Selam! I just found out ths article from
kevinmd.com, a very useful website for young doctors out there. Have a read :)
By far one of the most unique experiences
first-year medical students can have is working in the gross anatomy lab. From
the potent smell of formaldehyde to the chill of the ventilation, the anatomy
lab provides a visceral experience that is hard to forget. The thought that the
cadavers on display were once living beings and are now about to be dissected
can overwhelm even the most stoic student. Human anatomy is hard enough to
learn when displayed neatly in a book, but combining it with a cadaver can
unsettle anyone. What’s a first-year medical student to do? Should she spend
every available minute in the lab? Or should she just learn anatomy from a book
and hope everything will look the same on the practical examination?
The best way to learn anatomy is using both
methods — dissecting cadavers and studying the book. The least efficient way to
do this is to simply show up in the anatomy lab unprepared. To avoid wasting
time, you need to enter the anatomy lab with a plan. If you don’t know what
you’re looking for, you can waste countless hours in the lab looking at
pictures and hoping you don’t cut something vital. If you’re already familiar
with the anatomy you’re trying to learn, both the dissection and identification
will proceed more quickly and smoothly. Learning the anatomy from a neatly
displayed and labeled anatomy text takes less time initially than does learning
on a messy, unlabeled cadaver. Thus, the most efficient way to approach the
anatomy lab is to first learn what the anatomy is supposed to look like by
studying textbooks or lecture slides. Once you know what things are supposed to
look like, you’ll have an easier time recognizing those parts in the cadaver.
Most medical students usually ask what kind of time they need to spend in the
lab. Some students seem to practically sleep there, while others seldom show
up. We’ve already established that those who have studied and are familiar with
what the anatomy is supposed to look like will spend less time in the lab. But
suppose you already know the anatomy reasonably well. How much time should you
spend with the cadaver, considering that you will be responsible for knowing a
long list of items? Some of these are easy to find (large muscle groups), while
others are damn near impossible to find (small nerves). Of course, every
cadaver is slightly different, so while one muscle may be hard to find in one
cadaver, it could be easy to find in another. For this reason, it’s wise to make
every effort to examine a few cadavers. Know that some items are almost
impossible to find no matter which body you choose to examine. Many medical
students end up spending large amounts of time looking for
almost-impossible-to-find structures such as the thoracic duct. The question
becomes whether you should spend extra time trying to identify every single
structure.
Not surprisingly, the principle of diminishing
returns applies here as well. If you wish to find every item on every list,
you’ll spend most of your time searching for the harder-to-find items. Think of
this as searching for the proverbial needle in a haystack. Suppose you really
want to find the ligamentum teres and decide that you won’t leave the lab until
you’ve found it. You might end up spending a half hour searching multiple
bodies before you finally identify this structure. You need to ask yourself if
the discovery of the ligamentum teres is worth half an hour of your time. For
those bent on achieving a perfect score, the answer is yes. For most other
medical students, the answer is no. If you know the anatomy well, you can
assume that the harder an item is for you to find, the harder it is to find for
the faculty as well. This doesn’t mean the ligamentum teres, for example, won’t
show up on a practical exam; it just means that it has a lower probability of
showing up. In my experience, having studied anatomy thoroughly, when I was
unable to find an item on an already-dissected cadaver in under a minute, it
seldom showed up on the exam.
