August 10th 2009

Hi everyone, I would like to stress again (and boringly, sorry!) that although the cells and tissues Unit is not due to be completed before the end of this week (and the quiz the week after that), I would urge you to complete it as soon as possible so that you can start the Nervous system Unit prior to the practical/tutorial on Friday this week.

You will see that there are two versions of the Nervous system workbook. The first shorter version was one I just uplifted with minor modifications from the Foundation Studies Bioscience course. The second longer one was what I developed when everyone last year told me how short and inadequate the short one was!

I think I have said all I have to say about what we are going to be doing on Friday in last week's Blog so if you missed it please scroll down for a look. As you will see we have a lot to cover in just 2 hours (perhaps longer if you are prepared to stay into lunch). I shall try and give you a general overview of the subject and then we will try and put this knowledge into operation by doing worksheets involving the brain and neuron models and, of course, dissecting the pigs heads.

Looking forward to seeing you all on Friday,

cheers Ruth

Hi everyone, This week you should be looking through the notes on Unit 1 Cells and Tissues. You will see that much of the information on the cell is familiar but slightly more detailed than in Bioscience 1. The usual organelles are there but you are expected to know a bit more about their structures and functions. There are also some new structures including peroxisomes, flagella and cilia and different kinds of filaments and tubules that make up what is known as the cytoskeleton that allows whole cells, organelles and chemicals within cells to move.

The Unit then goes on to describe the structure of the plasma membrane and the various ways in which molecules pass across it. This is the part of the unit that has most new information as it describes the functions of the various different proteins in the plasma membrane. You will learn that diffusion can occur through the phospholipid bilayer, through protein channels and through gated protein channels, and that active transport can be aided by transporter proteins, co transporters or counter transporters. You will learn how receptor mediated endocytosis differs from pinocytosis and in the interactive version of the Unit one of the revision excercises asks you to match the molecule with its mode of entry into the cell.

Two other new topics in this Unit are the cell cycle and the different stages involved in normal cell divion or Mitosis. Finally the section on tissues should be pretty familiar although a few new tissues are described --pseudostratified columnar epithelium for example-- and the structures and functions of the tissues are described in slightly greater detail.

It would be great if you could get this Unit completed this week so that you can start on Unit 2, the nervous system, next week. This will allow you to come to the tutorial/practical on Friday Aug 14th with some knowledge of this system. Here I can talk about the basic structure of the neuron and the central and peripheral nervous systems but it would also be good if you can apply some of the knowledge by doing excercises that involve recognising structures on models of the nerve cell or neuron and the human brain. I have also ordered some pigs heads which have been cut in half to reveal the brain so you can observe and dissect these. Looking at a real brain and recognising the different areas and structures is a wonderful learning opportunity that is definateley enhanced by a bit of prior knowledge.

Have a good week,

Cheers Ruith

July 27th 2009

Hi everyone, Not much to say this week except I hope you have all got on to Blackboard OK, had a look at the Bioscience 2 timetable and generally cruised around the site.

I was pleased to see everyone on Tuesday. For those that didn't make it we talked about the course and in particular the timetable. I pointed out that the first few weeks are mainly revision although do watch out as there are a few new topics and facts. This means that it would be a really smart to get ahead of the timetable so you have a bit of extra time to do those topics that are new. In particular the nervous system is a mountain to be climbed, with 3 separate parts to the notes and then the endocrine and digestive systems come close up behind with lots of new concepts and terms.

Oh yes, the main discussion point was tutorials. We talked about Elluminate versus face to face sessions and the general concensus was that face to face was more profitable. We decided to provisionally book one for 10-12am on Sept 16th on the Digestive System and then to see how you go and book more if needed. Those that may having trouble getting to one in the middle of the week please speak up. Please email your comments on this so I get all the feedback I can.

I have now worked out all your final marks for Bioscience 1. If you haven't received an email telling you yours tell me and I will resend it.
cheers Ruth

July 20th 2009

Welcome to the second semester and Bioscience 2.

