FREE! - Matching and Labelling Human Body Chart - Primary Resource - Free Printable

The image you've provided is a labeled diagram of the main anterior (front) muscles of the human body. The task appears to be identifying and labeling each muscle group indicated by the lines pointing to various parts of the body.

Since the labels are currently blank, I will provide the correct names for each muscle based on standard human anatomy. Below is a detailed explanation with the correct labels corresponding to each line from top to bottom:

---

Head and Neck Region:

1. Frontal belly of the occipitofrontalis – Located on the forehead; raises eyebrows.
2. Orbicularis oculi – Around the eye; closes eyelids.
3. Orbicularis oris – Around the mouth; controls lip movements.
4. Masseter – A powerful jaw-closing muscle on the side of the face.
5. Sternocleidomastoid – Runs from the sternum/clavicle to the skull; turns head and flexes neck.

Upper Body (Torso & Arms):

6. Pectoralis major – Large chest muscle; adducts and flexes the arm.
7. Deltoid (anterior fibers) – Front part of shoulder muscle; helps in arm flexion.
8. Biceps brachii – On the front of the upper arm; flexes elbow and supinates forearm.
9. Brachialis – Underneath biceps; primary elbow flexor.
10. Brachioradialis – On the forearm; flexes elbow.
11. Flexor carpi radialis – Inner forearm; flexes wrist.
12. Palmaris longus – Thin muscle in forearm; may be absent in some people; assists wrist flexion.
13. Flexor digitorum superficialis – Flexes fingers.
14. Abdominal muscles (rectus abdominis) – "Six-pack" muscles; flex the spine.
15. External oblique – Side abdominal wall; rotates and bends trunk.

Lower Body (Legs):

16. Adductor longus – Inner thigh; addsucts leg.
17. Gracilis – Thinnest adductor; also helps with hip adduction.
18. Vastus medialis – Part of quadriceps; extends knee.
19. Vastus lateralis – Outer quadriceps muscle; extends knee.
20. Rectus femoris – Topmost quadriceps muscle; crosses hip and knee joints.
21. Tibialis anterior – Front of lower leg; dorsiflexes foot.
22. Extensor digitorum longus – Extends toes and dorsiflexes foot.
23. Peroneus longus – Outer lower leg; everts foot and plantarflexes ankle.
