Step 1: Understanding the Concept
Humans have three pairs of salivary glands: parotid, submandibular and sublingual.
Step 2: Locate the parotids
The parotid glands are the largest pair. They lie in the cheeks, just in front of each ear, and open through Stensen's duct.
Step 3: Other glands
The submandibular glands lie below the lower jaw and the sublingual glands lie below the tongue.
Step 4: Conclusion
Parotid glands occur in front of the ear.
Final Answer:
The parotid salivary glands are located in front of the ear.
