Blood supply, Lymphatic Drainage and Nerve supply to the Salivary Glands

Salivary Glands are mostly divided into Major and Minor Salivary glands, the major salivary glands are mainly Parotid, Submandibular and Sublingual glands and  Location of Minor Salivary Glands

Parotid gland:

Nerve supply – Auricotemporal nerve
Blood supply – External Carotid artery via the Posterior Auricular artery and the Transverse facial
Venous Drainage – Retromandibular vein
Lymphatic Drainage – Preauricular or Parotid Lymph nodes which ultimately drain to the Deep Cervical chain

Submandibular Glands:

Nerve Supply:Submandibular Ganglion
Blood Supply: Glandular Branches of Facial Artery
Lymphatic Drainage: Submandibular Lymph Nodes

Sublingual Salivary Glands

Nerve Supply: Submandibular ganglion
Blood Supply: Sublingual artery a branch of external carotid artery
Venous Drainage: Similar to Blood supply
Lymphatic Drainage:Submandibular Nodes

Minor Salivary Glands:

Nerve Supply: Parasympathetic innervation from the Lingual nerve, minor glands of the palate receive their parasympathetic fibers from the Palatine nerves, from the Sphenopalatine ganglion.
