Label Muscles Worksheet - Free Printable

This is a Muscles Worksheet designed to help students learn and identify major muscles in the human body. The diagram shows the anterior (front) view of the human muscular system, with labeled lines pointing to various muscle groups. The task is to fill in the blank boxes with the correct names of the muscles.

Let’s go step by step and identify each muscle based on its location:

---

Head & Neck:

1. Top center (forehead) – *Frontalis*
→ Controls facial expressions, raises eyebrows.

2. Above the eye (eyebrow area) – *Orbicularis oculi*
→ Closes the eyelids.

3. Cheek area – *Zygomaticus major*
→ Pulls the corners of the mouth upward (smiling).

4. Lower face (jawline) – *Masseter*
→ Powerful chewing muscle.

5. Neck (side) – *Sternocleidomastoid*
→ Flexes the neck and rotates the head.

6. Below jaw (neck) – *Platysma*
→ Flattens the skin of the neck.

7. Side of the neck (deep) – *Trapezius*
→ Upper back/neck; helps move the shoulder.

Upper Body:

8. Shoulder (top of arm) – *Deltoid*
→ Covers the shoulder joint; allows arm movement.

9. Chest (large fan-shaped) – *Pectoralis major*
→ Adducts and flexes the arm at the shoulder.

10. Upper arm (back side) – *Triceps brachii*
→ Extends the forearm (straightens the elbow).

11. Upper arm (front side) – *Biceps brachii*
→ Flexes the elbow (bends the arm).

12. Center of chest (rectangular shape) – *Rectus abdominis*
→ "Six-pack" muscles; flexes the trunk.

13. Side of abdomen – *External obliques*
→ Rotate and bend the trunk.

14. Underneath chest (under pectoralis) – *Serratus anterior*
→ Stabilizes the scapula.

15. Back of upper arm (near shoulder) – *Teres minor*
→ Part of rotator cuff; externally rotates the arm.

Lower Body:

16. Thigh (front) – *Quadriceps femoris*
→ Group of four muscles that extend the knee.

17. Thigh (back) – *Hamstrings*
→ Flex the knee and extend the hip.

18. Outer thigh – *Gluteus medius*
→ Abducts the hip and stabilizes pelvis.

19. Buttocks (main muscle) – *Gluteus maximus*
→ Largest muscle in the body; extends the hip.

20. Calf (back of lower leg) – *Gastrocnemius*
→ Plantarflexes the foot (pushing off when walking).

21. Lower leg (outer side) – *Fibularis longus*
→ Everts the foot and plantarflexes it.

22. Lower leg (inner side) – *Tibialis anterior*
→ Dorsiflexes the foot (pulls toes up).

23. Back of calf (deep) – *Soleus*
→ Assists gastrocnemius in plantarflexion.

24. Upper thigh (adductor region) – *Adductor magnus*
→ Adducts the thigh (brings leg toward midline).
