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.
