ECA Branches

Branches Vascular Supply and Anastomoses
**Superior thyroid artery (A)** Larynx and upper thyroid
Thyrocervical trunk (branch of the subclavian artery) supplies the inferior
thyroid and isthmus.
**Ascending pharyngeal artery (M)** Nasopharynx, oropharynx, and middle ear
CNs IX, X, and XI
Meninges
Anastomoses with the vertebral artery branches
**Lingual artery (A)** Tongue and the floor of the mouth
**Facial artery (A)** Face, palate, and lips
Angular branch of the facial artery anastomoses with the orbital branch of the ophthalmic artery.
**Occipital artery (P)** Posterior scalp, upper cervical musculature
Posterior fossa and meninges
Anastomoses with the vertebral artery
**Posterior auricular artery (P)** Pinna, external auditory canal, and scalp
**Superficial temporal artery** Scalp and ear
**Internal maxillary artery (aka Maxillary Artery)** Deep face
Gives off the middle meningeal artery (MMA) and accessory meningeal arteries
Anastomoses with inferior lateral cavernous sinus trunk and ophthalmic artery through ethmoidal branches
