Thyroid Gland, Function, Diseases, A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

by Kenneth Kee

Overview

This book describes Thyroid Gland, Function, Diseases, Diagnosis and Treatment and Related Diseases
The thyroid gland is a very vital endocrine gland sited in the front of the neck below the larynx
The two-inch gland comprises two lobes, one on each side of the windpipe joined by tissue called the isthmus.
It has a primary function in the metabolism, growth and development of the human body.
It helps to regulate many body functions by constantly secreting a steady amount of thyroid hormones into the bloodstream.
If the body needs more energy in certain circumstances if it is growing or cold, or during pregnancy, the thyroid gland produces more hormones.
The thyroid secretes 3 important hormones – tri-iodothyronine (T3), thyroxine (T4) and calcitonin.
Life and Death of a thyroid gland cell:
My name is Energy Man the Thyroid Gland Cell.
I was named Energy Man by my friends who feel that Energy Man is the most suitable name of a cell from Energy Inducing Thyroid gland of the human body.
In the fetus at 3-4 weeks of gestation, our thyroid gland appears as an epithelial proliferation in the floor of the pharynx at the base of the tongue between the tuberculum impar and the copula linguae at a point later indicated by the foramen cecum.
Our thyroid gland then descends in front of the pharyngeal gut as a bi-lobed diverticulum through the thyroglossal duct.
Over the next few weeks, we migrate to the base of the neck passing anterior to the hyoid bone.
Thyrotropin-releasing hormone (TRH) and thyroid-stimulating hormone (TSH) start being secreted from the fetal hypothalamus and pituitary at 18-20 weeks of gestation, and fetal production of our thyroxine (T4) reach a clinically significant level at 18–20 weeks.
Our Fetal triiodothyronine (T3) remains low (less than 15ng/dL) until 30 weeks of gestation, and increases to 50ng/dL at term.
Preterm births can suffer neurodevelopmental disorders due to lack of maternal thyroid hormones due their own thyroid being insufficiently developed to meet their postnatal needs.
The portion of our thyroid gland containing our parafollicular C cells responsible for the production of calcitonin is derived from the neural crest.
The ultimobranchial body joins our primordial thyroid gland during its descent to its final location in the anterior neck.
My thyroid tissue is made up of 2 types of cells:
1.Most of my thyroid tissue consists of the follicular cells which secrete my iodine-containing hormones called thyroxine (T4) and triiodothyronine (T3).
2.My parafollicular cells which are clear cells (C cells) secrete the hormone calcitonin to control the blood calcium
My thyroid needs iodine to produce the hormones.
My T4 and T3 hormones stimulate every tissue in the body to produce proteins and body energy.
My thyroid hormones increases growth and metabolism and are stored bound to a protein called thyroglobulin in the colloid of my follicles.
My calcitonin hormone works together with the parathyroid hormone to regulate calcium in the body.
My thyroid hormones regulate how the body breaks down the food we eat.
The levels of hormones secreted by my thyroid are controlled by the pituitary gland's thyroid-stimulating hormone (TSH) which in turn is controlled by the hypothalamus.
My T3 also stimulates growth and development of the brain and bones.
Since my thyroid cells produce my thyroid hormone which is also a growth hormone, there is very little our cells lost during the life span of my thyroid gland.
Apoptosis of my thyroid cells as usual helps to regenerate cells that are lost.
Even then our cells volume becomes lesser every year.
Necrosis of my thyroid gland can cause the death of my thyroid gland.

About the Author

Medical doctor since 1972. Started Kee Clinic in 1974 at 15 Holland Dr #03-102, relocated to 36 Holland Dr #01-10 in 2009. Did my M.Sc (Health Management ) in 1991 and Ph.D (Healthcare Administration) in 1993. Dr Kenneth Kee is still working as a family doctor at the age of 65. However he has reduced his consultation hours to 3 hours in the morning and 2 hours in the afternoon. He first started writing free blogs on medical conditions seen in the clinic in 2007 on http://kennethkee.blogspot.com. His purpose in writing these simple guides was for the health education of his patients which is also his dissertation for his Ph.D (Healthcare Administration). He then wrote an autobiolographical account of his journey as a medical student to family doctor on his other blog afamilydoctorstale.blogspot.com. This autobiolographical account “A Family Doctor’s Tale” was combined with his early “A Simple Guide to Medical Conditions” into a new Wordpress Blog “A Family Doctor’s Tale” on http://ken-med.com. From which many free articles from the blog was taken and put together into 550 amazon kindle books and some into Smashwords.com eBooks. He apologized for typos and spelling mistakes in his earlier books. He will endeavor to improve the writing in futures. 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 conditions. The first chapter of all my ebooks is always taken from my blog A Simple Guide to Medical Conditions which was started in 2007 as a simple educational help to my patients on my first blog http://kennethkee.blogspot.com. The medical condition was described simply and direct to the point. Because the simple guide as taken from the blog was described as too simple, I have increased the other chapters to include more detailed description of the illness, symptoms, diagnosis and treatment. As a result there are the complaints by some readers of constant repetitions of the same contents but in detail and fairly up to date. He has published 550 eBooks on various subjects on health, 1 autobiography of his medical journey, another on the autobiography of a Cancer survivor, 2 children stories and one how to study for his nephew and grand-daughter. The purpose of these simple guides is to educate patient on health conditions and not meant as textbooks. He does not do any night duty since 2000 ever since Dr Tan had his second stroke. His clinic is now relocated to the Bouna Vista Community Centre. The 2 units of his original clinic are being demolished to make way for a new Shopping Mall. He is now doing some blogging and internet surfing (bulletin boards since the 1980's) starting with the Apple computer and going to PC. All the PC is upgraded by himself from XT to the present Pentium duo core. The present Intel i7 CPU is out of reach at the moment because the CPU is still expensive. He is also into DIY changing his own toilet cistern and other electric appliance. His hunger for knowledge has not abated and he is a lifelong learner. The children have all grown up and there are 2 grandchildren who are even more technically advanced than the grandfather where mobile phones are concerned. This book is taken from some of the many articles in his blog (now with 740 posts) A Family Doctor’s Tale. Dr Kee is the author of: "A Family Doctor's Tale" "Life Lessons Learned From The Study And Practice Of Medicine" "Case Notes From A Family Doctor"
