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

This book describes Ovum, Functions, Diseases, Diagnosis and Treatment and Related Diseases

My name is Lazy Lucy the unfertilized ovum cell.
I was named Lazy Lucy by my friends who think that I like to laze around.
It is true that I like to laze around.
I am surrounded by the follicular fluid in the follicle and the 5 million granulosa cells.
I like to float in my follicle enjoying the nutrients from my so called lake,
Suddenly I was released into the abdominal cavity where the fimbriae of the oviduct pick me up to float in the fallopian tube.
My ovum is released into the abdominal cavity near the opening of one of the oviducts or Fallopian tubes.
Tiny hairs in the oviduct set up currents that draw me in.
There I was pushed along by tiny hairs together towards the uterus.
I was enjoying myself in the floating journey
Suddenly a pack of sperms suddenly floats towards me.
I was under attack by a group of sperm cells.
They tried to push their heads into my cell membrane.
Somehow one of them manages to get through.
He was a particularly cute sperm with a very cheeky face.
I fell in love with him immediately.
Our chromosomes merge and we started dividing to form a baby.
We managed to implant our embryo in the uterus without problem.
We were quite lucky to get a good location in the womb to implant our baby.

The ovum is the largest cell in the human body being visible to the naked eye, at 0.12 mm in length
Ova are produced in the ovaries but these are not fertilized eggs and will never complete meiosis until they are first fertilized by a sperm.
Inside the ovary a follicle consists of one ovum cell surrounded by special cells called granulose cells to nourish and protect it.
A human female normally has about 40,000 follicles with potential ova all formed before birth.
Only about 400 of these ova will actually ever be released during her reproductive years.
Normally, in humans after the onset of puberty, due to the stimulation of follicular-stimulating-hormone (FSH) one ovum per cycle matures and is released from its ovary.
The left ovary will release an ovum cell on one month and the next month the right ovary will release another ovum.

Ovulation is the release of a mature ovum due to the stimulation of luteinizing hormone (LH), which then stimulates the remaining follicle cells to turn into a corpus luteum.
The corpus luteum then secretes progesterone to prepare the uterus for possible implantation.
If an egg is not fertilized by a sperm and does not become a fetus, the corpus luteum breaks up and when it stops producing progesterone, the lining of the uterus breaks down and is shed as menses.
Each ovum cell is released into the abdominal cavity near the opening of one of the oviducts or Fallopian tubes.
Cilia in the oviduct set up currents that draw the ovum in.
If sperm are present in the oviduct , the ovum will be fertilized near the far end of the Fallopian tube and will finish meiosis.
The embryo will begin to divide and grow as it moves to the uterus
The trip down the Fallopian tube takes about a week as the cilia in the tube propel the fertilized egg down to the uterus.
The fertilized egg is called an embryo.
At this point the woman has no idea whether an unfertilized egg or a new baby is traveling down that tube.
During this time, progesterone produced by the corpus luteum has been invigorating the endometrium (the lining of the uterus) to thicken in preparation for possible implantation.
When a growing embryo ultimately reaches the uterus, it will implant in this nutritious environment and start to secrete its own hormones to maintain the endometrium.

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

The Ovum

What is an Ovum?

The ovum is the largest cell in the human body being visible to the naked eye, at 0.12 mm in length, just as the sperm is the smallest cell in the body.

Ova are produced in the ovaries but these are not fertilized eggs and will never complete meiosis (cell division) until they are first fertilized by a sperm.

Inside the ovary a follicle consists of one ovum cell surrounded by special cells called granulose cells to nourish and protect it.

A human female normally has about 40,000 follicles with potential ova all formed before birth.

Only about 400 of these ova will actually ever be released during her reproductive years.

Normally, in humans after the onset of puberty, due to the stimulation of follicular-stimulating-hormone (FSH) one ovum per cycle matures and is released from its ovary.

The left ovary will release an ovum cell on one month and the next month the right ovary will release another ovum.

What is Ovulation?

Ovulation is the release of a mature ovum due to the stimulation of luteinizing hormone (LH), which then stimulates the remaining follicle cells to turn into a corpus luteum (secretory structure which forms from remains of ovarian follicle).

The corpus luteum then secretes progesterone to prepare the uterus for possible implantation.

If an egg is not fertilized by a sperm and does not become a fetus, the corpus luteum breaks up and when it stops producing progesterone, the lining of the uterus breaks down and is shed.

Each ovum cell is released into the abdominal cavity near the opening of one of the oviducts or Fallopian tubes.

Cilia (tiny hairs) in the oviduct set up currents that draw the ovum in.

If sperm are present in the oviduct (after sexual intercourse), the ovum will be fertilized near the far end of the Fallopian tube and will finish meiosis.

The embryo will begin to divide and grow as it moves to the uterus.

The trip down the Fallopian tube takes about a week as the cilia in the tube propel the fertilized egg down to the uterus.

The fertilized egg is called an embryo.

A t this point the woman has no idea whether an unfertilized egg or a new baby is traveling down that tube.

During this time, progesterone produced by the corpus luteum has been invigorating the endometrium (the lining of the uterus) to thicken in preparation for possible implantation.

When a growing embryo ultimately reaches the uterus, it will implant in this nutritious environment and start to secrete its own hormones to maintain the endometrium.

If the ovum is not fertilized, it dies and disintegrates.

The corpus luteum also disintegrates; its progesterone production falls, and the unneeded, built-up endometrium is shed as menstrual blood.

The uterus is very small and has thick, muscular
