Thyrocervical trunk (branch of the subclavian artery) supplies the inferior
thyroid and isthmus. |
| **A**scending pharyngeal artery (M) | Nasopharynx, oropharynx, and middle ear
CNs IX, X, and XI
Meninges
Anastomoses with the vertebral artery branches |
| **L**ingual artery (A) | Tongue and the floor of the mouth |
