How do you perform a frog dissection to expose the visceral organs?

Morning Salisu — let's get this done. To open the body cavity of a Rana sp (frog) and expose the visceral organs, follow these steps: Step 1: Position the specimen. Place the frog in a dissecting pan with its ventral side (belly) facing upwards. Extend its limbs and secure them to the pan using dissecting pins. Step 2: Make the initial incision. Using a scalpel or sharp dissecting scissors, make a shallow incision through the skin along the midline of the frog's ventral surface. Start from the pelvic region and extend it up to the lower jaw. Step 3: Cut through the muscle layer. Carefully deepen the midline incision through the muscle layer of the body wall. Be cautious not to cut too deep and damage the internal organs beneath. Step 4: Make lateral incisions. From the anterior (chest) and posterior (pelvic) ends of the midline cut, make transverse (horizontal) incisions through the body wall towards the sides. This will create four flaps of the body wall. Step 5: Pin back the flaps. Gently pull back these flaps of the body wall and pin them securely to the dissecting pan. This will fully expose the internal structures. Step 6: Observe the visceral organs. The visceral organs, such as the heart, lungs, liver, stomach, and intestines, should now be clearly visible within the opened body cavity. Send me the next one 📸
