    Today is the last day of lessons this week as tommorow is a Rectors day (a day off agreed by the Rector of the university) for the Matriculation Ceremony. Being Thursday I have Anatomy and Physiology today with an exam on the skull, in addition I spent last night revising so have not had the chance to sleep. Pretty bouncy from so much caffiene as well so all in all going be pretty interesting today.

    Today started with the anatomy lecture which went over the structures of the skull again, for something that I’ve just thought of as the container for the brain its pretty amazing how many different parts it has. The skull is not actually a single bone but a collection of different bones all fused together.

    It was then onto the Physiology practical, today was following the cardiovascular (heart and circulation) theme and we started looking at ECG’s and actually understanding what they actually mean in relation to the contraction of the heart. So we had a demonstration of the taking of the ECG on a dog, and were then given a copy of the results to work from.

The different leads show the potential differences at different parts of the body, and from this using Einthovens triangle we can even work out the position of the heart with the chest cavity (now how cool is that!!!). When looking at an ECG the first peak is the depolarisation of the artriums (the smaller chambers of the heart) before the big peak being the depolarisation of the ventricles which are the larger chambers of the heart.

    So its finally time for anatomy and I am confident on my internal structures of the skull, as well as the common landmarks. The first question was like a slap across the face, I remembered reading about it, I just couldn’t remember what the hole was that the tweezers were pointing at… Moving on I named every process and bone until again we come back to another hole… And my mind stays blank. I knew the horse inside out, I even knew the dog, this cow skull in front of me however was a nightmare. Every species has differences, sometimes subtle, sometimes obvious. Instead of having a single large opening like the foramen lacerum in the horse which is split into different sections the cow has 3 completely seperate openings. I ended today with a C… If it had been a horse I would have scored much higher….

    And then to add insult to injury, the practical session was based on all the internal structures I had spent so long learning for next weeks test… Looks like I should be back to an A next week! Anways after Anatomy this evening I walked to Tesco Hyper with a friend as I needed to get my suit dry cleaned for tommorow.
