Fetal circulation: three shunts, one rule
Hearts are pretty cool, and so are developing fetuses. Unfortunately for the student preparing for the MCAT, they’re also both pretty complicated, and fetal circulation differs from adult circulation in three main structures. In the next couple paragraphs, I’m going to break down these structures with one rule. If you’re not familiar with adult ...
Hormones of the female reproductive system
The female reproductive system can at times feel like a difficult jumble of hormones that all seem to be related, but fluctuate in unpredictable ways. To make sense of the particularities of the female reproductive system, especially for exams like the MCAT, it is important to not only know what hormones are involved, but also to understand what ...
Gametogenesis and spermatogenesis and oogenesis, oh my!
Meiosis is one of those processes that we all learned about in high school biology as a deceptively simple concept. You take the diploid cell, divide it twice, and it becomes four haploid gametes that are each capable of participating in fertilization. Easy, right?
Pituitary gland hormones made simple
What is the pituitary gland? Even though the pituitary gland is about the size of a pea, it plays a very important role in regulating a lot of our body’s endocrine functions. Located in an area known as the sella turcica at the base of the brain and suspended from the hypothalamus by a stalk, the pituitary gland consists of two parts: the ...
Essential tips for learning the anterior pituitary hormones
Learning the anterior pituitary hormones for your biology class or the MCAT can be a little overwhelming. It is easy to get lost in the weeds and struggle to see how it all connects. One thing that helped me when I was learning the anterior pituitary hormones was to visualize the connections between the most important structures. This both helped ...
Enzyme inhibition and Lineweaver-Burk plots: MCAT test prep
We’ve already covered a little bit about the basics of enzyme kinetics,  so now let’s move on to discuss an important application of enzyme kinetics in the body (and in medicine)...
