Parotid gland glandula parotidea

The parotid gland is a salivary gland at the base of the ear; its saliva reaches the mouth through a duct that runs across the cheek.

The four layers use the same contour: exterior with body regions, superficial muscles, skeleton and organs.

What it is and what it does

The parotid gland lies in the retromandibular region, between the ramus of the mandible, the base of the ear and the superficial part of the masseter; its upper end is wide and notched by the base of the ear. The parotid duct crosses the masseter and opens into the mouth, opposite the upper cheek teeth. The sources do not agree on its size relative to the mandibular gland, so the atlas does not compare them.

Worth remembering

Its duct opens opposite the upper back teeth: that is why the cheek gets wet there.

Names
