Pituitary gland and its relation to the reproduction of fishes in nature and in captivity by James W. Atz Download PDF EPUB FB2

The pituitary gland is a small endocrine organ that controls a multitude of important functions in the body. It is divided into an anterior lobe, intermediate zone, and posterior lobe, all of which are involved in either hormone production or hormone secretion.

The pituitary gland is termed the "Master Gland" because it directs other organs and endocrine glands to either suppress or induce Author: Regina Bailey. In vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland, about the size of a pea and weighing grams ( oz) in humans.

It is a protrusion off the bottom of the hypothalamus at the base of the hypophysis rests upon the hypophysial fossa of the sphenoid bone in the center of the middle cranial fossa and is surrounded by a small bony cavity (sella turcica Artery: superior hypophyseal artery, infundibular.

Pituitary gland, also called hypophysis, ductless gland of the endocrine system that secretes hormones directly into the bloodstream. The term hypophysis (from the Greek for “lying under”)—another name for the pituitary—refers to the gland’s position on the underside of the pituitary gland is called the “master gland” because its hormones regulate other important.

Introduction to endocrine glands of fishes S.M. Abu Naser The glands that secrete their products into the bloodstream and body tissues along with the central nervous system to control and regulate many kinds of body functions are known as endocrine gland. The hormone secreted by pituitary gland stimulates growth, development, maturity and ovulation of eggs.

These hormone secreted from pituitary are protein or peptide. Collection of Pituitary Gland: The gland should preferably be collected from fully ripe gravid fishes, as the gland is most potent at the time of breeding or just before spawning.

Fish Pituitary Gland 1. Fish Pituitary gland 2. Structure: • Pituitary gland is an endocrine gland situated on the ventral side of the brain • It is a small, soft, whitish body whose size and shape vary with species • It is more or less round in carps; oval in catla and rohu and pear-shaped in mrigal • The pituitary is located in a concave cavity known as Sella turcica and enclosed by.

The pituitary gland is one of the principal glands of the endocrine system. It releases at least nine hormones affecting a wide variety of body functions, including growth, reproduction, and levels of electrolytes and water in the body fluids. The pituitary sits near the center of the head, behind the nose and beneath the brain, just below the hypothalamus.

The presence of follicle stimulating hormone in fishes (FSH), which is the second gonadotropin hormone found in mammalian pituitary gland, is still not confirmed.

Recently, prostaglandin, which is hormone-like substance has been isolated from testis and semen of bluefin tuna, Thynnus thynnus and flounder (Paralichthys olivaceus).

PITUITARY GLAND ANATOMY The hypothalamus is responsible for creating the hormones which the neurohypophysis of the pituitary gland releases into the human body.

Alternatively, the adenohypophysis of the pituitary gland is able to create and secrete its own hormones. These hormones are actually created as a response system to the hormones released by the neurohypophysis as a regulatory action.

The pituitary gland is situated in a depression the sella turcica of sphenoid bone of the skull. The. The pituitary gland (hypophysis) is attached to the bottom of the hypothalamus by a slender stalk called the infundibulum.

The pituitary gland consists of two major regions: the anterior pituitary gland (anterior lobe or adenohypophysis) and the posterior pituitary gland (posterior lobe or neurohypophysis). The endocrine system works in the way where a signal is sent from a part of the body to the hypothalamus, and then the hypothalamus sends a signal to the pituitary gland.

After the signal, a hormone is produced in the pituitary and sent to the rest of. Below is information about the structure and function of the canine pituitary gland. We will tell you about the general structure of the pituitary gland, how the pituitary gland works in dogs, common diseases that affect the pituitary gland and common diagnostic tests performed in dogs to evaluate the gland.

Pituitary gland Definition. The pituitary gland is located at the base of the brain and is part of the endocrine is sometimes called the hypophysis, from two Greek words that mean "to grow beneath." The pituitary is responsible for the hormonal regulation of several body processes, including water retention, breast milk synthesis and release, human growth, and thyroid gland secretions.

Pituitary gland. The most structurally and functionally complex organ of the endocrine system. Through its hormones, the pituitary, also known as the hypophysis, affects every physiological process of the body. All vertebrates have a pituitary gland with a common basic structure and function. - Interacts w/ anterior pituitary gland through the hypophyseal portal system - Hypophyseal portal system = capillary system so the capillaries flow b/w hypothalamus & pituitary gland - Hypothalamus secretes hormones into this system & they go down and signal pituitary gland example of.

Pituitary gland. The pituitary gland (also called 'master gland') is a pea sized gland located at the base of the brain. It secretes hormones that control the development and function of different organs in the body. Hormones are chemical messengers that influence the functioning of their target organs.

The pituitary gland Or pituitary gland is an endocrine gland that secretes hormones responsible for regulating the body's homeostasis.

It regulates the function of other glands of the endocrine system and its functioning is conditioned by the Hypothalamus, A region of the brain. Fishes pituitary gland. "The truth about mobile phone and wireless radiation" -- Dr Devra Davis - Duration: The University of Melbourne Recommended for you.The normal function of the pituitary gland is most commonly disrupted by the presence of a pituitary tumour.

Please be assured that these are benign tumours and not cancerous. Pituitary tumours are actually swellings in the pituitary - as they grow they may destroy the cells in the pituitary that produce hormones including the gonadotrophins.
