You can also identify the rest of its organs using diagrams to identify what you find. You can cut that open if you want to have a look. First, you will be able to find the frog’s heart, which has three chambers and is located near the center of its body. Frogs have a truly fascinating internal organ system. Once you have completed the cutting, you should be able to get a good look at everything inside the frog.
Frog dissection test skin#
You should now be able to pull away all of the skin here and expose the frog’s. Go back again with the scalpel this time and you should now be slicing into thicker muscles. Once this is done, make horizontal cuts near its arms and legs. Be careful to only cut the outer skin – you don’t want to cut into any internal organs.Ĭut all along the frog’s body from the bottom of its neck until you get to the bottom of the body. Then, use the dissection scissors to slice the frog’s stomach open, slitting the abdominal muscles.
Safety rules should always be observed when you are handling anything that was once alive.įirst, begin the dissection by using the scalpel to place small cuts on the skin between the frog’s legs. Before starting, remember to put on the protective gear (the gloves and goggles). Then, the pins should be used to pin the limbs to the tray so the frog stays in place during the dissection. The frog needs to be rinsed in water and placed in a tray on its back. Make sure you set up the frog dissection station correctly and know the tools well.
If you use a living frog, you will have to put it in a bottle or jar and drop a cotton ball of chloroform to put it into deep sleep. It is recommended that you get a preserved frog. To dissect a frog, you need these things : a tray, pins, forceps, scalpel, dissection scissors, gloves, goggles, and probes.
Fortunately, there are good instructions to help students do the right things and complete the frog dissection successfully. The exercise can be pretty messy if you don’t know what you’re doing. One of the highlights, or lowlights, of a biology class is the dissection of a frog.
