Practical Exam I Please do not touch or point at bones, plastinized parts, or models with pens or
pencils - use only broom straws or wooden cotton swabs.
Human Plastinates: These are human tissues. Please treat these specimens with respect and care. You must sign specimens in/out. Only handle them while wearing non-latex gloves. Keep pens and pencils far away. Be gentle.
Identifying Bones: Bones will either be articulated or disarticulated. You should be able to identify these bones in either state.
o Bones Boxes: Make sure you have the correct bones in the boxes before you leave lab.
Muscles: Anatomy and Physiology Revealed [APR]– all the muscles can be
visualized in APR, and you will need to identify the muscles on the models, plastinated specimens, and in APR. The sooner you use APR while learning this material, the easier the material will become.
You are responsible for recognizing all the bolded functions in the muscles; these functions are taken from APR and may be slightly different from what Saladin lists.
APR shows the written function and has animations of those functions for most of the muscles on the lists.
Histologyo The slides will be shown in lab and there are also references to APR where
you can also review the histology. It is recommended that you review the histological specimens not only on APR, but also the web. This can be done by using keywords and any of the popular web-browsers.
