Another runs into the interval between the sterno - mastoid and digastric muscles; and a pharyngeal process is occasionally found running medially anterior to the styloid process towards the side of the pharynx. A pterygoid extension, between the two pterygoid muscles, cannot properly be said to exist. Embedded in the superficial surface there are usually found several small rounded lymph glands, which can be recognised from the gland tissue by the difference in their colour.

The prevertebral muscles and the stylopharyngeus (which is shown just at the medial side of the external carotid artery) are not indicated by reference lines. The facial process of the gland—often of considerable size—is a fiat and some- what triangular portion which runs forwards from the upper part of the front of the gland, and overlaps the masseter muscle to a varying extent; from its most anterior part the parotid duct emerges, and a separated portion of this process, often found lying immediately above the duct, is known as the glandula parotis accessoria ( socia parotidis).
