Student Lab Worksheet: Frog Dissection - External Anatomy Diagrams 1 and 2.

Let’s go step by step to label the external anatomy of a frog using Diagram 1 and Diagram 2.

First, look at Diagram 1 — it shows the side view (lateral view) of the frog. The lines point to different parts on the head and body.

From top to bottom in Diagram 1:
- The top line points to the eye → that’s the Eye
- The next line down points to the nostril area → that’s the Nostril (or External Nares)
- Then there’s a line pointing to the mouth opening → that’s the Mouth
- Below that, near the throat area, is the Tympanic Membrane (eardrum) — it looks like a circular patch behind the eye
- The last line at the bottom points to the front leg → that’s the Forelimb

Now, Diagram 2 — this is the ventral view (belly side) of the frog. The lines are on the left side of the frog’s body.

From top to bottom in Diagram 2:
- Top line: points to the shoulder area → Shoulder
- Next: elbow joint → Elbow
- Then: wrist area → Wrist
- Then: fingers/toes on the front foot → Digits (or Toes)
- Bottom line: points to the belly area → Abdomen

Wait — let’s double-check standard frog external anatomy labels for these diagrams.

Actually, in most school worksheets:

Diagram 1 (side view):
Top to bottom:
1. Eye
2. Nostril
3. Mouth
4. Tympanum (eardrum)
5. Forelimb

Diagram 2 (ventral view, left side):
Top to bottom:
1. Shoulder
2. Elbow
3. Wrist
4. Digits (toes of forelimb)
5. Abdomen

Yes, that matches common labeling.

So now we can write the answers clearly.

Final Answer:
Diagram 1 (from top to bottom):
1. Eye
2. Nostril
3. Mouth
4. Tympanum
5. Forelimb

Diagram 2 (from top to bottom):
1. Shoulder
2. Elbow
3. Wrist
4. Digits
5. Abdomen
