Do this between the rear legs of the frog.ģ. You will find it easier to begin the vertical incision by lifting the muscle layer with the forceps. Repeat the incisions, this time through the abdominal muscle.

Use a scalpel to help separate the skin from the muscle layer below.Īfter you've opened the flaps of skin, pin them to the dissection tray.ġ. Pick up the flap of skin with the forceps.ġ0. Be careful to only cut through the skin, not the muscle.ĩ. The first incisions are made between the front legs. Use the scissors to make sideways incisions in the skin. Stop cutting when your scissors reach the frogs neck. Use the scissors to continue the incision up to the midline all the way through the frogs skin. This is a starting place for the scissors. Make a small cut through the lifted skin with the scalpel. Lift the frogs skin with forceps between the rear legs.3. Place your frog on its back and pin it to the dissecting tray.2. If you are unsure of the directions, ask!

This is where the real dissection begins. Find the esophagus at the rear of the mouth. It is a slit opening for the voice box on the floor of the mouth.ĥ. Notice that only the upper jaw has teeth.Ĥ. Feel the maxillary teeththat are along the rim of the upper jaw. Use the scissors to cut the corner of the mouth where the maxilla (upper jaw) and mandible (lower jaw) join together.ģ. Determine if your frog is male or female by looking at the innermost finger of the forelimb.ġ. Find the digits, which are like fingers on both the fore and hind limbsĦ. Identify the tympanic membrane, or eardrum. Identify the eyes, which have a nictitating membrane that serves to moisten the eye.ģ. Make sure frog is right side up so that you can see the face.Ģ. Turns! When you are ready to begin, look forward and be silent. Decide who will start the dissection, remember to alternate Partner 1 get tray, frog Partner 2 get instruments and paper towel Both partners lay out supplies at their lab table, placing the Preparation: Tie hair back, put on apron if you desire and get a pair of Getting ReadyMaterials: Gloves Dissecting tray Preserved frog Forceps Scalpel Dissecting scissors Hand lens Probe Dissecting pins

Conclusion questions will be individual work. After the dissection is completed, share your observations so that both people have a completed lab report. If you are the person dissecting, then the other person in the pair is assisting. Pick one person to start and then alternate.

To observe the relationship between organ structure andįunction. Purpose and TermsPurpose: Investigate the anatomy and organ systems of the frog. Your scissors are your most important tool, but be sure to handle them carefully and always double check instructions before cutting. Take extra care with your dissection tools. While dissecting, be respectful of your lab partners and of the specimen you are about to explore, observe and learn from. You will also face disciplinary action and MY WRATH!!!! If at ANY time, I feel that your behavior is inappropriate you will be asked to stop the lab. You are expected to behave appropriately in this lab setting. al.Dissection does not mean to cut up, it actually means to expose to view A Comparison of V-Frog to Physical Frog Dissection, James Lalley et.V-Frog White Paper (PDF) V-Frog featured in The Wall Street Journal articleĬoming Soon To Schools: Dissecting Frogs in 3-D (September 7, 2011) V-Frog™ Shines in Academic Studies To read a white paper on V-Frog, click the link below. 3D Stereo (Cardboard, Shutter, and Polarized): Contact us for hardware requirements.Additional Species (Flatworm, Sponge, and Jellyfish).Dissection (cut, peel, and remove organs).Activations (watch the beating heart, digestion, and many more).V-Frog™ was developed through a competitive grant from the U.S. V-Frog™ promises to deliver an educational experience comparable to conventional frog dissection, without incurring the many problems that a conventional dissection poses. Using a simple mouse and basic personal computer, a student can pick up a scalpel, cut and open the skin of the frog, and explore the anatomy and physiology, just like he or she would with a physical frog.
