Please note that one half of your final grade in the course will be based on the grades in the two hour examinations and the final examination, and that the other half of the final grade will be based on the grades in the laboratory examinations and your laboratory work. If the grade in either the first hour examination or the first laboratory examination is significantly lower that those in the other examinations, then that grade will be largely, but not completely, discounted in assigning the final grade in the course. Note that this does not mean that your lowest examination grade will be dropped, only that a poor grade in one of the two first examinations will be largely discounted if the rest of your grades are significantly better.

 

You will not be required to keep any written notes or drawings of your dissections, but you are free to do either or both if they assist in your learning.

FINAL PRACTICAL EXAMINATION: Tuesday, 6 May , 2004; PM (Time to be announced)

 

Please note that your dissections will be graded two times during the term, about the times of the midterm examination and of the final examination.

 

Laboratory Manual: D.G. Homberger and W.F. Walker, Vertebrate Dissection, 9th Edition [page references in square brackets are to the 8th edition]. Read the indicated pages in the laboratory dissection guide before each laboratory.

 

Urge that you also read the corresponding chapters in Walker's Functional Anatomy of the Vertebrates before each laboratory. This is most important for completion of the laboratory work in the time assigned.

 

Dates for Laboratory Examinations are absolutely firm. No make‑ups are possible

Please note that the first laboratory examination is before the Spring Holidays, and hence that you will not have this period to study for it.

 

Laboratory Materials needed for Biology W3002Y

Materials needed for dissection (Do not purchase these until you are provided with additional information in the laboratory):

1 pair of scissors ‑ heavy

1 pair of fine point scissors (make sure points meet)

1 scalpel with removable blade

2 dozen blades (assorted)

1 probe

1 pair of strong forceps

 

Do not get scalpels with a fixed blade. They are difficult to sharpen and will not hold a good edge. The best quality instruments are stainless steel. These will not rust and you will be able to use them for years. The next best are nickel plated and then chrome plated. We suggest that you do not get your dissecting instruments until the first laboratory period when the TA will discuss what is needed and suggest where they may be purchased. The instruments can be purchased from any surgical supply house. Plastic gloves can also be purchased from the surgical supply house. A heavy lanolin creme works better than gloves.

 

Unfortunately we cannot provide a locked drawer in the laboratory so that you will not be able to store your laboratory materials there, and will have to take them with you and bring them each time you work in the lab. You will be provided with a key to the laboratory so that you can work there on your own whenever the building is opened, including weekends.
