  • Description

    • * Nestled under skin and fascia, overlying jawbone (ramus), from TMJ to angle.
    • * Divided into superficial and deep lobes, facial nerve (CN VII) separates them.
    • * Produces serous saliva rich in alpha-amylase for aiding carbohydrate digestion.
    • * Parotid duct exits deep lobe, opening on cheek mucosa opposite upper second molar.
    • * Blood Supply:
    • * External carotid, maxillary, and facial arteries.
    • * Venous Drainage:
    • * Retromandibular vein, empties into jugular vein.
    • * Innervation: • Parasympathetic fibers of facial nerve (CN VII) for saliva production.
