Insertion. The geniohyoid muscle inserts on to the anterior and upper surface of the body of the hyoid bone.
Is the digastric triangle superior to the anterior triangle?
Like the anterior triangle, the digastric ( submandibular) triangle is limited superiorly by the same structures. Its inferior boundaries are formed by the posterior belly of the digastric and stylohyoid muscles posteriorly, and the anterior belly of the digastric muscle anteriorly.
What makes up the digastric triangle of the neck?
The digastric triangle houses submandibular gland and lymph nodes (anteriorly), caudal part of the parotid gland (posteriorly), facial artery and vein, submental artery and vein, lingual arteries and veins, mylohyoid nerve and the hypoglossal nerve (CN XII).
