The image shows a virtual frog dissection simulation, and you're at
Step 07: Horizontal muscle incisions. Here's how to solve the task based on the instructions:

🔍 Task Description
You are instructed to:
> *"Use the forceps and scalpel to make an incision just above the rear limbs. Take care not to cut too deeply."*
This is part of a dissection process where you're preparing to expose internal structures by carefully cutting through muscles.

✔ Step-by-Step Solution
1.
Select the Tools
- From the
TOOLS panel, select:
-
Scalpel (to make the incision)
-
Forceps (to hold or retract tissue if needed)
2.
Position the Scalpel
- Place the scalpel just
above the base of the rear limbs (where the legs meet the body).
- This area is typically where the horizontal abdominal muscles are located.
3.
Make a Horizontal Incision
- Make a
horizontal cut across the abdomen,
just above the hind legs.
- The cut should be
shallow—only through the skin and superficial muscles.
- Avoid cutting into deeper organs or blood vessels.
4.
Use Forceps for Assistance
- Use the
forceps to gently pull or hold back the skin or muscle layers to help guide the scalpel safely.
- This prevents accidental deep cuts.
5.
Check Your Work
- Ensure the incision is clean and horizontal.
- Do not go too deep—this could damage vital organs like the intestines or kidneys.

🧠 Why This Step Matters
This incision helps open the abdominal cavity to access internal organs such as the liver, stomach, intestines, and reproductive organs. It’s important to be precise so you don’t damage structures you want to study later.

⚠️ Tips
- Always use
light pressure with the scalpel.
- If you see red (blood), stop—this indicates you’ve cut too deeply.
- Keep the frog pinned down securely to avoid movement during the cut.

✔️ Final Outcome
After completing this step correctly:
- You’ll have a
clean horizontal incision just above the hind legs.
- The next steps will likely involve spreading the incision and examining the internal anatomy.
