Frog Dissection Techniques and Concepts

The video tutorial guides viewers through a frog dissection, starting with the removal of the skin and initial incisions to open the body cavity. It continues with cutting through the abdominal muscles to expose internal organs, removing fat bodies for better visibility, and finally extending cuts to reveal the heart. The instructor provides step-by-step instructions, highlighting key anatomical structures such as the liver, stomach, and heart, and offers tips for effective dissection.

What is the first tool you should use to start the dissection of the frog?

• A scalpel or scissors

• A hammer

• A needle

• A tweezer

Where should the initial cut be made on the frog?

• At the tip of the mouth

• Along the midline

• Across the legs

• On the back

What is the purpose of creating flaps during the dissection?

• To clean the frog

• To remove the bones

• To make the frog look better

• To expose the internal organs

What should be done after exposing the abdominal muscles?

• Cut through the muscles

• Remove the skin

• Cut through the bone

• Sew the frog back up

Why is it important to remove the fat bodies during the dissection?

• To make the frog look cleaner

• To prevent contamination

• To see the internal structures better

• To make the frog lighter

What structures become more visible after removing the fat bodies?

• The legs and arms

• The eyes and mouth

• The liver and stomach

• The bones and skin

What is the final organ exposed during the dissection?

• The stomach

• The lungs

• The heart

• The liver

What must be cut through to expose the heart?

• The liver

• The stomach

• The skin

• The bone

What is the pericardium?

• A part of the liver

• A type of muscle

• A covering of the heart

• A bone in the leg

What can be done to further expose the heart after cutting through the bone?

• Remove the skin

• Tear the pericardium

• Cut the liver

• Remove the stomach
