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
