The image you've uploaded is a
Muscles Worksheet that shows a human body with various muscles labeled by lines pointing to blank boxes. The goal of this worksheet is to identify and name the major skeletal muscles based on their location.
Since I cannot see the actual labels or names in the image (as it's a blank diagram), I will provide the
correct names for the major muscles typically labeled in such diagrams, corresponding to the positions indicated by the arrows. Below is a
step-by-step guide to help you fill in the blanks correctly.
---
🔹 Head & Neck Muscles
1.
Frontal belly of the occipitofrontalis – forehead area
2.
Orbicularis oculi – around the eyes
3.
Zygomaticus major – cheek area, involved in smiling
4.
Orbicularis oris – around the mouth
5.
Masseter – jaw muscle, large square-shaped
6.
Temporalis – temple area
7.
Sternocleidomastoid – neck, runs from ear to collarbone
---
🔹 Upper Body Muscles
8.
Trapezius – upper back and neck
9.
Deltoid – shoulder
10.
Pectoralis major – chest
11.
Biceps brachii – front of upper arm
12.
Triceps brachii – back of upper arm
13.
Brachialis – under biceps
14.
Flexor carpi radialis – forearm, inner side
15.
Extensor carpi ulnaris – forearm, outer side
---
🔹 Core Muscles
16.
Rectus abdominis – "six-pack" muscles
17.
External oblique – sides of abdomen
18.
Internal oblique – deeper layer of abdominal wall
19.
Erector spinae – along the spine (back)
---
🔹 Lower Body Muscles
20.
Gluteus maximus – buttocks
21.
Adductor longus – inner thigh
22.
Quadriceps femoris – front of thigh (includes rectus femoris, vastus lateralis, etc.)
23.
Hamstrings – back of thigh (semitendinosus, semimembranosus, biceps femoris)
24.
Gastrocnemius – calf (larger, superficial muscle)
25.
Soleus – deep calf muscle, below gastrocnemius

✔ How to Fill In the Worksheet:
Match each numbered label (based on arrow position) to the correct muscle name above. For example:
- Arrow pointing to the
forehead:
Frontal belly of the occipitofrontalis
- Arrow pointing to the
jaw:
Masseter
- Arrow pointing to the
chest:
Pectoralis major
- Arrow pointing to the
abdomen:
Rectus abdominis
- Arrow pointing to the
thigh:
Quadriceps femoris or
Hamstrings, depending on side
- Arrow pointing to the
calf:
Gastrocnemius or
Soleus
---
📌 Tips:
- Use anatomical landmarks: e.g., the
deltoid is on the shoulder, the
trapezius extends from the neck to the upper back.
- Remember:
"Biceps" = two heads,
"Triceps" = three heads.
- The
quadriceps are four muscles on the front of the thigh;
hamstrings are three on the back.

If you can describe the exact positions of the arrows (e.g., “top left of head”, “inner thigh”, etc.), I can give more precise labeling.
Let me know if you’d like a printable version or a labeled diagram!
Parent Tip: Review the logic above to help your child master the concept of muscular system worksheet for high school.
