gratituesday : contractions

in case you didn't know, "A uterine contraction is a muscle contraction of the uterine smooth muscle."  (http://en.wikipedia.org/wiki/Uterine_contraction).

during the woman's menstrual cycle, "The uterus frequently contracts throughout the entire menstrual cycle, and these contractions have been termed endometrial waves or contractile waves.[1] These appear to involve only the sub-endometrial layer of the myometrium.[1] In the early follicular phase, these contractions occur once or twice per minute and last 10–15 seconds with a low amplitude of usually 30 mmHg.[1] The frequency increases to 3–4 per minute towards ovulation. During the luteal phase, the frequency and amplitude decrease, possibly to facilitate any implantation.
If implantation does not occur, the frequency remains low, but the amplitude increases dramatically to between 50 and 200 mmHg producing labor-like contractions at the time of menstruation.[1] These contractions are sometimes termed menstrual cramps,[2] although that term is often used for menstrual pain in general. These contractions may be uncomfortable or even painful, but they are generally significantly less painful than contractions during labour. A hot water bottle or exercising has been found to help.
A shift in the myosin expression of the uterine smooth muscle has been hypothesized to avail for changes in the directions of uterine contractions that are seen during the menstrual cycle.
during pregnancy and "In obstetrics, a contraction may refer specifically to the motion of the uterus[3] as part of the process of childbirth. Contractions, and labour in general, is one condition that releases the hormone oxytocin into the body. Contractions become longer as labour intensifies.
Prior to actual labour, women may experience Braxton Hicks contractions, sometimes known as "false labour."
and lastly, in intercourse, "The uterus and vagina contract during female orgasm to encourage male semen to reach the fallopian tubes. These contractions may not be noticed by all women; pregnant women are more likely to notice these contractions by late 2nd and 3rd trimesters."

being female, i'm thankful for all three different types of contractions women experience.  lately though, i'm thankful for the second type listed most of all.  my uterus is doing what God designed it to do during this stage of my pregnancy.  they may hurt, but i know they're for the good.  i'm so glad my body is following His order...

Try to remember, "I can do all things through Christ who strengthens me."

as i re-read this post i realize that 1.) this information is very interesting if you're into fertility awareness.
2.) it's completely obvious that i was raised by a nurse!
