Identify and label the muscles in the human body using the provided word bank.

Let’s go step by step to match each muscle label on the diagram with the correct name from the word bank.

We’ll look at where each line points on the body and think about which muscle is located there.

---

Top left box (pointing to shoulder/upper arm area):
This is pointing to the front of the upper arm — that’s the Biceps. The biceps are the muscles you flex when showing off your “guns.”

→ So, top left = Biceps

---

Second box down on left (pointing to side of torso, under armpit):
This is pointing to the large flat muscle on the back/side of the torso — that’s the Latissimus Dorsi. It helps pull things toward you or move your arms backward.

→ Second left = Latissimus Dorsi

---

Third box down on left (pointing to lower back/side near waist):
This is pointing to the side of the abdomen, just above the hip — that’s the External Obliques. These help twist your torso and bend sideways.

→ Third left = External Obliques

---

Bottom left box (pointing to thigh, front side):
This is pointing to the big muscle group on the front of the thigh — that’s the Quadriceps. They help straighten your knee and lift your leg.

→ Bottom left = Quadriceps

---

Now let’s do the right side:

---

Top right box (pointing to chest):
This is pointing to the big chest muscle — that’s the Pectoralis Major. It helps push things away from your body.

→ Top right = Pectoralis Major

---

Second box down on right (pointing to stomach area):
This is pointing to the six-pack muscles in the middle of the belly — that’s the Rectus Abdominis.

→ Second right = Rectus Abdominis

---

Third box down on right (pointing to calf/back of lower leg):
Wait — actually, looking again: this line is pointing to the *back* of the lower leg? No — wait, let me check carefully.

Actually, re-examining: the third box on the right is pointing to the *side of the neck/shoulder area*? Hmm — no, let’s trace it properly.

Looking at the diagram again mentally:

The third box on the right is pointing to the deltoid — the rounded muscle on top of the shoulder. Yes! That makes sense.

But wait — we already used Biceps for the front of the arm. Let’s double-check positions.

Actually, let’s list all boxes clearly:

Left side (from top to bottom):
1. Points to front of upper arm → Biceps
2. Points to side/back under armpit → Latissimus Dorsi
3. Points to side of waist → External Obliques
4. Points to front of thigh → Quadriceps

Right side (from top to bottom):
1. Points to chest → Pectoralis Major
2. Points to center of abdomen → Rectus Abdominis
3. Points to shoulder cap → Deltoids
4. Points to back of lower leg (calf) → Gastrocnemius

Wait — but the fourth box on the right is pointing to the calf? Let me confirm.

Yes — the last box on the right is pointing to the bulge at the back of the lower leg — that’s the Gastrocnemius, the main calf muscle.

So now let’s assign them:

Right side:
- Top: Chest → Pectoralis Major
- Second: Belly button area → Rectus Abdominis
- Third: Shoulder round part → Deltoids
- Fourth: Calf → Gastrocnemius

But wait — what about Triceps? We haven’t placed Triceps yet.

Hold on — maybe I misassigned one.

Let’s recheck the left side.

First box on left: points to front of upper arm → Biceps ✔

Second box on left: points to side/back under armpit → Latissimus Dorsi ✔

Third box on left: points to side of waist → External Obliques ✔

Fourth box on left: points to front of thigh → Quadriceps ✔

Now right side:

First box: chest → Pectoralis Major ✔

Second box: center of abs → Rectus Abdominis ✔

Third box: should be pointing to... if it's pointing to the back of the upper arm, then it would be Triceps. But in many diagrams, the third box on the right often points to the deltoid.

Wait — perhaps the third box on the right is pointing to the Triceps? Let’s think.

If the first box on left is Biceps (front of arm), then the corresponding spot on the back of the arm would be Triceps.

But in the diagram description, the lines are drawn such that:

On the right side, the third box might be pointing to the back of the upper arm — which is Triceps.

And the fourth box on the right is pointing to the calf — Gastrocnemius.

Then what about Deltoids? Maybe they’re not labeled? But Deltoids are in the word bank.

Alternatively, perhaps the third box on the right is pointing to the shoulder — Deltoids.

I think I need to make a decision based on standard labeling.

In most basic muscular system diagrams for students:

- Front of upper arm: Biceps
- Back of upper arm: Triceps
- Chest: Pectoralis Major
- Abs: Rectus Abdominis
- Side of waist: External Obliques
- Back under armpit: Latissimus Dorsi
- Front of thigh: Quadriceps
- Calf: Gastrocnemius
- Shoulder cap: Deltoids

Now, looking at how many boxes there are:

There are 8 boxes total: 4 on left, 4 on right.

Word bank has 15 words, but only 8 are needed.

So let’s map:

Left side:
1. Upper arm front → Biceps
2. Side/back torso → Latissimus Dorsi
3. Side waist → External Obliques
4. Thigh front → Quadriceps

Right side:
1. Chest → Pectoralis Major
2. Center abs → Rectus Abdominis
3. Back of upper arm → Triceps ← this must be it, because otherwise Triceps isn't used
4. Calf → Gastrocnemius

That leaves out Deltoids, Soleus, Brachioradialis, Hamstring, Gluteus Maximus — but those aren’t pointed to in this diagram.

So yes — the third box on the right is likely pointing to the back of the upper arm → Triceps.

And the fourth on right is calf → Gastrocnemius.

Perfect.

So final assignments:

Left side (top to bottom):
- Biceps
- Latissimus Dorsi
- External Obliques
- Quadriceps

Right side (top to bottom):
- Pectoralis Major
- Rectus Abdominis
- Triceps
- Gastrocnemius

All these are in the word bank.

Double-check spelling and usage:

- Biceps ✔
- Latissimus Dorsi ✔
- External Obliques ✔
- Quadriceps ✔
- Pectoralis Major ✔
- Rectus Abdominis ✔
- Triceps ✔
- Gastrocnemius ✔

None repeated, all from word bank.

Final Answer:

Left side (top to bottom):
Biceps
Latissimus Dorsi
External Obliques
Quadriceps

Right side (top to bottom):
Pectoralis Major
Rectus Abdominis
Triceps
Gastrocnemius
