| Objective |
In this event teams of 3 to 6 will be expected to develop careful dissection
techniques and become familiar with the name and location of the major structures
of the circulatory, respiratory, digestive, and urogenital systems as described
in the dissection guide to be provided. Students will be allowed to open up the
thoracic and abdominal cavities, identify structures (approximately 15) and complete
a dissection questionnaire regarding structure, function and physiology of organs |
| Purpose | Explore
the biology of the foetal pig. |
| Participants | Teams
of up to six. Only one team per school may enter this event. |
| Materials | Non-dissected
male and female specimens will be provided on the day of competition. These are
obtained from a Scientific Supply Company. Students must bring to the competition
their own dissecting kit and gloves, and a pen or pencil for answering the question
sheets.. Each kit may include 1 scalpel, 1 spare scalpel blade, 1 probe, 1 pair
of tweezers, 1 pair of dissecting scissors, and 1 box of T-pins. |

Sample Directions 1. Insert a green pin into the gall bladder.
2.
Insert a red pin in the organ which is the site of sperm production.
3. Clear
the tissue from the region anterior to the heart and insert a black pin in the
right subclavian artery
.4. Name the tube that drains the bladder. Each
year, a particular system will be designed for special study, and this will be
announced on the web page.
(i) Each dissection will be marked out of 100%.
Structures must be clearly displayed.
(ii) Written answers to questions
will be marked out of 100%.
(iii) The final mark will be calculated using
the following weighting: 65% dissection (i above) and 30% questions (ii above),
plus 5% if you bring your own dissection kit and gloves,
to give a total mark out of 100%. |
