Asperger Syndrome

I was talking with a friend this week about Asperger Syndrome, and she peaked my interest in the cause of the disease. The main cause of the disease is linked to neural activity, although genetics may also play a part. In Asperger patients, there is an abnormal migration of embryonic cells during fetal development that affects brain structure. This, in turn, affects the neural circuits that control thought and behavior. The genetic component of this disease has not yet been linked to a specific gene, however scientists have determined that the disease runs in families. Asperger patients are usually identified by their lack of judgment, unusual facial expressions and repetitive behavior. Overall, they are most affected socially, although adults can lead relatively independent lives. I immediately thought about the chapter in our textbook about nerve tissue and how something as small as a thinning myelin sheath on an axon can have disastrous effects on an individual. As proved by this disease, even neurological abnormalities during fetal development can have lifelong effects.

Fordyce Spots

This week in class, we were talking about the first part of digestion. One term that was new to me was Fordyce spots. These are modified sebaceous glands that are not associated with hair follicles, and yet, are found in the submucosa just lateral to the corner of the mouth and in the cheeks opposite the molar teeth. This was a new term to me because I assumed that all sebaceous glands were equal. It was new for me, not only to learn that these are really sebaceous glands, but also that these spots are visible to the eye. It's interesting that these are visible when they are found in the submucosa layer.

So we had our third exam today, and I must say I felt more confident on previous exams. This is good because I'm not only learning new subject material, but I'm able to teach myself a new way to learn material. Last week, I commented on how I thought exams and quizzes were my weakest point, but this week, I had a big change of heart. I spread out my studying time instead of studying for multiple hours at once. For some reason, it made a huge difference and I was able to retain the information for longer, in almost as much detail as I studied it in. Although I still think this area is my weakest area in this class, I feel like I have gotten much stronger in it. The other point that I was commenting on in my last post was about how I needed to make labs more fun for everyone. I am happy to report that we have formed a good group at the back right of the classroom. We have all finally gotten comfortable with each other enough to have fun while we complete our work. The funny thing is that none of us really knew each other before this class, and now we've all become friends. I always thought of myself as a shy person and I usually don't strike up conversations with everyone I meet, but for some reason, I've been able to come out of my shell in this class and accomplish my goal of making some noise in class.  : )

Reflection

Overall, I have come to enjoy Histology class. At the beginning of the class, I have to admit that I was skeptical about the interest I would have doing microscope work for 16 week straight. Now, however, I am at ease using the microscope. It seems like second nature. Even while doing drawings during lab, I feel as though I am more perceptive about the little details (that actually matter in this class). I find myself looking for them, and identifying other layers and structures in lab to help myself remember what they are (i. e. blood vessels or connective tissue) and how they look in different tissues. The hardest part of this class for me are still quizzes and exams. I'm not sure if I freeze up or if I just need more practice identifying specific tissue characteristics. Hopefully, this is something that will be fixed in the near future, especially as the end of the semester is drawing near. The only thing I really feel like I need to work on is talking. Our labs are still extremely quiet, and I just need to step up and make them more fun for everyone. : )
