The Uterus in pregnancy



During pregnancy the uterus grows upwards out of the woman's pelvis. The top of the uterus (or fundus) can be felt by your caregiver feeling your belly after about 12 weeks of pregnancy. By 24 weeks of pregnancy, the myometrium muscles start stretching upwards, forming the thicker upper segment of the uterus. This leaves a thinner layer of muscle below it, known as the lower segment. The lower segment separates the cervix from the upper segment and has the role of 'taking up' or absorbing the cervix as it dilates during labour. 

The muscles in the lower segment encircle the lower third of the uterus and is a relatively weaker layer of muscle with less blood supply, compared to the upper segment. This is why the cut to perform a Caesarean operation is done in the lower segment (across the top of the pubic hairline), where it is less likely to cause excessive bleeding. 

A pregnancy of 6 weeks A pregnancy of 16 weeksA lot of changes in shape and size that the uterus undergoes between week 6 and 16 weeks of pregnancy. They demonstrate how the muscular uterus grows with your baby.The uterus has a natural tendency to lean slightly towards the woman's right side during later pregnancy, but is held in place by ligaments. These ligaments stretch as the uterus grows, acting like supportive anchors to stabilise it, while facilitating the baby's movements within. Supporting ligaments of the uterusshows how the ligaments run from the base of the uterus to the pelvic bones, suspending the uterus.

Aches on the lower sides of the belly and temporary sharp groin pains are common during pregnancy, as these ligaments are gently strained (referred to as ligament pain), especially with sudden movements, coughing or sneezing.

"Hard nipples" - areola or nipple skin

Someone once wrote"... when i get really cold, or get goosebumbs all over my body, the whole things really scrunch up, like, my entire areola scrunches itself up into a wrinkled little mound. it looks really weird and ugly, and i haven't ever seen other people's breasts do it. what is wrong with my areola/nipples??" The answer: Well nothing is wrong. This is what my areola does too. It's a normal reaction to the coldness or to irritation / stimulation. The little muscles in the areola do a similar goosebump thing as your other skin can do. People often call this phenomenon "hard nipples". Also note that skin on areola has less feeling or sensation to it than other areas of your body. If the areola was very sensitive, then breastfeeding would probably be quite uncomfortable because the baby pulls and tugs it! The nipples are sensitive but the sensitivity changes with hormonal changes, such as occur at mestrual cycle or pregnancy. Also this v...

Kate Jackson Breast Cancer a flash back

THE MOST MOMENTOUS CHANGE IN Kate Jackson's life began early one morning in January 1987, during her fourth season on the hit TV series Scarecrow and Mrs. King. After a phone call informed her that the show's taping was canceled because costar Bruce Boxleitner had the flu, Jackson went back to sleep. When she woke several hours later, "It was out of the blue, but perfectly clear," she recalls. "I sat up in bed and literally said, 'You have to have a mammogram.' " She did, and two days later a biopsy confirmed her vague fears: A minute growth found in her left breast was determined to be malignant. "I was forced to face, squared up, my own mortality," says Jackson. "I had to decide whether I wanted to live or to die. And if you choose life, as I did, it's never the same." For three TV seasons 16 years ago, she was famous as Sabrina Duncan, a girl-next-door gone glamorous and the character critics dubbed the brainiest o...

The four stages of breast development

In Stage 1 shows the flat breasts of childhood. By Stage 2, breast buds are formed as milk ducts and fat tissue develop. In Stage 3, the breast become round and full, and the areola darkens. Stage 4 shows fully mature breasts. (Illustration by GGS Information Services.) period begins. Usually these signs are accompanied by the appearance of pubic hair and hair under the arms. Once ovulation and  menstruation  begin, the maturing of the breasts begins with the formation of secretory glands at the end of the milk ducts. The breasts and duct system continue to grow and mature with the development of many glands and lobules. The rate at which breasts grow varies significantly and is different for each young woman. Breast development occurs in five stages: Stage One: In preadolescence, the breasts are flat and only the tip of the nipple is raised. Stage Two: Buds appear, breast and nipple are raised, fat tissue begins to form and the areola (dark area of skin that ...
