneal surface. Editors. These are usually called paracrine cells (such as somatostatin). The male bears a brood pouch in which the female lays eggs and the latter remain there till they hatch. The endocrine system mainly controls the relatively slow metabolism of carbohydrates and water through the adrenal cortical tissue, the metabolism of nitrogen through the adrenal cortical tissue and thyroid gland, and the maturation and sexual behavior of germ cells through the pituitary and sex hormones.

In the lamprey (Cyclostomata) chromafin cells are located along the portal veins of the dorsal aorta, ventricle and heart in the form of a thread. Table: Difference Between Hormone and EnzymeHormoneEnzymeHormones are secreted from the endocrine glands.Enzymes are secreted from the exocrine glands.Hormones are called chemical messengers.Enzymes are called organic catalysts.Hormones reach the destination either directly or through the blood.The enzyme is transported from the place of origin through the duct to the destination.Hormones are made up of peptides and proteins or amines or steroids or fatty acids derivatives.The enzyme is made up of globular proteins.Hormones are destroyed after biochemical reactions.Enzymes are not destroyed through biochemical reactions.A hormone is capable of influencing one or more reactions.An enzyme is only able to act as a catalyst in a particular reaction.They are dynamic and arise in one place and act in another.They are located in all the cells and act in that place.It plays a role in controlling physical growth or decline, color, and sexual characteristics etc.It controls all the biochemical reactions in the cell.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'biologyeducare_com-leader-1','ezslot_4',560,'0','0'])};__ez_fad_position('div-gpt-ad-biologyeducare_com-leader-1-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'biologyeducare_com-leader-1','ezslot_5',560,'0','1'])};__ez_fad_position('div-gpt-ad-biologyeducare_com-leader-1-0_1');.leader-1-multi-560{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:15px!important;margin-left:auto!important;margin-right:auto!important;margin-top:15px!important;max-width:100%!important;min-height:250px;min-width:250px;padding:0;text-align:center!important;width:100%}. `? 4WA! wt5x found in river Amazon and Paraguay basin in South America developed barbels registered of.
