Start of week 8, now I am getting really nervous about being able to raise enough money to allow me to continue in vet school next semester. Towards the end of term things are going to get more busy and my workload is going increase with more credit tests and preparation for my final exams in December and January. I really do need to find as many advertisers monthly sponsors in the next two weeks as I possibly can so I do apologise in advance for the crazy amount of tweets asking for help!

Anyways onto today, this morning when I woke up it was pouring with rain, not just a little but absolutely torrential. On the way back to dorms glancing at the stream that is between uni and the dorms which is usually a foot wide trickle I was pretty shocked to see raging waters…
Anyways back to my veterinary education as thats why you are here :p This morning was Histology where we looked at the different types of nerve cells, how they worked and their structure. Looking at nervous tissues cells can be broken down into neurones and glial cells, and glial cells broken down further in CNS (Central Nervous System) or PNS (Peripheral Nervous System) cells. Its amazing how much detail can be seen just with a lightmicroscope when you understand completely what you are looking for and more importantly looking at. Take for example a astrocyte
The astrocyte is the most numerous type of glial cell in the central nervous system (CNS) and contribute to the blood-brain barrier .which controls the flow of blood carried molecules to the brain tissue. Their processes (long strands from the main body) have feet which attach to blood vessels with the other side attaching to neurons. In addition they also store glycogen and release glucose which is used by cells for energy production.
Today I also did the resit for the Histology theory paper that I originally failed as I revised the wrong things. This time I did pass with a C which I was pretty pleased with as I knew I got 2 questions wrong as I keep getting the functions of the Rough Endoplastic Reticulum and the Golgi Aparatus back to front… Actually I wrote it the correct way round and then rubbed out the answer to switch it around (oooopss). Anyway onto the next one which will be next Monday and on everything we have covered since.
This afternoon was the Physiology lecture, today we had a specialised in the urinary system in as a guest lecturer which was pretty cool. For one of the smaller organs in the body the Kidney could said to be one of the most complicated. It has the function of removing waste products from the blood, and does this by either filtration or secretion. The most amazing thing I think I learnt here is that less than 1% of the volume that passes through the kidney is actually removed from the blood for excretion from the body. The kidneys deserve a post to themselves which they will be getting very shortly!
Until tommorow people 🙂Posted in categories: Vet School Diary