I have just given you access to this course on Blackboard (I hope) where you will find the timetable for the semester, the assessment schedule, the notes and the quizzes. Have a look around and see what you will be covering from now till the end of November.

You will see that the format is pretty similar to that of the first semester and some of the topics will even look familiar. However, Bioscience 2 is one level up on Bioscience 1 so you will covering things in more depth and be you will be expected to understand it to a greater degree as well as apply the knowledge and intergrate it with what you have already learnt to a greater extent.

Just note that the first two topics are really revision and Unit 1 on cells and tissues is really what you have already done but with a few new things added, so you should be able to whizz through them. Then timetabled to start on 17th August is the Nervous system. This is a bit of a shock as it is A BIG UNIT! By big I mean the notes are in 3 parts and you will find much of it is new with an awful lot of new terms. Do not underestimate it. So I am suggesting that it might be a good idea to get ahead of yourself and perhaps start working on this unit before suggested by the timetable. To enable you to do this I have put up the quizzes for all the units from the first day of term. You still need to keep an eye on the closing dates as, like last semester, they will close a week after it says on the timetable.

Looking forward to a great semester and also to seeing you on Tuesday (July 21st) morning,

Good luck,
Ruth

November 17th

Just 11 days to go before the final test - sorry to remind you!

You should by now be well into the last unit, The Urinary System. You should have worked your way through the workbook and have done the quiz so that you have time to look at the other units, especially the Immune and Respiratory Systems, that have not yet been tested in a test.

Last week we had a very sucessful 2 hour tutorial on the cell, respiration and the urinary system. This week's tutorial will be on the nervous and endocrine systems. Please come along if you can.

I gave the details of the format of the test and the mark allocation in the previous blog.

Good studying,

Ruth

Bioscience 2. November 11th

Hi, This week you should be finishing off Unit 7 on the respiratory system (after doing the online quiz which closes next Monday) and moving on to Unit 8 on the excretory system. THE LAST UNIT!

In the practical last week we dissected (New World) kidneys and I talked about the function of the kidneys. I intend to do more on the kidneys at the tutorial if that is what people want. I shall also talk about the respiratory system and --since we have 2 hours - I could go back to the beginning and revise Cells and Tissues.

The format of the exam will be similar to the final exam in Bioscience 1, although there is more material to test so there will be fewer marks for each unit. There will be 2 longer questions out of a choice of 8 worth 5 marks each at the end of the paper and the rest of the 90 marks will be distributed between the 8 units studied. However, I will only allocate 6 marks to the first unit as that was covered in quite a lot of detail in Bioscience 1. This leaves 12 marks for each of the other 7 units.

Please remember if there is something you dont understand about the course material as you study for the exam or about the format of the exam dont hesitate to drop me an email and I will endeavour to clarify for you.

Have a good week,

Ruth

November 3rd

Hi there, You should have all moved on to studying the Respiratory System by now and have another week until you move on to the final unit- the Urinary System.

The Blackboard quiz for the immune system closes tonight, so if you haven't done it yet you will need to get your skates on!

We had a good tutorial last week which focussed mainly on the immune system. We developed our own concept map on the whiteboard and whizzed through the immune system Powerpoint I have put on Blackboard. Have a look at it as I think it simplifies this rather complex topic and emphasises the points that are important. At the end of the presentation there is also a simplified version of the concept map we developed.

For those that want to get ahead of things before the Test on November 28th I have put up the interactive and printable notes for the final unit: the Urinary System. I am working on the quiz and should get that up before Wednesday and the workbook will follow.

In the practical class on Friday we will be looking at and cutting into kidneys and then I will spend the rest of the session talking about the kidney and kidney tubule structure and how urine is formed using the polytechs great models.

Finally the test will be a longer version of tests you have already done and will cover all the 8 units studied this semester. (Not the same questions though! Sorry!) Make sure you use the workbooks in your revision as they will be very useful, but also look back over the BB quizzes and of course the interactive notes and the questions that pop up there.

If you find there is something you dont understand as you go back over the material, dont hestitate to send me an email or even phone me on 4748497 as I will be at my desk most afternoons and am always happy to help.

Have a great week,
cheers Ruth
