Menstrual Cycle

This is my attempt in explaining the menstrual cycle. I decided to write about this since I must learn all of it for my future job.



It all starts with the Pituitary glands, they  secrete a hormone that flows through the blood stream and reaches the ovaries, creating a follicular cyst, surrounded by eggs and secreting hormones. Then the pituitary gland secretes another hormone called the LH(Luteal Hormone). There is a peak of the hormone level that will release the egg. The egg is then sucked in by the fallopian outer edge. It takes 5-6 days for the egg to travel to get to the uterus. Back to the over, after the follicle has ruptured out of it, it is converted into this yellowish body called the corpus luteum. Cells of the corpus luteum secrete the hormone called progesterone, which bring about important changes to the lining of the endometrium making it suitable for fertilized egg. If there is no fertilized egg then the endometrium lining will shed causing the menstrual bleeding.

Transducer

Today I will explain to you how a transducer works.

For a Sonogram exam the technician uses a device called a transudcer this transducer emits pulse waves into the body. Inside the transducer there is a part called the "backing material" this backing material holds back the electricity that is coming in from the wire, then it is released and hits the crystals and causes a phenomenon called the piezoelectric effect which then emits a pulse into the body as a sound wave. Before entering the body it must pass through the matching layer which is placed infront of the crystals.The purpose of the matching layer is to try to maximize transmission of ultrasound from the crystals to the patient. Once the sound wave has reached a boundary it will return to the transducer and it will be converted back into electric energy then it will form an image.

And back.

Ive been preparing myself for the physics exam. Once I get to chapter 15 which will be after two classes I have to sign up for the exam online. I can not wait I feel as if I know so much more now thanks to the tutoring that I can't wait to sit for the exam. The exam will have 120 questions. I like to practice at home with this physics program I have called "Davies" it is very good and helps me a lot. I take quizes and see how I've  progressed. EXCITED! I need to be working as a tech before 25 that is my goal!! woo lets get it!
