The small islet is scattered among the mass of the cell, separated by a thick connective tissue. It contains acidophilic cells which are stained with azocarmine and orange G. In some fish species, a significant number of such acidophilic cells, such as follicular structures, surround the blood capilaries. All hormones are made up of proteins or polypeptides. In fish such as Poecilia, these cells are granular long chromophobic types. These cells (internal cells) are eosinophilic in nature. External nares lie on the dorsal surface of the snout. Different types of hormones are secreted from the endocrine glands. It operates near the point of origin or in the distant target area. Fishes have very close relationship with their environment. In Mystus aor, it resembles sagitate, in Bagarius bagarius it resembles a rosette or rose, in Wallago attu it is angular and in Nangra punctata it is funnel-shaped. Mystus seenghalaare called as sykes due to the presence of barbels. It makes identification taxonomically significant. Carps have toothless mouth with scales on the body; however, head is without scales. However, in some fish such as Parrotfish (Spariidae), Swordfish (Xiphias gladius), Gymnarchus niloticus and Thynnus thynnus it is densely packed and covered. 1984). All have three chambered heart (two auricles and one ventricle). 2022 Nov 12. doi: 10.1007/s12011-022-03477-z. 4 0 obj The extracellular mass contains a significant number of pancreatic islets of various shapes. Its size varies widely among different species. version (08/2021). 329 p. 2006 IUCN red list of threatened species. It is derived from the Greek word Hormao which means to excite. A total of 60 fish of three different length groups (20 each) were collected from Head Qadirabad, Pakistan.

The sperm, which resembles an open folded sac, produces spermatocytes. 2008 Jun;34(2):169-74. doi: 10.1007/s10695-007-9157-2. Darshan, Abujam, Humar, Parhi, Singh, et al. It releases two types of hormones, such as arginine vasotocin and oxytocin. Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction. The pineal gland secretes melatonin hormone and sulfate acid mycopolysaccharides, basic proteins (proteins arginine and lysine amino acids), common lipids, acidic lipids, phospholipids, basophil-rich neurosecretory components containing gamma components. Other types of cells are stained with azacarmine or erythrosine (prolactin cells). Mystus: The Cat Fish: Mystus seenghala is a common fresh water cat fish. 8. However, as a result of hyperglycemia, beta cells are destroyed by taking beta-cytotoxic drugs such as aloxacin and streptozotocin. Some researchers have referred to the agranuloid cells of some fish as C cells and A2 cells as D cells. Phylum:-CHORDATA ( Notochord and dorsal tubular nerve cord present and gill-slits present).
