Final answer:
The lymph nodes located anterior to the tragus of the ear are the parotid lymph nodes, associated with the parotid glands.
Step-by-step explanation:
The lymph nodes found anterior to the tragus of the ear are the parotid lymph nodes. These nodes are associated with the parotid glands, which are the largest of the three major pairs of salivary glands. The parotid glands are located on either side of the mouth, in front of the ears, between the skin and the masseter muscle. They secrete saliva into the mouth through the parotid duct, which has an opening near the second upper molar tooth.
