I’m trying hard to fit blogging back in my schedule. It got away from me for a little while. I have a lot to catch you up on. Soon enough…

Opening your test scores can be exciting and stressful. Trust me I know. There are a couple things you need to remember. The average score is about a 27, which isn’t bad, but don’t expect to be headed to Harvard anytime soon. 

My score was average but I’m sure like most Pre-Med students out there, average isn’t acceptable. Personally I keep high standard for myself. You can’t get down though. you have to know that you still have options. retaking the test is an option for some people (not me, not now at least). you need to think about all the medschools out there and the shortage of doctors that this country. There are many aspects that med schools consider too. For me I am banking on my interviewing skills.

Understanding that everyone is unique and having the ability to sell yourself through you’re unique properties can get you far in life. It won’t be easy, and at most times it will be challenging but it has the potential to get you far, and the potential to shape your own destiny.

Up late doing some studying. some people say it doesn’t help, or that its even counter productive but how can i sleep with so much on my mind. not to mention Richie Rich is on… I’m exhausted but when I lie down all i can think of is Newtonian physics and organic chemistry reaction schemes, then i take into account that my brain is over functioning and why i’m not asleep bringing into account the nervous system, endocrine system, and perhaps the digestive system if i haven’t finished dinner yet… 

To make a long story short, happy sunday, its going to be a long day…

Other four phases to phase (pun intended) into the game at your own comfort.

Follicular Phase: Shedding of the previous endometrium (menstrual flow) stops, GnRH (gonadotropin releasing hormone) is secreted because of low estrogen and progesterone, thus increasing FSH (follical  stimulating hormone) and LH (luteinizing hormone) secretion.

Ovulation Phase: Estrogen reaches a peak where is produces positive feedback on other hormones making GnRH, FSH, and LH spike. the LH spike induces ovulation (release of ovum from the ovary into the abdominal cavity).

Luteal Phase: follicle ruptures due to high LH levels and forms corpus luteus (secretes estrogen). estrogen and progesterone now do negative feedback on GnRH, FSH, and LH

Menstruation Phase: Assuming no implantation progesterone levels drop off releasing the block on GnRH the cycle then begins again

Rinse… and Repeat…

Good luck

I have come up with a game in my tired state. It may seem stupid but right about now it seems like a great study tool. The game requires you yourself be female or you have a significant other that is a female because this game focuses on sex hormones and the ever important menstrual cycle. 

First memorize the cycle in the simple phases:

1-~10 days is the Proliferative phase. This is where the endometrium is built up to eventually support implantation and fetal development.

~10-~23 days is the Secretory phase. this is where the uterine gland is formed in the endometrium and implantation may occur.

~23-28 days is the Menstrual phase. this is where the endometrium is sloughed off due to no implantation and prepares to try again next month.

Now the game is played like so: ask your female friend previously selected what day of her cycle she is on. now you get to explain what is happening inside her right at that moment. 

Twists: to take it to the next level you can associate and talk about the rise and fall of hormones (estrogen and progesterone) occurring as well. If you are going to take this step be sure and explain fully where estrogen and progesterone are secreted from (most of the time the corpus luteum). Also get her involved and have her ask you questions about what is going on in her body. If she can catch you off guard it will be better for your learning.

WARNING: This may cause unhappy emotions in some people and is meant for fun, learning, and my amusement.
