Ovulation - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: Ovulation is a part of the menstrual cycle when the ovary releases a ripe egg, or ovum. Inside the ovary are hundreds of thousands of follicles. Each follicle is a hollow ball of cells with an immature egg in the center. The typical 28 day menstrual cycle begins on the first day of menstrual bleeding. During the first seven days of the cycle, a few follicles begin to grow at the same time. These maturing follicles secrete estrogen hormone into the bloodstream to prepare the lining of the uterus for pregnancy. Around day seven, all of the follicles stop growing and begin to generate, except for one. This dominant follicle continues to grow and nourishes the developing egg inside it. Around day 12, the follicle secretes a large amount of estrogen into the bloodstream. When the estrogen reaches the hypothalamus and pituitary gland in the brain, the anterior, or front part of the pituitary gland, releases a huge surge of luteinizing hormone into the bloodstream. Around day 14, luteinizing hormone causes the follicle to undergo a sudden growth spurt. Right before ovulation, the egg detaches from the inside of the follicle. The bulging follicle releases chemicals, causing one of the two fallopian tubes to move in closer and surround the follicle. The follicle swells until it bursts open, ejecting the egg and fluid from the follicle into the abdominal cavity. In response the fimbriae, tiny projections at the end of the fallopian tube, sweep across the ovulation site and pick up the egg. Microscopic cilia on the fimbriae surface, transport the egg to the entrance of the fallopian tube. Inside the walls of the fallopian tube, muscular contractions gently push the egg towards the uterus. After ovulation, the egg lives for 12 to 24 hours, so it must be fertilized by a sperm from the male during this time for a woman to become pregnant. If it's not fertilized, the egg dissolves away and is shed along with the uterine lining during menstruation.

What attorneys say about MLA and The Doe Report:
"The Doe Report is a visual feast of medical information for personal injury lawyers."

Aaron R. Larson, Esq.
President
ExpertLaw.com

"It is with great enthusiasm that I recommend Medical Legal Art. We have used their services for three years and always found their professionalism, quality of work, and timely attention to detail to exceed our expectations. We recently settled two complicated catastrophic injury cases. One medical malpractice case involving a spinal abscess settled for 3.75 million and the other involving injuries related to a motor vehicle accident settled for 6.9 million. We consider the artwork provided by MLA to have been invaluable in helping us to successfully conclude these cases.

I highly recommend MLA to anyone seeking high quality, detailed medical legal artwork."

"The illustrations have consistently been well documented, accurate and timely. Most important though is that the illustrations demonstrate to juries and claims people the persuasive power of visual communication. Our firm has achieved multiple eight figure settlements and verdicts over the past ten years... Medical Legal Art has been there with us on every case."

"Thank you for the splendid medical-legal art work you did for us in the case of a young girl who was blinded by a bb pellet. As a result of your graphic illustrations of this tragic injury, we were able to persuade the insurance company to increase their initial offer of $75,000.00 to $475,000.00, just short of their policy limits.

We simply wanted you to know how pleased we were with your work which, to repeat, was of superlative character, and to let you know that we would be more than willing to serve as a reference in case you ever need one. Many thanks for an extraordinary and dramatic depiction of a very serious injury which clearly "catapulted" the insurance company's offer to a "full and fair" amount to settle this case."
