Today’s A – Z Challenge post is brought to you by the letter “U”

A to Z Challenge

I am so excited to take part in this, my second, A – Z Challenge!  Last year I did the challenge using “recipes” as my inspiration.  Well, this year I’m going to draw on my nursing background and use “parts of the human body” as my inspiration!  Hmmm…a part of the body that starts with “Q”, “X” or “Z”….

It should be a lot of fun and I’m looking forward to seeing how everyone interprets the Challenge!

So, without further ado,  “U”  is for Uterus:  

A - Z Challenge

The uterus is an inverted pear-shaped, hollow, thick-walled, muscular organ situated  in the pelvic cavity between the bladder and rectum.

It consists of three layers, they are called, from innermost to outermost, the:

  • Endometrium – The lining of the uterine cavity is called the “endometrium.”  Shedding of the  endometrial lining is responsible for menstruation.
  • Myometrium – The bulk of the uterus consists of smooth muscle, known as “myometrium.”
  •  Perimetrium – The tissue surrounding the outside of the uterus is called the “perimetrium.”

In the upper, dome shaped “fundus”,  the fallopian tubes open, one on either side.  Below the fundus is the body of the uterus and below the body is the cervix, which communicates with the vagina..

When ova are discharged from the ovaries they are carried to the uterine cavity through the fallopian tubes. If an ovum is fertilized it imbeds itself in the uterine wall and is normally retained in the uterus until prenatal development is completed.

Surgical removal of the uterus is called a Hysterectomy.  If the fallopian tubes and ovaries are also removed it is a Hysterectomy with Bilateral Salpingo-Oopherectomy.

U is also for: 

umbilical cord A cordlike structure containing the umbilical arteries and vein and connecting the fetus with the placenta.

umbilicus  The site where the umbilical cord was attached to the fetus; commonly called the navel.

ureter  A tube that transports urine from the kidney to the urinary bladder.

urethra  A tube that transports urine from the urinary bladder to the outside of the body.

urinary bladder  A distensible sac that stores urine, situated in the pelvic cavity posterior to the symphysis pubis.

uvula  A fleshy, pendulous portion of the soft palate that blocks the nasopharynx during swallowing.

I found the above definitions at the McGraw-Hill Applied Biology Resource Center.  Visit their site and you’ll be amazed to know there are even more “U” parts of the body listed there!

  1. Very informative post, Monica. I’m glad you’re a gyne. nurse and could get us through the pronouncation of those procedures!! When this is all over, we’ll know where to come for all the information on body parts.
    Great post!!

  2. Hey, great “U” post….however if I was doing it, it would be under the letter”R” for “removed” or “H” for “hysterectomy”! Kathy is right, your “gyney” experience is shining through!! 5 Letters to go!!!!
