submandibular

DEFINITION of submandibular

The submandibular region is the area inferior- to the body of the mandible, within the submandibular (digastric) triangle bounded by the anterior and posterior bellies of the digastric muscle and the inferior border of the mandible. The primary structure here is the submandibular gland, the second-largest salivary gland (after the parotid), weighing ~15g each, contributing 60-67% of resting saliva via its seromucous secretions through Wharton’s duct (submandibular duct), which opens at the sublingual caruncle beside the lingual frenulum. The gland has superficial and deep lobes separated by the mylohyoid muscle; the superficial lobe lies against the mandible, while the deep lobe wraps around mylohyoid posteriorly. Blood supply is from facial and lingual arteries; parasympathetic innervation via chorda tympani (facial nerve) to submandibular ganglion stimulates watery secretion, while sympathetic input via superior cervical ganglion produces viscous enzyme-rich-rich saliva.
