Which structure is contained in the digastric (submandibular) triangle of the neck?

• A. Cervical plexus
• B. Submandibular gland
• C. Phrenic nerve
• D. Vagus nerve

Answer: (B)

The submandibular triangle, also known as the digastric triangle, is an important anatomical region of the neck. It is bounded by the mandible and the two bellies of the digastric muscle. This region primarily houses the submandibular gland, which is one of the major salivary glands. The submandibular gland is a key structure for saliva production, aiding in digestion and oral health. Its location in this triangle is vital for various surgical and diagnostic procedures, as its intimate relationship with surrounding structures, such as the facial artery and vein, is significant in clinical practice. While the cervical plexus, phrenic nerve, and vagus nerve are crucial in other aspects of cervical anatomy, they do not reside within the boundaries of the digastric triangle. The cervical plexus supplies sensory and motor innervation to parts of the neck, the phrenic nerve is located more posteriorly and supplies the diaphragm, and the vagus nerve runs in the carotid sheath alongside the common carotid artery and internal jugular vein, which is also outside of the submandibular triangle. By understanding the anatomy of the submandibular triangle, healthcare professionals can effectively navigate this region during examinations,
