Pituitary Gland, Functions, Diseases, A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

By Kenneth Kee

This book describes Pituitary gland, Functions, Diseases, Diagnosis and Treatment and Related Diseases
The fully developed pituitary gland or hypophysis is a pea-sized endocrine gland and weighs about 0.5 g.
The adenohypophysis comprises roughly 80% of the pituitary and produces an array of peptide hormones.
The release of these pituitary hormones is mediated by hypothalamic neurohormones that are secreted from the median eminence (a site where axon terminals originate from the hypothalamus) and that reach the adenohypophysis through a portal venous system.
The pituitary gland is often indicated as the "master gland" of the body, since it controls many activities of other endocrine glands.
Situated above the pituitary gland is the hypothalamus.
The hypothalamus makes the decisions which hormones the pituitary should secrete by sending it either hormonal or electrical messages.
In reaction to hormonal messages from the hypothalamus, the pituitary gland secretes these:
1.GH
2.TSH
3.FSH
4.LH
5.Prolactin
6.ACTH
7.MSH
In response to electrical messages from the hypothalamus, the pituitary gland secretes these:
1.ADH
2.Oxytocin
The pituitary gland is enclosed by dura and locates within the sella turcica of the sphenoid bone.
The sella turcica is a saddle-shaped depression that encloses the inferior, anterior, and posterior aspects of the pituitary

Life and Death of a Pituitary gland cell
My name is Pituitary Man the Pituitary Gland Cell.
I was named Pituitary Man by my friends who feel that Pituitary Man n is the most suitable name of a cell from the Pituitary Gland of the human body.
We pituitary gland cells do not just spring into existence from embryo stem cells.
The path of our development begins in a group of pituitary duct cells that are nudged into different directions to become specialized cells of many different tissues and organs including the pituitary gland.
It has long been known that we pituitary gland development begins in the fore gut and the third ventricle of the brain of the very early embryo before the embryo begins to mature into the recognizably human form of a fetus.
My Pituitary gland is a combination of two tissues.
1.My Anterior lobe or adenohypophysis
2.My Posterior lobe or Neurohypophysis
My hypothalamo-pituitary axis is completed by 20 weeks gestation.
My pituitary gland is functionally connected to the hypothalamus by the median eminence via a small tube called the infundibular stem
As the master gland of the body, I produce and secrete many hormones that travel throughout the body directing certain processes stimulating other glands to produce different types of hormones.
My anterior pituitary gland synthesizes and secretes the endocrine hormones:
ACTH, FSH, LH, TSH, Prolactin, MSH, GH
Hypothalamic hormones are secreted to my anterior pituitary lobe by way of a special capillary system called the hypothalamic-hypophysial portal system
My posterior lobe develops as an extension of the hypothalamus.
My posterior pituitary stores and secretes the endocrine hormones:
Oxytocin, ADH
Hormones secreted from my pituitary gland help control:
1.Growth
2.Blood pressure
3.Aspects of pregnancy and childbirth
4.Breast milk production
5.Sex organ functions in both males and females
6.Thyroid gland function
7.Parathyroid gland function
8.The conversion of food into energy
9.Water and osmolarity regulation in the body
10.Temperature regulation
11.Pain relief
My anterior pituitary gland cells are able to live at least 20 years or more.
Regeneration normally occurs after apoptosis.
Death of my pituitary gland cells is by apoptosis or necrosis.

Introduction

I have been writing medical articles for my blog: http://kennethkee.blogspot.com (A Simple Guide to Medical Disorder) for the benefit of my patients since 2007.

My purpose in writing these simple guides was for the health education of my patients.

Health Education was also my dissertation for my Ph.D (Healthcare Administration).

I then wrote an autobiolographical account of his journey as a medical student to family doctor on his other blog: http://afamilydoctorstale.blogspot.com.

This autobiolographical account A Family Doctor’s Tale was combined with my early A Simple Guide to Medical Disorders into a new Wordpress Blog A Family Doctor’s Tale on http://kenkee481.wordpress.com.

From which many free articles from the blog was taken and put together into 800 eBooks.

Some people have complained that the simple guides are too simple.

For their information they are made simple in order to educate the patients.

The later books go into more details of medical disorders.

The first chapter is always from my earlier blogs which unfortunately tends to have typos and spelling mistakes.

Since 2013, I have tried to improve my spelling and writing.

As I tried to bring the patient the latest information about a disorder or illness by reading the latest journals both online and offline, I find that I am learning more and improving on my own medical knowledge in diagnosis and treatment for my patients.

Just by writing all these simple guides I find that I have learned a lot from your reviews (good or bad), criticism and advice.

I am sorry for the repetitions in these simple guides as the second chapters onwards have new information as compared to my first chapter taken from my blog.

I also find repetition definitely help me and maybe some readers to remember the facts in the books more easily.

I apologize if these repetitions are irritating to some readers.

Chapter 1

Pituitary Gland

The fully developed pituitary gland or hypophysis is a pea-sized endocrine gland and weighs about 0.5 g.

The adenohypophysis comprises roughly 80% of the pituitary and produces an array of peptide hormones.

The release of these pituitary hormones is mediated by hypothalamic neurohormones that are secreted from the median eminence (a site where axon terminals originate from the hypothalamus) and that reach the adenohypophysis through a portal venous system.

The pituitary gland is often indicated as the master gland of the body, since it controls many activities of other endocrine glands.

Situated above the pituitary gland is the hypothalamus.

The hypothalamus makes the decisions which hormones the pituitary should secrete by sending it either hormonal or electrical messages.

In reaction to hormonal messages from the hypothalamus, the pituitary gland secretes these:

1. GH (growth hormone) - raises size of muscle and bone

2. TSH (thyroid stimulating hormone) - activates the thyroid gland to release T3 and T4 to stimulate metabolism in other cells throughout the body

3. FSH (follicle stimulating hormone) - activates ovarian follicle production in women; activates sperm production in men

4. LH (luteinizing hormone) - activates ovaries to produce estrogen in women; activates sperm production in men

5. Prolactin - activates breast tissue in nursing mothers to produce milk

6. ACTH
