Which structure is NOT supplied by the maxillary artery? A)nose B)teeth of upper jaw C)teeth of lower jaw D)Tongue

To determine which structure is NOT supplied by the maxillary artery, we can analyze the options provided with respect to the branches and supply areas of the maxillary artery.

1. Understanding the Maxillary Artery Supply:
   The maxillary artery is one of the main arteries supplying deep facial structures, including branches that provide blood to the maxilla, nasal cavity, upper teeth, and parts of the tongue.

2. Analyzing Each Option:

   • A) Nose: The maxillary artery supplies the nasal cavity through its branches (e.g., sphenopalatine artery).
   • B) Teeth of Upper Jaw: The maxillary artery provides blood supply to the maxillary teeth via the superior alveolar arteries.
   • C) Teeth of Lower Jaw: The lower jaw teeth are mainly supplied by the inferior alveolar artery, which is a branch of the mandibular nerve, not the maxillary artery.
   • D) Tongue: The tongue is supplied by other arteries, primarily the lingual artery, which is a branch of the external carotid artery, not the maxillary artery.

3. Conclusion:
   Among the options, the structure that is NOT supplied by the maxillary artery is the C) teeth of lower jaw.

Final Answer

C) teeth of lower jaw
