We will be doing two dissection labs in Regents Biology --
Flower and Fetal Pig. Students must complete at least one dissection as
part of the regents lab requirement.
We usually do the flower dissection in February (following
reproduction) and the Pig Dissection in late May/early June (following human
body systems).
Dissection Safety
Proper safety procedures when
working with dissection tools and specimens is of greatest importance.
Some safety rules to engage in when dissecting specimens are as follows.
|
Dissection Safety Rules
|
- Follow all instructions given by your
teacher.
- Inform your teacher of any illness as a
result of exposure to chemicals used in specimen preparation.
- Avoid contact with preservative chemicals.
Rinse the specimens completely before dissection.
- Know where the eye-wash fountain is if needed
(35 prep room).
- Wear safety goggles to prevent the
splashing of any chemicals into the eyes.
- Properly mount dissection specimens to
dissecting pan. Do not dissect a specimen while holding it.
- Handle scalpel or razor blade (safety edged)
with extreme care.
- Always cut away from your body and
away from others.
- Never ingest specimen parts.
- Never remove specimens or specimen parts from
the classroom -- until the dissection is completed all parts of
the dissection must remain within the dissecting pan.
- Properly dispose of dissected materials.
- Store specimens in as directed by your
teacher.
- Clean up the work area and return all
equipment to the proper place when the dissection is completed.
- Wash hands after each dissection.

The pictured dissection equipment from left to

used to pull apart muscle tissue, (2) dissecting scissors
which are used to cut through tissue, and (3) a scalpel,
which is a knife used to slice through and cut tissue. |
