Eyes, ears and potassium
Monday's gross anatomy was on the eye and ear. We swapped around between dissecting eyeballs, using ophthalmascopes, using oroscopes, looking at the prosected heads, and looking at skulls. Then in the afternoon we had a clinical lecture on eye disorders. There were some gory pictures of knives and pens in people's eyes and some optical illusions as well as the theory on visual disorders.
Yesterday we had two virology lectures with our tutor, Dr James, and then a tutorial with him in the evening. The lectures were on influenza and the PBL tutorial was on immunity. I'm just researching it now! It's not a clinical one, like they usually are. It's on an experiment where various immune cells from mice after infection are cloned and injected into other mice with varying characteristics. As well as predicting the results of the experiment we have picked out some aspects to look into a bit more detail on, for example the secreted product INF and the experimental technique FACS. We also had a pharmacology seminar yesterday. It was about synaptic pharmacology, particularly in the central nervous system. Although there were a lot of drug names, some of them and many of the conditions they are used to treat were familiar, so it was interesting.
Today we had a lecture on sound and the ear, which went over a lot of the same information that was in an essay I have just written, and a lecture on regulation of potassium in the body. Did you know the potassium in your blood goes up to such high levels during exercise that the same levels at rest would stop your heart? (other chemicals counteract the dangerous effect) And it's potassium ions, not lactic acid like you're told at school, that makes your muscles hurt during strenuous exercise - people who can't make lactic acid still get the same pain.
