Where is the submandibular lymph node located?

• A. Midway between the angle and the tip of the mandible
• B. Posterior to the ear within the parotid region
• C. Under the chin near the midline
• D. In the posterior neck along the SCM

Answer: (B)

The submandibular lymph nodes sit along the inferior border of the mandible, in the submandibular triangle, typically about halfway between the angle of the mandible and the chin. This position matches their drainage areas—facial regions like the lips, cheeks, floor of mouth, and the anterior two-thirds of the tongue funnel into these nodes.

So the location described as midway along the lower jaw is the correct one. In contrast, nodes behind the ear within the parotid region are the parotid (retromandibular) nodes, under the chin midline are submental nodes, and along the posterior neck near the sternocleidomastoid are deep cervical nodes.
