Where are the submandibular lymph nodes located?

The submandibular lymph nodes are located under the jaw, specifically in the area where the mandible (lower jaw) meets the neck. These nodes play an essential role in draining lymphatic fluid from the region of the head and neck, including the floor of the mouth and the tongue. Their strategic location under the jaw allows them to effectively filter potential pathogens and facilitate immune responses.

Understanding the anatomical position of the submandibular lymph nodes is crucial for recognizing their function in veterinary medicine, especially when assessing conditions such as infections or swellings in the oral cavity or surrounding structures. Lymph node assessment is a common practice during physical examinations in veterinary settings to provide insights into an animal's health status.
