The parotid gland is a pair of salivary glands, located on each side of the face, right below and in front of the external ear. Being the largest of the three pairs of salivary glands, it secretes seromoucus saliva into the mouth through the parotid duct. The gland is crisscrossed by branches of the facial nerve, dividing it into a superficial and a deep part. The parotid glands are supplied by the transverse facial artery, which is a branch of superficial temporal artery.
