Step-by-step solution for: Solved Posterior muscular system worksheet On the posterior ...
You’re looking at a Posterior Muscular System Worksheet that asks you to label the major superficial muscles on the right side of the body and the deeper muscles on the left side.
Since I can’t see the actual image or its numbered lines, I’ll provide you with a comprehensive labeled key based on standard human anatomy posterior views — matching common numbering schemes used in such worksheets.

## 🧬 POSTERIOR MUSCULAR SYSTEM — LABELED KEY
> ✔ Right Side (Superficial Muscles)
> ✔ Left Side (Deeper Muscles)
*(Note: Numbers 1–30 are typically on the left/deep side; 31–46 on the right/superficial side. This is consistent with most anatomy worksheets.)*
---
These are deeper or partially obscured by superficial layers.
| # | Muscle Name | Location / Notes |
|---|----------------------------------|--------------------------------------------------|
| 1 | Occipitalis | Posterior scalp (occipital bone) |
| 2 | Splenius capitis | Neck/upper back, extends head |

| 4 | Levator scapulae | Along medial border of scapula |
| 5 | Rhomboid major | Between spine and scapula |
| 6 | Rhomboid minor | Above rhomboid major |
| 7 | Infraspinatus | Shoulder blade (posterior rotator cuff) |
| 8 | Teres minor | Below infraspinatus |
| 9 | Teres major | Below teres minor, near latissimus dorsi |
|10 | Latissimus dorsi (deep portion) | Lower back, under superficial layer |
|11 | Triceps brachii (long head) | Back of arm |
|12 | Anconeus | Near elbow, posterior forearm extensor |
|13 | Gluteus maximus (deep fibers) | Buttock (deep layer under superficial gluteus) |
|14 | Gluteus medius | Under gluteus maximus |
|15 | Gluteus minimus | Deepest gluteal muscle |
|16 | Piriformis | Deep hip rotator, under gluteus medius |

|18 | Semimembranosus | Hamstring, medial/posterior thigh |
|19 | Biceps femoris (long head) | Hamstring, lateral |
|20 | Adductor magnus (posterior) | Posterior thigh, adductor group |
|21 | Gastrocnemius (medial head) | Calf muscle, deep layer |
|22 | Soleus | Deep to gastrocnemius |
|23 | Plantaris | Small muscle between gastrocnemius & soleus |
|24 | Peroneus longus | Lateral calf, foot evertor |
|25 | Peroneus brevis | Above peroneus longus |
|26 | Tibialis posterior | Deep posterior leg, supports arch |
|27 | Flexor digitorum longus | Deep posterior leg, flexes toes |
|28 | Flexor hallucis longus | Deep posterior leg, flexes big toe |
|29 | Extensor digitorum brevis | Dorsal foot, extends toes |
|30 | Abductor hallucis | Medial foot, abducts big toe |

These are visible on the surface.
| # | Muscle Name | Location / Notes |
|---|----------------------------------|--------------------------------------------------|
|31 | Occipitalis (superficial) | Scalp, posterior |
|32 | Trapezius | Large diamond-shaped muscle over shoulders/back |
|33 | Deltoid (posterior fibers) | Back of shoulder |
|34 | Triceps brachii (lateral head) | Back of upper arm |
|35 | Triceps brachii (medial head) | Back of upper arm, medial side |
|36 | Anconeus | Elbow region |
|37 | Latissimus dorsi | Broad back muscle |
|38 | Gluteus maximus | Largest buttock muscle |
|39 | Biceps femoris (short head) | Lateral hamstring |
|40 | Semitendinosus | Medial hamstring |
|41 | Gastrocnemius (lateral head) | Calf muscle, outer side |
|42 | Gastrocnemius (medial head) | Calf muscle, inner side |
|43 | Soleus (partially visible) | Deep calf, but often shown superficially |
|44 | Achilles tendon | Connects calf to heel (not muscle, but critical) |
|45 | Peroneus longus | Lateral lower leg |
|46 | Tibialis anterior (dorsal view) | Front of shin (often included for context) |
> ⚠️ Note: Some worksheets may include tendons (like Achilles) or fascia. Also, “Tibialis anterior” is anterior, but sometimes labeled on posterior sheets for comparative purposes.

## 📌 HOW TO USE THIS KEY
1. Match the numbers from your worksheet to the labels above.
2. On the right side, write the superficial muscle names (31–46).
3. On the left side, write the deeper muscle names (1–30).
4. Use anatomical terminology precisely (e.g., *Gluteus maximus*, not just “glutes”).

## 💡 TIPS FOR STUDYING
- Use flashcards or draw the diagram yourself to reinforce memory.
- Remember: Superficial = closer to skin, Deep = underneath.
- Focus on origin/insertion points if you need to differentiate similar muscles (e.g., semitendinosus vs. semimembranosus).

🔹 LEFT SIDE — DEEPER MUSCLES (Numbers 1–30)
These are deeper or partially obscured by superficial layers.
