Fetal Pig Dissection Procedures

In this video, the instructor demonstrates how to dissect a fetal pig, starting with preparation and stabilization of the specimen. The process involves making careful incisions to expose the muscles and organs without causing damage. The video covers opening the abdominal and thoracic cavities, highlighting the importance of preserving the diaphragm and examining key structures like the trachea and thyroid. The session concludes with a preview of the next video, which will focus on identifying and understanding the organs listed in the lab manual.

What is the first step in preparing the fetal pig for dissection?

• Identify the organs in the manual.

• Tie back the four legs and stabilize the pig.

• Make an incision in the abdomen.

• Remove the umbilical cord.

Why is it important to avoid damaging the organs during the initial incision?

• To ensure the organs are visible for study.

• To prevent the pig from moving.

• To make the dissection faster.

• To avoid the release of preservatives.

What should you keep handy to manage the preservatives during the dissection?

• A scalpel

• Scissors

• A lab manual

• Paper towels

What is the recommended action if you feel unwell during the dissection?

• Step back and let a partner continue.

• Continue working quickly.

• Leave the lab immediately.

• Stop the dissection entirely.

What tool can be used to cut through the muscles and skin?

• A ruler

• A hammer

• Scissors

• A pencil

What is the purpose of opening the thoracic cavity?

• To access the abdominal cavity.

• To remove the diaphragm.

• To examine the lungs and heart.

• To stabilize the pig.

What is the main focus when opening the thoracic cavity?

• Removing the rib cage

• Identifying the stomach

• Measuring the diaphragm

• Avoiding damage to the organs

What is the significance of the diaphragm in the dissection?

• It is the easiest part to dissect.

• It contains the most preservatives.

• It is the largest organ in the body.

• It separates the thoracic and abdominal cavities.

Which structures are examined in the neck area during the dissection?

• Trachea, thyroid, and thymus

• Kidneys and intestines

• Heart and lungs

• Liver and stomach

What should you do if you encounter difficulty in the neck area?

• Skip the neck area entirely.

• Ask the instructor to do it for you.

• Use more force to cut through.

• Be gentle and proceed carefully.
