Where does the submandibular gland wrap around anatomically?
Show answer and explanation
Correct answer: B. Mylohyoid muscle
The submandibular gland wraps around the posterior free margin of the mylohyoid muscle. The superficial portion lies below the mylohyoid; the deep portion extends above it. This anatomic relationship is clinically important during submandibular gland surgery and when calculating radiation field for salivary gland tumors. The Wharton's duct opens on the floor of the mouth at the sublingual caruncle.
- A. ❌ The digastric muscle forms the floor of the submandibular triangle but the gland wraps the mylohyoid.
- B. ✅ CORRECT – The submandibular gland hooks around the posterior free border of the mylohyoid muscle.
- C. ❌ The hyoglossus is related to the tongue and hypoglossal nerve — the submandibular gland does not wrap around it.
- D. ❌ The genioglossus is a tongue muscle with no direct wrapping relationship with the submandibular gland.
