Educational muscle system worksheet for learning human anatomy.

To solve this muscle system labeling task, we need to match each blank line on the diagram with the correct muscle name from the word bank at the bottom.

Let’s go step by step, using body location clues:

1. Top left (face area) → The lines point to muscles around the eyes and mouth. That’s clearly Face muscles.

2. Left side, upper arm front → This is the bicep area. So that’s Biceps.

3. Left side, behind arm → The label says “behind arm” — that’s the triceps. So Triceps.

4. Left side, chest area → Pointing to the big chest muscle → Pectoral.

5. Left side, stomach area (front abs) → The six-pack muscle → Rectus Abdominus.

6. Left side, thigh front → Big front thigh muscle → Quadriceps.

7. Left side, back of thigh → Label says “behind leg” → That’s the Hamstring.

8. Right side, shoulder → Top of the arm/shoulder → Deltoid.

9. Right side, side of waist/torso → Side abdominal muscles → Obliques.

10. Right side, lower back/buttock area → Large buttock muscle → Gluteus maximus.

11. Right side, calf/shin front? → Wait — let’s check: one line points to the front of the lower leg (shin), another to the back of the ankle.

- Front of lower leg (shin) → Tibialis
- Back of ankle → Achilles tendon

12. Right hand/fingers → Muscles that bend fingers → Finger Flexors

Now let’s assign them in order as they appear on the diagram (left to right, top to bottom):

Starting from the top-left going down the left side, then across to the right side:

- Face → Face muscles
- Upper arm front → Biceps
- Behind arm → Triceps
- Chest → Pectoral
- Stomach → Rectus Abdominus
- Thigh front → Quadriceps
- Behind leg → Hamstring

Then right side:

- Shoulder → Deltoid
- Side torso → Obliques
- Buttock → Gluteus maximus
- Lower leg front → Tibialis
- Ankle/back of heel → Achilles tendon
- Fingers → Finger Flexors

Wait — there are 14 blanks? Let me count the lines on the diagram:

Actually, looking again — there are 14 labeled lines total? No — let’s recount based on standard anatomy worksheets like this.

Standard version has 14 labels? Actually, no — let’s list all the words given:

Word bank has:
- Quadriceps
- Biceps
- Tibialis
- Finger Flexors
- Triceps
- Hamstring
- Deltoid
- Face muscles
- Gluteus maximus
- Pectoral
- Obliques
- Achilles tendon
- Rectus Abdominus

That’s 13 terms.

Diagram likely has 13 blank lines.

Let’s map them precisely by position:

Assume the diagram has these positions (from top to bottom, left to right):

LEFT SIDE:
1. Face → Face muscles
2. Upper arm front → Biceps
3. Behind arm → Triceps
4. Chest → Pectoral
5. Abs → Rectus Abdominus
6. Front thigh → Quadriceps
7. Back of thigh → Hamstring

RIGHT SIDE:
8. Shoulder → Deltoid
9. Side waist → Obliques
10. Buttock → Gluteus maximus
11. Front shin → Tibialis
12. Back of ankle → Achilles tendon
13. Fingers → Finger Flexors

Yes — that matches all 13 terms.

So final matching:

From top to bottom, left column first, then right column:

Left:
- Face muscles
- Biceps
- Triceps
- Pectoral
- Rectus Abdominus
- Quadriceps
- Hamstring

Right:
- Deltoid
- Obliques
- Gluteus maximus
- Tibialis
- Achilles tendon
- Finger Flexors

But wait — the diagram may have the lines arranged differently. Since we can’t see exact line numbers, we must rely on anatomical logic.

Another way: sometimes the “behind” labels help.

The diagram has two explicit hints:
- “behind arm” → Triceps
- “behind leg” → Hamstring

Also, “behind” near the hip/glute area → Gluteus maximus

And “behind” near ankle → Achilles tendon

So let’s use those anchors.

Final verified assignment:

Based on standard human muscle diagrams for kids:

TOP ROW (head/neck/shoulders):
- Left face → Face muscles
- Right shoulder → Deltoid

UPPER BODY:
- Left upper arm front → Biceps
- Left behind arm → Triceps
- Left chest → Pectoral
- Right side torso → Obliques

MID BODY:
- Left abs → Rectus Abdominus
- Right buttock → Gluteus maximus

LOWER BODY:
- Left front thigh → Quadriceps
- Left behind leg → Hamstring
- Right front shin → Tibialis
- Right back ankle → Achilles tendon
- Right fingers → Finger Flexors

All 13 accounted for.

Since the question doesn’t ask for a specific format, but just to “solve the problem”, which means fill in the blanks correctly, we provide the matched pairs.

But since it’s a worksheet, probably expects the answers listed in order of the lines on the page.

Without seeing exact line numbering, safest is to list them by body region as above.

However, many such worksheets arrange the lines vertically on each side.

Assuming left side has 7 lines (top to bottom), right side has 6 lines (top to bottom):

Left side (top to bottom):
1. Face → Face muscles
2. Upper arm → Biceps
3. Behind arm → Triceps
4. Chest → Pectoral
5. Abs → Rectus Abdominus
6. Thigh front → Quadriceps
7. Behind leg → Hamstring

Right side (top to bottom):
8. Shoulder → Deltoid
9. Side torso → Obliques
10. Buttock → Gluteus maximus
11. Shin → Tibialis
12. Ankle → Achilles tendon
13. Fingers → Finger Flexors

This uses all 13 terms correctly.

Final Answer:

Face muscles
Biceps
Triceps
Pectoral
Rectus Abdominus
Quadriceps
Hamstring
Deltoid
Obliques
Gluteus maximus
Tibialis
Achilles tendon
Finger Flexors
