First Steps • Rinse frog in water • Obtain frog and place frog on its dorsal (back) side. Pin limbs to dissection tray
Making Incisions • Use forceps to lift frogs skin between rear legs. Use scalpel to cut through lifted skin. AB CD EF
Exposing the Muscular Tissue • Lift one flap of skin with the forceps. (separate muscle layer from skin) • Pin the flaps of skin to the dissection tray • Make a vertical incision through the abdominal muscle (use scissors up until just before the front legs) • Cut through chest bones vertically then make lateral cuts
Exposing the Chest Cavity • Use forceps to pull back and hold muscle flaps. Use scalpel to separate organ from muscle tissue. • Pin flaps to dissection tray.
Exposing the Organs • Use forceps to pick up the triangular flaps of skin and muscle below the front legs. • Pin the flaps back enough to access body cavity
