# Relations of Hyoglossus Muscle

Understand the superficial and deep relations of the hyoglossus muscle useful for anatomy theory and viva. Watch the full video lecture on YouTube: https://www.youtube.com/watch?v=DZzpL8NLtHc

The **relations of the hyoglossus muscle** is an important short question topic for your anatomy theory exams and can also come up in viva, especially in cases involving the tongue.

These relations are best understood when divided into two categories:

- **Superficial (Lateral) Relations**
- **Deep (Medial) Relations**

### 🔍 Deep (Medial) Relations of Hyoglossus

These are the structures **deep to the hyoglossus muscle**, i.e., on its **medial side**. Though not all are easily visualized, it's important to remember them in relation to the muscle’s **origin** and **insertion**.

🧠 **Tip:** You might need to **memorize** these as they are not as easily seen during dissection or visualized.

#### ✅ List of Deep/Medial Relations:

- **Inferior longitudinal muscle of the tongue** (near the insertion)
- **Middle constrictor of pharynx**
- **Second part of the lingual artery** (close to origin)
- **Stylopharyngeus muscle**
- **Glossopharyngeal nerve**
- **Stylohyoid ligament**
- **Junction of 1st and 2nd parts of the lingual artery** (deep to posterior border of hyoglossus)

### 🧊 Superficial (Lateral) Relations of Hyoglossus

These are the structures **lateral to the hyoglossus**, lying **between the hyoglossus and the mylohyoid muscle**.

🎯 **Remember:** You can understand these better if you think of them from **above downwards**, as they pass in that direction between the two muscles.

> 📌 **Important:** Always draw a diagram when answering this in exams. It helps with better recall and shows the examiner your conceptual clarity.

#### 🔽 From Above Downwards:

1. **Mucous membrane** of the side of the tongue
2. **Styloglossus muscle**
3. **Lingual nerve** (usually seen in green in diagrams)
4. **Submandibular ganglion**  
   - Suspended from the lingual nerve by **two roots**
5. **Deep part of the submandibular gland** and **submandibular duct**
6. **Hypoglossal nerve**  
   - Accompanied by a **pair of veins**
7. **Suprahyoid branch of the 1st part of the lingual artery**
